mamooth is correct. Don't go wandering off in the desert without first educating yourself and knowing exactly what you're up against. Remember that many migrant workers die in that desert.
I lived for more than 25 years in the Sonora desert and hiked a lot. Its an incredible place, beautiful and hostile. BE aware that there is no GPS or cell signal in much of the desert.
Because of its high rain fall and the huge array of flora and fauna, its a "sub-tropical desert". This is also why its so difficult to find illegals. During some times of the year and/or in some areas, you could hide elephants in the Sonora desert.
Hotter than hell during the day and freezing cold at night. The plant life is fascinating, as is the wildlife. Be prepared for everything. That includes rattlesnakes and scorpions although, its only
the small bark scorpion that is dangerous to people. I've been stung by a scorpion, very painful. I did get to the point where I could catch the giant desert hairy scorpion by its stinger in order to take it outside.
If you go to Tucson, visit the Arizona Sonora Desert Museum and the Tucson Mountains Visitor Center that is just up the road from the museum. That road ties into the road I lived on - very wild and beautiful. Check out the websites for both, as well as Desert USA.
Also make sure you know where the Indian reservations are. They will always take you in and help you. Honestly, you can count on Native Americans and Mexicans to rescue you. They will give you the shirt off their back. When whites would pass you up, they will always stop to help you and it really does behoove you to know where they are.
