This photo submitted by John Holthaus is just too flat and dark, overall. So let's see what we can do to increase snap, contrast and detail.
First, pull out shadow detail (Image>Adjust>Shadow/Highlights and use the default settings). Then throw a classic S-curve in curves to rebuild contrast. And last, slide the mid tone pointer in levels a touch towards highlights to emphasize the texture differences on the lower part of the mountain.
