The Black Place is where Georgia O’Keeffe painted some of her most unique landscapes. It’s right opposite mile marker 111 on highway 550, but unfortunately it’s been taken over by oil drilling and the land is private and separated by barbed wire.
I visited on my way to an overnight in the Bisti Badlands, and managed to find a way to wander around a little bit using some little used dirt roads to get access. This was just a scout really, but it’s an amazing place. The black is from oxidized iron ash, and it’s a combination of the swamps, forest and river sediment that once covered it. Many of the hills are covered in montmorillonite clay, nicknamed ‘popcorn’.
