A day in the life...
Today I headed up to Red Rock Canyon to join LA County paleontologists on a prospecting journey and pick their brains for Kern County geology/paleontology info. It was great! Of course I found far more granite in a "granite-free" zone than bone fragments. I guess feldspars just jump out at me more.
Lignite layers in a wash (big wash walls!!!) containing itty bitty lake fossils, walls are undergoing biological weathering.
Rodent bitey marks on a bone fragment (see the little parallel grooves near the top of the bone shard?)
Angular unconformity and a hoodoo waiting to happen. Tilted layers of sands and ash, capped with nearly horizontal limestone.
