The Meridian Mysteries and the Secret of Time

The Chaco and Mayan Meridians

In 1990 while studying rock art in the American southwest, James Jacobs noticed that Aztec Ruins and Chaco Culture were on the same meridian or north-south longitude line, and he raised the point with the archaeological community. Then in 1991, he expanded his view to include sites in Mexico, adding Paquimé to the ‘Chaco Meridian’, and he identified a ‘Mayan Meridian’ running through sites in the Yucatán to Tikal in Guatemala. Jacobs believes that this is evidence that ancient Americans practiced geodesy or took accurate measurements of Earth’s size, and he provides analysis of arc distance ratios to support his theory.

In 1999, Stephen Lekson wrote a book called The Chaco Meridian, bringing wider attention to Jacobs’ discovery. But Lekson argues that this is only evidence that the ancient people moved in straight lines north and south. He believes the Ancestral Puebloans used a series of north-south visual bearings to align the sites on the Chaco Meridian, and he points to the great north-south roads of Chaco.

Some critics dismiss both theories and argue that there are so many ancient sites scattered all over North America that any straight line will pass through 3 or more, so any meridian is merely coincidence. So, who’s right?

UNESCO recognizes 20 Pre-Columbian settlements as World Heritage Sites in North America, including 1 pre-Mayan, 8 Mayan, 3 Ancestral Puebloan, 5 other contemporaries of the Maya, and 3 post Mayan. All three of the UN-recognized Ancestral Puebloan sites are at 108º longitude: Chaco, Mesa Verde and Paquimé. 6 of the Mayan sites are at 89º longitude: Calakmul, Chichén Itzá, Copan, Quirigua, Tikal and Uxmal. The other 2 Mayan sites are Palenque at 92º and Tak’alik Ab’aj at 91.5º. But Palenque and Tikal are both at 17º latitude. So 100% of the UN-recognized Ancestral Puebloan and Mayan sites are on the same longitude or latitude lines. Unintentionally, UNESCO confirms both meridians.

The Difficulty of Calculating a Meridian

So, how did the ancient native people build cities on the same latitude and longitude lines before GPS and even before 250 BCE when the Greek Erosthenes first recorded the idea of plotting longitude and latitude on a grid?

Calculating latitude is easy in the northern hemisphere. Simply measure the angle between the North Star and the horizon. If it’s 90º then you are at the North Pole, and your latitude is 90º. If it’s 0º, then you’re at the equator, latitude 0º.

Calculating longitude accurately is much more difficult, since although the stars stay in place, we orbit the sun every year and rotate every 24 hours. Every 4 minutes, the Earth turns one degree of longitude. So to calculate your longitude, you need to measure a star’s angle on a specific date and time, which requires both a calendar and an accurate measurement of time. For example, we know that the sun is directly overhead at noon, and if we knew which star was directly overhead at midnight on a given date, then we would know our longitude.

Lekson’s theory of north-south visual bearings might possibly explain the now desert Chaco Meridian sites, but I’ve driven the route which includes some rough elevation changes that would have made it extremely difficult to take accurate bearings over hundreds of miles, even with signal fires. And Lekson’s theory fails completely on the Mayan Meridian, due to the jungle. The hilly Yucatán terrain is covered by fast growing tall trees in a thick jungle that’s difficult to pass. While they built temples that reached above the treetops, that doesn’t explain how they chose the sites in the jungle before building the tall temples. There’s certainly no view of the horizon from the middle of the jungle, even if you clear all the trees for a few miles. So any line of sight explanation is wrong.

Alien Technology or Magic?!?

But the experts say that neither the Ancestral Puebloans nor the Mayans kept time accurately. So, the lack of a satisfactory explanation for how ancient people could apparently calculate longitude has caused a few people to imagine that either aliens gave technology to the Mayans or that some other magic knowledge of invisible Earth energy—ley lines—is the explanation. No.

Cultural Clues to Calculations

While his original book was criticized for a few errors, Lekson is correct that there is a cultural connection between the ancient sites that made the meridians important to the people who built temples there. The sites share some historic overlapping, they were on established trade routes, and there are some basic architectural similarities, such as buildings oriented north-south. Agricultural societies are acutely aware of seasons, and each season has a different view of the stars at night as the earth orbits the sun. There are observatories at many sites, including at Chichén Itzá below, at Palenque and Xochicalo—with view holes in the observatory roof similar to a planetarium—, so there’s lots of evidence that accurate angles could be calculated on specific days and even at specific times of night. So Lekson’s basic theory, that there was an educated priestly elite with detailed knowledge of astronomy that likely traveled between sites, fits the known facts well.

Importantly, the three main sites on the Chaco Meridian all have advanced irrigation systems. The Greeks used water flowing through fixed diameter holes to measure time, like an hourglass measures time with the flow of sand. Surely, some Ancestral Puebloans tried to measure accurately how long their water supply would last. Yet for some reason, the idea that the ancient North American natives could calculate time is dismissed.

The Mayans were obsessed with the passage of time. The Mayan calendar has 365 days, uses a base 20 number system, and describes cycles of both 52 years and 5,125 years. You may have heard that the Mayans predicted the end of the world on December 21st, 2012. What they actually said was that their long count would reset on that day to begin a new five millennia era. Counting the days and monitoring the sun were central to their daily lives. The pyramid at Chichén Itzá has 365 steps, and the shadow of a serpent appears to climb them on the solstices. They believed the Sun God brought order to the day and transformed into a jaguar to pass through the perilous night.

And similar beliefs were common across pre-Columbian civilizations. From the Caves of Mitla & Yagul to El Tajin’s 365 daily shadowed alcoves, the ancients contemplated the underworld and the sun’s ordered journey across the sky. The tallest temple in Mexico is the Temple of the Sun at Teotihuacán, where a ‘town crier’ would beat his drum to signify important events. And yet some experts today would stand at the feet of the pyramids, perfectly aligned with the sun at noon, while shadows cast points across the plazas and claim that not one of the ancient people knew the time of day.

I do not understand how anyone can argue that the Mayans recorded their dynasties for centuries without having any interest or ideas on how one might calculate shorter time periods. These ancient agricultural societies had tens of thousands laboring in the fields, military groups coordinating jungle raids, traders delivering on precise daily schedules over hundreds of miles—in Tenochtitlan Montezuma ate fresh fish carried by relay runners from the Pacific—, and had thousands of laborers building precise pyramids, and yet some otherwise smart folks maintain the absurd position that none of the natives had any idea how long a day was nor could anyone organize anything that today requires a clock.

The simplest and only remaining logical explanation of the meridians is that some elite of both the Ancestral Puebloans and Mayans had a rudimentary way to calculate time accurately, most likely some type of shadow tracking and water flow systems, as they used both. They may have guarded that secret and kept it from the masses, but someone must have figured out how to tell time or there would be no meridian mysteries. Once we recognize that ancient American astronomers had the ability to measure time accurately, then we know that they could measure the angle of the a star on a particular day and time and calculate their relative longitude at different places. The time would only need to be accurate to within a few minutes at each location in order to mark a new temple within a degree of any known meridian, even in the jungle without a view of the horizon.

But Why Did They Build on Meridians?

But why bother? This is another problem with Lekson’s theory. Even if you accept that ancient people were very attuned to direction and solstices, such annual calendaring doesn’t require longitude at all, while latitude is only incidentally useful. So what’s the practical benefit of building two buildings on the same meridian? For that matter, why bother calculating the size of the earth, if Jacobs is correct about ancient American geodesy? Who cares that the arc distance between two distant buildings is 1% of the circumference of the globe, especially if your number system isn’t even based on 10 or 100?

To understand why, consider your last visit to a planetarium show. They likely showed which constellations appeared in the skies on that date and showed how the stars moved over time. If an ancient priest knew in advance which stars would rise into the sky at what time, then they could plan to tell a story about the stars that fit each day of the year. We know from many sites that the ancient Americans had a deep belief system involving day and night, believing that the labor of those on earth and the struggles of those in the underworld were connected to the rise of the sun each day. The stories of the stars may have revolved around heroes or rulers who had passed on to the afterlife, like the Greek myths that appear in the constellations.

If you had two temples on the same meridian, you could tell the exact same story on the same day beginning at the same time, and the sky would follow your words precisely. Even in daylight, using the same measuring sticks, the shadows would appear exactly at the moment you predict. This, perhaps, was the purpose of building your most important temples on the same meridian: to demonstrate the power of math and knowledge before the ignorant masses.

Although much of the history, language and culture of the ancient Americans was lost, the Yucatán pyramids and great kivas of the southwest have survived, demonstrating that there were at least a few ancient people who maintained the same astrological, calendaric, cartographic, chronologic, geometric, mathematical and navigational knowledge across generations and across cultural boundaries. They intentionally convinced others to build multiple cities on the same meridians to keep their predictions and myth-making consistent for at least a thousand years. The alignment of North American Native American World Heritage Sites proves this indisputably, without a plausible, logical alternative explanation. And if we refuse to recognize their accomplishments that still stand today, then we are the ignorant and irrational ones.

Palenque

Palenque is both photogenic and filled with important hieroglyphics, describing the rulers who lived and were buried here, especially Pakal the Great, who ruled the city for most of the 600s. Even arriving at 8 am, the popular archaeological site already had a few bus loads of tourists, especially Europeans who are currently avoiding Mexico’s northern neighbor. Part of the jungle loop trail was blocked, so I didn’t see any monkeys or toucans, but I did see an agouti, which is a fairly big, long-legged rodent that’s critically endangered. I spent most of my time appreciating the various carved stone monuments on top of the palace above. The tower is an observatory, and beside it there’s a sunken courtyard memorializing defeated rivals.

It’s wonderful to see many important artifacts still on site, although many of the finest are in museums now. The ancient Mayan builders were skilled at vaulted ceilings, and I admired the stonework in the tomb of the Red Queen, whose sarcophagus is indeed colored red inside. Being able to step inside the pyramid at all is a rare treat, and, although Pakal’s tomb is closed, there’s a large replica at the Anthropology Museum in Mexico City. Many of the inscriptions—which reveal the royal history—are partially covered or off limits to preserve them, and considering the age and jungle atmosphere, the ones I saw were in remarkably good condition due to higher quality stone and innovative carving techniques. Most of the site is still covered by jungle, where new discoveries await.

Overall, Palenque is an excellent site, a mix of well-tended atmospheric grounds, grand architecture, historical importance, intricately detailed art, jungle ruins and active digs.

Chichén Itzá

/ bigdiff / 1 Comment

As they have for over one thousand years, vendors sell art, crafts, fabrics, jewelry, and more near the grand pyramid at Chichén Itzá. As usual, the experts downplay the role of merchants here, but since merchants are included in a number of the elaborate carvings here, they cannot be forgotten. One area is designated as a market, and it is likely that more of the buildings were also used for commerce. It must be remembered that the Mayans did not use the wheel much, so it wasn’t practical to move goods any more than necessary. Nobody wants to carry around large amounts of copper, jade and obsidian on their back. Except maybe thieves. One of the plaques mentioned that the roads may have included checkpoints, which again makes sense if you’re trying to protect your treasure from raiders.

The guides explain in great detail about the ball courts—including the largest in the Americas—, calendars, gods and temples, which is all interesting, but I wonder why they used to sacrifice humans by throwing them into their own drinking water supply. Even though the water is replenished by an underground river system, that wouldn’t be tasty or wise, even if you’re pre germ theory. Perhaps the most sacred cenotes were more ceremonial and were not always used for drinking water as some guides claim. It’s difficult to imagine a highly organized society thrived for centuries without strict rules.

Anyway, this is a magnificent UNESCO world heritage site with both many intricate details and grand structures, once protected from colonial excavation by a few centuries of jungle overgrowth. The Mayans used exceptionally durable stone and mortar here, conveying their sophisticated culture to us in sharp relief. Consider El Castillo—Kukulkán, the feathered serpent—below, with 91 steps per side, which chirp like a Quetzal in echo response, perfectly and artistically aligned with the solstices casting serpentine shadows, plus one step on top, making 365 steps to mark the year. For 2,000 years Native American people have marked the days with similar calendar accuracy, displaying their advanced mathematical literacy at the core of their accomplished civilization.

Death Valley Lows: Tragedy, Madness & Our National Parks

/ bigdiff / Leave a comment

On Valentine’s Day in 1884, both the wife and mother of a young Teddy Roosevelt died of illnesses, leaving him with a two day old daughter. The young Harvard graduate and successful author resigned from the NY Assembly, and he went out west to mourn in the wilderness. His experiences would bring him through battle with his rough riders in Cuba to the White House, where he repaid his debt to nature by protecting 230 million acres of public land. Presidents Lincoln and Grant—no strangers to suffering—had already protected Yosemite and Yellowstone respectively, and in 1903 President Roosevelt camped in each park with Muir and Burroughs respectively, expanding Yosemite and changing from hunter to wildlife observer in Yellowstone. As parks or monuments Teddy signed into law Crater Lake, Grand Canyon, Lassen Volcanic, Mesa Verde, Olympic, Petrified Forest, Pinnacles and Wind Cave, plus Chaco, Devils Tower, El Morro, Gila Cliff Dwellings, Jewel Cave, Montezuma Castle, Muir Woods, Natural Bridges, Tonto, and Tumacacori.

But my hero Teddy Roosevelt is not the man I write about today. The secret behind the first NPS Director, Stephen Mather, was hidden from view until 1987 when his faithful assistant and successor revealed near the end of his own life that Mather was suicidally bipolar. A contemporary and kindred spirit of Muir and Roosevelt, Mather climbed Mt Rainier in 1905, explored Kings Canyon and Sequoia and helped found Save the Redwoods. Upset over the inconsistent and weak protection in the parks he visited, Mather lobbied Washington and got a job as Assistant Secretary of the Interior. Using his own funds, he organized an expedition and invited the head of the Appropriations Committee and the press, including the National Geographic Society editor. Mather’s enthusiasm was both manic—jumping into waterfall pools—and inspiring. As a direct result, President Wilson created the National Park Service, and Mather became its first leader.

Despite his months-long ‘Death Valley lows’ Mather was responsible for many of the decisions that converted protected public lands into the National Park experiences that we enjoy today. He pushed back the loggers, miners and ranchers who were extracting private wealth from our public lands. He lobbied to create many park units, including Indiana Dunes (postponed due to the urgency of WWI). He had iconic lodges built, like Old Faithful Inn above, and he limited development in many spectacular parks to just one dramatically scenic road. These exuberant and thrilling experiences in nature were his ‘Going to the Sun highs’, and he devoted all his energy to perfecting them. Mather was a staunch environmental defender, a visionary parks evangelist, and a brilliant marketer who wanted to share the joy of these wonderful places with everyone.

Humans have long sought solace in nature, so preserving havens in national parks is essential for humanity. People like Stephen Mather, who suffered from debilitating bouts of deep depression, desperately need nature both to recover from sadness and to be inspired into joyful action. This human bond with natural beauty and affinity with wildlife is what drove Teddy Roosevelt to rebound from his tragedies and Stephen Mather to overcome his mental illness. And as President and NPS architect, both worked tirelessly to protect our public lands for future generations.

Mather is well remembered in many NPS sites, from Mather District in Yosemite, Mather Gorge at Great Falls, Mather Parkway at Rainier, Mather Point in Grand Canyon and Mount Mather in Denali. His friends created bronze Mather plaques that can be found at over 50 park units across the country. Despite our current crazy and dangerous warming of our atmosphere, the plaques thank Mather with the following quote.

“He laid the foundation of the National Park Service, defining and establishing the policies under which its areas shall be developed and conserved unimpaired for future generations. There will never come an end to the good that he has done.”

Uxmal

/ bigdiff / 1 Comment

There’s nothing like a Mayan city surrounded by jungle, and Uxmal (oosh-mal) is a grand one. I drove up through the Yucatán hill country and visited Labná first, which is a smaller part of this UNESCO world heritage site, then I stayed nearby so I could explore Uxmal in the morning before the crowds arrived. I even spotted a large coati while walking behind the vantage point above. The tall building on the right is called the magician’s house, and if you clap in front of the steps, the echo makes a musical sound like a chirp.

I have decided that some archaeologists are not very good at their jobs. I’ve seen a decent number of ancient Native American cities now, and they typically describe the various building purposes as bureaucratic, religious, royal residences, and sometimes military uses. For example, the wide building in the center above is called the nun’s house, as it reminded the Spanish of a convent’s courtyard, I suppose. But rarely do any of the site maps indicate any commercial buildings, according to the experts. Maybe some archaeologists lack real world work experience, if they go straight from grad school to dig sites?

The Mayans had a thriving economy, receiving tribute, growing crops, gathering medical plants, mining minerals, weaving textiles, and producing various goods, tools and art. They traded turquoise with Arizona, obsidian with Tinochtitlan, cinnabar and alabaster with Teotihuacán, salt with Oaxaca, copper and gold, cotton, jade, feathers, fish and much more, and all of these goods—the wealth of the empire—required storage. Food had to be distributed widely and quickly to support large concentrations of people. And trading requires markets where goods can be examined and merchants can show the quality of work. But somehow archaeologists forget about all that when they try to figure out what all the empty buildings and rooms were for.

Why are there rows of rectangular windowless rooms with wide doors facing a courtyard? Why are there long colonnades? Well, in Europe and in most other countries the same structures would immediately be recognized as market stalls, as in the forum of Rome. Does anyone really believe that valuable salt was stored outside in the rain? The Catholic Spanish assumed most ancient buildings in New Spain must have been about religion, and many Americans—perhaps biased by years of war history—often assume that every wall had a military purpose. Some folks just assumed that Native American civilization was only savage sacrifice and war.

And I know it’s easy to get distracted by the art, ball games, calendars, math, and elaborate funereal figurines, but a little common sense would help us understand that many of these buildings must have been involved in commerce, which must have been part of the daily routine for most Mayans. In any case, it is a privilege to visit these ancient sites and get a new perspective.

Frog Soup

We celebrate both the ocean and the great outdoors in June. So, let’s talk about how our global temperature will continue rising uncontrollably for the foreseeable future.

The US burned more fossil fuels than any other country, polluting our atmosphere with excess carbon pollution and increasingly trapping more heat near the planet surface every year. The rate of warming is accelerating, and every decade is now over 1/2º F higher than the last, already over 10 times faster than natural warming after an ice age. And we have chosen to ignore it and keep burning more fossil fuels.

Our polar ice caps and ice age glaciers are melting. The Arctic Ocean will be free of ice at least one day in late summer within a few years—likely 2027 to 2030–, and without the reflective ice to keep the surface cool, the ocean surface temperature will soar. As our oceans warm and surface ice melts, the water expands, raising the sea level globally. Warmer waters kill coral reefs, disrupt ocean currents, cause toxic algae blooms, and create acidified, deoxygenated dead zones. This will cause many fisheries to collapse.

Still, from day to day we may not notice the change in climate. The earth still spins causing distinct weather patterns in the northern and southern hemispheres. The earth’s axis still tilts, and our planet still orbits the sun unevenly, causing the seasons. So our meteorologists still focus on the daily highs and lows, precipitation forecasts, and seasonal patterns, lulling us into familiar comfort.

But make no mistake. Like frogs in a pot, we are slowly cooking instead of jumping into action to save ourselves.

El Tajin

/ bigdiff / Leave a comment

The Pyramid of the Niches still has almost all of its original 365 small alcoves used to mark the rebirth of each day of the year, and to store various meaningful reminders like a giant advent calendar. The passage of time was participatory in native civilizations, as the people toiled on the ground to keep the heavens turning and the sun rising to overcome the darkness. Calendaring was useful for organizing labor, managing produce and tracking seasonal trade goods.

El Tajin was a city of commerce in the highland jungle of the Veracruz river valley where large scale agriculture developed thousands of years ago. Some guides wrongly imagine that the central structures were home to bureaucrats toiling away in offices—as in modern governments. But, like the Forum of Rome, the first-built main square was a marketplace built to organize and accommodate large scale trade. The multicultural community grew in wealth and importance especially from around the 7th century, trading vanilla and cacao with cities like Teotihuacán. Great structures were built around the 8th and 9th centuries, and even as other cities succumbed to fire, El Tajin thrived through the 12th century. Then it too collapsed and was reclaimed by the jungle until rediscovered in 1785.

The surrounding ball courts must have attracted visitors and entertained crowds, but the games were brutal and sometimes involved human sacrifice, similar to the Colosseum of Rome, where the gladiators entered the ring saying, “we who are about to die, salute you”. While you can’t climb on any of the thousand year old buildings, the grassy grounds are uncrowded and very pleasant to explore.

The fliers from the neighboring city of Papantla frequently perform outside the ticket booth for a small donation, acknowledging the four directions, and attracting rain with music and rainbow hats. One on top also drums and stamps his feet, recalling ‘the thunder’, the meaning of El Tajin.

Both El Tajin and the Papantla Flyers are recognized by UNESCO as part of our world heritage.

Ría Celestún Biosphere

This UN recognized biosphere in the northeast Yucatán is also a tentative world heritage site, and in the winter it has thousands of flamingos! A short drive from Mérida, I bought my ticket at the Parador Turístico and waited 5 minutes for four more tourists to join my boat, and we zoomed off to see the beautiful birds. After watching flocks of flamingos flying and feeding in the shallow estuary—ría—, we went off to see more birds. In the mangrove tunnel, I spotted the bare throated tiger heron below with his neck stretched up to look like a stick, but when we got close he realized his cover was blown.

We also walked a boardwalk to a freshwater spring-fed lagoon and saw a baby crocodile, lots of pelicans, great & snowy egrets, wood storks, and a roseate spoonbill. But for me, the surprise was seeing flamingos in flight. I’ve seen a few flamingos in zoos, but I’ve never seen so many gathered together honking, chattering, flapping, bowing and preening. Instead of looking silly or awkward, here their displays look natural and beautiful, especially flying in formation. One of my favorite stops in Mexico.

This UNESCO World Heritage Site and Biosphere on the southeast coast of the Yucatán has exceptional species diversity in jungles, mangroves, shallow bays, reefs, islands and open water. On my day tour we saw many great birds including tiger heron, roseate spoonbill, osprey and frigate birds, crocodiles and green turtles, and dolphin and many tropical fish, of course. While I don’t believe I saw any first time species for me, I definitely saw a greater variety than I can remember seeing in one place before.

The reserve is huge, with a long low peninsula, a fishing village at the end of an extremely bumpy road, a surprisingly healthy looking ocean reef, and a huge salt lagoon with mangrove islands, shallow flats, and some freshwater springs bubbling up into the lagoon for manatees to enjoy. Even if you think you can get here, it’s worth it to join a tour with an expert guide, a van driver, and a flat boat captain. I particularly enjoyed chatting with my new friends from all over the world while standing waist deep in turquoise water and drinking a well-deserved Mexican cerveza.

National Parks to Visit in June

/ bigdiff / Leave a comment

I recommend Badlands, Great Smoky, Teddy Roosevelt, Yellowstone and Wind Cave in June. These popular parks are big enough to accommodate some crowds, are more fun in summer, and are even busier in July and August.

The Badlands are at their mildest in June, with wildlife about and even some greenery. Spend some time soaking in the scenery from a campground, time your hikes for the sun angles and weather, and listen to a ranger talk at an amphitheater. You won’t have the place to yourself, but do you really want to be in the Badlands by yourself?

Great Smoky in June is good for seeing bears, fireflies, and for swimming holes or rafting, so no wonder it’s so popular. Plan ahead and spend some time camping here, so you can visit the most popular spots on weekday mornings. Take your time hiking and ask folks what they’ve seen.

Teddy Roosevelt is another fun park that’s great in June. I enjoyed driving to all three park units, hiking and enjoying wildlife and scenic viewpoints. But if I go again, I’m going to stay longer. The folks at the campgrounds were very friendly and nice.

Yellowstone is the best park in the contiguous US and is big with lots to see and do. So you need to go when there’s good weather and activities are in full swing. Book campgrounds and activities well in advance, give yourself time for everything on your list, and go in June before it gets even busier in July and August. The grand old park can handle the crowds, but planning ahead is the key.

Wind Cave is crowded in summer, so common advice says to visit in May or September to avoid crowds and heat. But it’s a cave, so heat is not an issue. And the cave tours are all in guided groups, which are similar in size most of the year. So my advice is to visit when you’re visiting other parks above in the region. And you should absolutely book your tickets in advance. Bison can be seen outside the park entrance in June and other months.

June is a beautiful month, so take advantage of the fine weather, go camping and enjoy some of the best national parks in the country.
