Comb Ridge Panorama - Southern Utah

From National Geographic: 

Geologically speaking, the Comb is a monocline—a single fold in the Earth's crust created by a cataclysmic slippage of deeply buried tectonic plates some 65 million years ago. That upheaval has left a scar slashing across the desert landscape of the Southwest: a sharp ridge of sandstone that stretches almost 120 miles (193 kilometers) unbroken from just east of Kayenta, Arizona, to some ten miles (sixteen kilometers) west of Blanding, Utah.

The scale of the Comb is not colossal: Its ridgeline looms only from 300 to 900 feet (91 to 274 meters) above the plains, and shallow washes surround it on either side. But what the crest lacks in height, it makes up in ruggedness. No smooth arête, the ridge swoops to sharp summits and dips to V-notch cols with relentless regularity. To hike the Comb is to run a gauntlet of up-and-down severities, always at an ankle-wrenching, sideways pitch. There is not a single mile of established trail in the Comb's reach, which is one reason why no humans, to our knowledge, have ever traversed its length. We thought we should be the first.
