Our next stop was the Visitors' Center near the North Entrance in 29 Palms. Behind the Visitors' Center is another nature trail that goes around the Oasis of Mara. Back in the late 1800s and early 1900s this was a lush oasis, with water gushing out hundreds of gallons a minute. Since most oases are along fault lines, this was no exception. The Pinto Mountain Fault runs underneath, and when it shifted, the water source was redirected. There's still some water, enough to support the fan palms, but it's all well under the ground.
