I may not be in Edward Abbey land (Moab, Utah) but I love this quote. If you haven't read Desert Solitare you should.
I visited White Sands National Monument in New Mexico on my way to Tucson. The dunes were pretty awesome. I've been to Great Sand Dunes NP in CO, but this was a little different. For one thing, unlike dunes made of quartz-based sand crystals, these dunes are made of gypsum which does not readily convert the sun's energy into heat and so you can walk on it in bare feet, even in the hottest summer months. Of course I didn't know this at first and I was later amazed that the sand was actually cool to the touch. It was the first place I had ever seen people sledding on sand.
