Comb Ridge (Navajo: Tséyíkʼáán)[1] is a linear north to south-trending monocline nearly 80 miles long in Southeastern Utah and Northeastern Arizona. Its northern end merges with the Abajo Mountains some eleven miles west of Blanding. It extends essentially due south for 45 km (28 mi) 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 67 km (42 mi) to Laguna Creek 9 km (5.6 mi) east of Kayenta, Arizona.[2][3]
It was designated a National Natural Landmark in 1976 as the only North American location of tritylodont fossils.[4] Parts of the ridge in Utah are protected as part of the Bears Ears National Monument.[5]
