This little lady is an Eastern Collared Lizard, and she’s sitting on Alibates flint, which is an extremely hard and unusual type of flint used by Native Americans for sharp edged tools. These flints were used to hunt Mammoths (possibly to extinction) by the Clovis people over ten thousand years ago. (Clovis is the New Mexican town where they were studied). Successive groups of natives used these flints, notably the Antelope Creek tribe, who dug hundreds of quarry pits around here to dig out the best quality, unweathered flint, and traded them as far as Montana, California, Mexico and Alabama.

I’m not particularly interested in geology, but this was the funniest parks tour I’ve taken. The ranger, Ben, somehow got ten strangers roaring with laughter in ~100 degree heat while climbing a hill to look at rocks and taught us all lots of interesting facts along the way. He even got a Texas Horned Lizard (or “horned frog” or “horny toad”) to scramble in front of us, so we could all get a good look at the official lizard of the state. Actually, the only way into the park is by guided tour, and the only tour during the heat of summer is at 10am. Better to call and make a reservation.

If you are into geology, then this park is fascinating. There’s petrified algae, iron rich red beds, fossilized dolomite, salty gypsum, and of course the multi-colored, sometimes sparkly, agatized dolomite, known as Alibates flint. That name came from a cowboy guide named “Allie Bates”. Mysteriously, perhaps from Valles Caldera or Yellowstone volcanic activity, there was an abundance of silica-rich water that seeped into the dolomite and crystalized into a dense quartz along with an array of other colorful minerals. The flints have many of the rich colors and patterns of the mineralized trees found in the Petrified Forest.

I stayed the night in Palo Duro Canyon (2nd in size to the Grand Canyon) which is another great location for views of the colorful red, white, orange, and yellow rocks under a blue sky with lots of different green trees and plants. The night sky was also brilliant. Any recent rain can close roads though. There was a summer musical playing there for Texans about how wonderful the history of Texas is, but of course, it glosses over the theft of native lands and doesn’t mention slavery at all. It never occurred to me that Texans would be so insecure.
