GeoSights—Comb Ridge, San Juan County, Utah

One may say Comb Ridge was Mother Nature’s way of splitting southern San Juan County with an enormous
wall. Another may say it was a giant skateboard ramp for dinosaurs. One thing is certain: Comb Ridge is a spectacular
ridge of steeply tilted sandstone rock layers, trending north-south for approximately 80 miles from Utah’s Abajo Mountains to Kayenta, Arizona. Similar to a rooster’s comb, the jagged appearance of Comb Ridge provides the logic behind its name.
