Geo 730: June 16, Day 532: Pebbly Sandstone

This is a fairly weathered surface, and I'm unable to identify most of the clasts other than quartz. It's a portion of the Tyee surrounding the coal of the last few days. In this view, it looks to be dominated by sand with a large, but still lesser, component of pebbles. The latter are clearly rounded, but are still angular enough that they don't look to have been transported too far. Tomorrow's shot, from the same boulder, is markedly different...
