Crushed Gravel

Crushed Gravel

Some of the geologic features of Yellowstone are unexpected. Old Failthful, Mammoth, and Lake Yellowstone get so much attention that some of the other features are easily overlooked, like this view from a boardwalk in Norris. The area here is very dry and it looks like it has been covered with crushed gravel from a leftover landscaping project. The depressions in the gravel were very clearly Bison hooves (with a few shoeprints mixed in).
