Comb Ridge, Bluff

#4 of 9 in Things to do in Bluff
Comb Ridge is a linear north to south-trending monocline nearly 80 miles long in southeast Utah and northeast Arizona. Its northern end merges with the Abajo Mountains some eleven miles west of Blanding. It extends essentially due south for 45km to the San Juan River. South of the San Juan the ridge turns to the southwest and is more subdued in expression as it extends for an additional 67km to Laguna Creek 9km east of Kayenta, Arizona.
It was designated a National Natural Landmark in 1976 as the only North American location of tritylodont fossils. Parts of the ridge in Utah are protected as part of the Bears Ears National Monument.
The geologic formations involved in the east dipping strata of the fold include the Jurassic aged Navajo Sandstone, Kayenta Formation, Wingate Sandstone, Chinle Formation, Triassic Moenkopi Formation and Permian Organ Rock Formation. The structure is the surface expression of a deep fault along the east margin of the Monument Uplift.
