The canyon walls that rose above his trapped arm for 127 hours were Navajo sandstone: the same rock that forms the arches of Arches National Park, the spires of Capitol Reef, the walls of Zion. It is a beautiful rock, layered in deep reds and oranges and pinks, with characteristic crossbedding patterns that reveal its origin as ancient dunes. It is also, in the quantities represented by an 800-pound chockstone, an unyielding substance against which no human physical force is decisive.
The canyon sits on BLM land in a region that sees relatively light traffic. It is accessible from the Maze-Robbers Roost Road, itself a rough track requiring high-clearance four-wheel-drive vehicles and significant navigation skill to use safely. The remoteness is not incidental to the story; it is essential to understanding why a search, even once initiated, took as long as it did to locate Ralston’s position. Search and rescue in canyon country is fundamentally different from search and rescue in more accessible terrain. A helicopter can see a person on an open slope. A helicopter cannot see into a three-foot-wide slot canyon. The technical demands of both entering and searching that terrain on foot are substantial.
The canyon country of southeastern Utah was, in 2003, as in the century before it, a place where the land’s indifference to human presence was the dominant fact. The outlaw history Ralston’s canyon carries in its name — the Blue John of the nineteenth-century horse thieves, the Robbers Roost hideout of Butch Cassidy — was not mythological romance. It was a description of terrain so difficult to access and navigate that it could hide people from the law for years. The same terrain that had sheltered outlaws from consequences could, in 2003, shield an injured man from rescue with equal indifference.
