After lunch, Doug Yule (facing camera from behind the group) and Mike Kaericher (senior thesis student) described the significance of the rocks exposed along the ridge in the background. These rocks belong to the Neoproterozoic Wyman Formation. In the saddle on the right side of the photo are the brown, smooth-weathering, thin-bedded shale and carbonate beds of the typical Wyman Formation. Across the center of the photo are the slightly grayer, siliciclastic beds of the Hines Tongue of the Wyman Formation that was deposited in shallower water than the main Wyman Formation. On the left side of the photo are the more resistant, gray, blocky outcrops of the overlying Reed Dolomite.
