Have many of you ever heard (or been) in Cabeza Prieta National Wildlife Refuge"
Edward Abbey wrote about it in his story "A Walk In The Desert Hills."
I used to go there and sprint from Ajo to Yuma, cross country (Abbey took an old road) in 4 or 5 days. Always right around New Year. I would hike in the Arctic during the summer. Now I have a knee replacement that won't hold that weight or abuse again. I'm a connoisseur of wilderness, though.
Only the north area is now the Barry Goldwater Gunnery Range, but back after WWII, pretty much the whole place is full of debris. There are lots of big 4-finned wooden tow targets, covered with thin shiny aluminum, in some of the valleys, but you are likely to find them anywhere more than 15 miles north of the Mexican Border.
The San Cristobal Valley is filled with them, and there are all manner of empty cartridges laying everywhere from .50 cal on up to those big suckers that the A-10's shoot.
Some of the tow targets would "lawn dart."
It isn't much of a secret that Ed Abbey is buried there. He would turn over in his grave if he could see what the illegals and smugglers have done to the place. It is like a garbage can of empty water bottles and tuna cans. I don't go in there anymore because it is crawling with border patrol helicopters and their ninjas.
I love deserts, though. Take off with a pack full of five gallons of water and a few extra large snickers bars. When you begin to sweat, stop immediately and get in some shade if available. Then resume after you have cooled off. That is the trick. Man, have I drank some green goo that passed for water in some potholes in AZ. I really love Utah, and know of some secret spots in SW Canyonlands and Dark Canyon. It is easier to find water in there.
