(Map site 6.) View looking northwest down the hinge of the Oat Mountain syncline. Beds of the Towsley Formation on the ridge to the left of the canyon are inclined downward toward the canyon. The same layers of the Sisquoc Formation on the ridge to the right of the canyon are also inclined downward toward the canyon. Between the two ridges the rocks are folded into a "U" shape. This type of fold is called a syncline.
