The last time I visited Badlands National Park was back in 1963. I remember a twisty labyrinth of narrow canyons, spires, and geologic formations reminiscent of Bryce or Cedar Breaks, soft crumbly sedimentary rock that in many places erodes too quickly for plants to put down roots. Vistas that stretched from the high plateau along the north of the park out to the southern plains. Sagebrush, prairie dogs, and antelope
