Picture of the Day

So what happened here? This is a stop on our eastern Sierra Nevada field studies course. It is on the road to Black Butte on the north shore of Mono Lake. The sediments are muds and ash fall units, and are probably only a few thousand years old. The site is about 2-3 miles west of the Sierra Nevada frontal fault system. Our students spend some time sketching and hypothesizing how these sediments might have formed.
