Geology at Iron Peak

This spot sits on Markagunt Megabreccia, Bear Valley Formation, volcanic mudflow breccia component, mapped as volcanic mudflow breccia that formed roughly 23 to 16 million years ago. Volcanic ground like this weathers into rocky slopes and float, and fresh exposures in cuts and drainages are usually the most productive places to look.
