Geo 1095: March 13, Day 802: Another Fold

Here Dana examines another flopped-over fold on the walk back from Oregon Caves to the parking area. The slightly more prominent and lighter band probably represents a bed with a little more silt and mud, and thus more (resistant) silicates. This is reinforced by the heavy jointing in that bed, which suggests it deformed more brittley than the purer and more plastic carbonates around it.
