The Mojave Desert in general, is a high altitude desert. I'm thinking that where we often camp is in the 4,000-5,000 foot elevation range. The ride up to MacGyvers Cabin, goes to over 7,000 feet (we have found snow there in March). It is also usually cooler than Dumont or Ocotillo Wells. There are lots of mining camps, Randsburg (a living ghost town), petroglyphs, and some rock crawling. Take lots of gas!
