Wanting to camp in desert areas in mid through late March but worried about spring break hikers and campers after reading about busiest times for Big Bend National Park. Anyone familiar with the western part of Texas and eastern half of New Mexico (maybe even south east Colorado) who would know of really great places to camp without people. In Missouri there is Prairie State Park which is even pretty much empty on Memorial day and Labor Day and certainly all of March. Any place similar out in the desert/high plains? If you know of a good enough spot that would work I would consider other options a bit farther north but the weather can get icy that time of year if I was to go to far up. We are looking for places with geologic interest and of course interesting plants and animals. A little history never hurts. I am a real nerd and can get excited over soil samples and my boyfriend loves bison. We also love dormant volcanoes. My boyfriend has a particular interest in badlands and collapsed volcanoes. Anyhoo, any advice?
