As we prepare to cross into a new year, take a moment to think about the high ground that divides the west from the east. Rivers, agriculture, ports and cities all are shaped and developed by changing elevation across the land. Watersheds support different species and define much of our history. Colonial America is set east of the Appalachians, along rivers like the Savannah, Susquehanna and Hudson that flow into the Atlantic, while the Ohio and Tennessee Rivers flow down the western slopes on their way to the Mississippi and Gulf of Mexico. But from Alaska to Tierra del Fuego, all of the Americas are divided by one great line of mountains and high elevations.
In the US, the 3,100 mile Forest Service managed trail starts at the New Mexico border, runs up near the Gila Cliff Dwellings, through El Malpais, cuts up west above Taos into Colorado, winds high through the Rockies, near Camp Hale, reaching its highest point at 14,270 feet on Gray’s Peak and then crosses through Rocky Mountain park (see photo). Here are the headwaters of both the North Platte River that flows east to the Mississippi and the Colorado River that flows west to the Sea of Cortez.
The trail continues north into Wyoming, where it crosses the Pioneer trails, through Yellowstone, where it crosses the Lewis & Clark trail, near the headwaters of both the Snake River which flows west to the Pacific and the Missouri River which flows east to the Mississippi. The mountainous divide continues up into Idaho and Montana, above Big Hole and Grant-Kohrs, connects with the Pacific Northwest trail and crosses through Glacier to Waterton in Canada. In Glacier, the epic trail summits Triple Divide Peak, which marks the hydrological apex of North America, where the Atlantic, Pacific and Arctic watersheds meet. Hope you have a happy new year!
