A 'Lave Flow' of Rock near Echo Rock

We've been doing a little exploring in the area near Echo Rock in Joshua Tree National Park lately. One morning we went straight to the east and around this large rock formation, following along the edge and came to what we call a 'lava flow' of rock. It just pours out from the rocks above creating this wonderful surface to walk on and explore all the little gullies and crevasses there. I kept going back to get more pictures and now it's one of our favorite spots to explore.
