These are a few photos taken last week while out mapping along the south flank of the Uinta Mountains. Ice Cave Peak gives a great view of the Whiterocks River valley and the rocks that are exposed along that valley. Late June is a great time to visit because the mountains are so green and the temperatures are pleasant. In the higher mountains, rain clouds form almost every afternoon.

[Image] View to southwest from Ice Cave Peak across Whiterocks River valley. On the far side of the river you can see, starting at the far left on the far ridge, gray outcrops of the Pennsylvanian Weber Sandstone, then red outcrops of the Morgan Formation, also Pennsylvanian. At the bottom of the red Morgan cliffs is a thinner gray cliff of Round Valley Limestone, completing the Pennsylvanian outcrops.  The Round Valley Limestone sits above a dark streak of green trees that are growing in the strike valley formed by the soft shale of the Doughnut Formation (Mississippian). Then at the top of the closer ridge, and still dipping off to the left, is a somewhat covered slope (with trees and scrub) of the Humbug Formation sitting atop several ledges with some trees that comprise the Deseret and Madison Limestones, all Mississippian in age. These Mississippian units sit unconformably on a yellow orange unit, called the Red Pine Shale. The Red Pine Shale here appears to be almost horizontal. It is the oldest unit in the photo and is Proterozoic in age. That's probably more geology than you really wanted to know.
