March 11th I led my club on a trip through the Geology Tour and Berdoo Canyon. It was snowing so it made for an interesting journey. Where the "tour" trail starts there were spots on rocks with snow, but none on the trail. The trail at this point is fairly smooth, easily driven by an automobile without 4x4. The scenery is full of Joshua Trees, Yuccas, and rocks. As the trail heads south, the vegitation and terrain, not to mention the condition of the trail, changes. The trail is frequently sandy and we cross an area with little vegitation and very flat, sloaping down to the valley floor. Passing what appears to be a cinder cone, we begin to climb and encounter snow on the trail. When we come to the junction where you can return to the valley or enter Berdoo Canyon, the snow is covering everything. At this point most of us engaged our four wheel drive to keep from sliding in the snow. When we wound our way down into Berdoo Canyon, it was obvious that the parks department has recently laid sand on the trail, since the most difficult part, the little "S" curve, while still requiring high clearance, could probably have been traversed without 4x4 if there hadn't been snow on the trail. The way out the canyon to Dillon Road had it's rough spots, mostly due to appearing, and then disappearing asphalt sections, and the rock "gate" near the end of the trail to keep wannabees out. All in all, a very pleasant trip, especailly with the snow.

Detailed Trail Descriptions from Our Guidebooks

"This is the shortest and easiest section of the trail. The obvious trail leads mostly downhill across the valley between Jumbo Rocks Campground and the Hexie Mountains. The hills in this part of the park are mostly ancient gneiss, accentuated with the occasional granite outcrop. Thin dikes of light-colored aplite criss-cross the desert and in several places they cross the trail. In about a mile, the trail leads past the south face of Crown Prince Lookout, a granite formation where a World War II airplane warning station was once perched."

"The self-guided Geology Tour loop in the park’s Pleasant Valley is a chance to see and learn about the park’s complex geology and its human history. Although it can be taken as a drive in its own right, it does connect to Berdoo Canyon Road."
