Rafting the Green River’s Desolation and Gray Canyons

By Michael Lanza

Our two prop planes climb to 2,000 feet above the Green River, flying north from the tiny airport in the one-horse town in southeast Utah that shares the river’s name. The brown current far below wiggles between castle-like walls in a canyon carved deeply into the Tavaputs Plateau, a twisting labyrinth of towers and sharp edges that looks not much more decipherable from up here than it does trying to navigate it down there. The early-morning sun slashes across the tops of the tallest formations—which are about level with us—but has not yet reached the shaded canyon bottom.

Most conspicuous, though, is what’s unseen: any significant footprint of civilization beyond an occasional rough, rambling line of hardened earth and rocks that constitutes what passes for a road out here. We are heading into one of the most inaccessible patches of the U.S. West and one of the largest roadless areas in the Lower 48, to float through that yawning canyon.

Why Conservation Matters: Rafting the Green River’s Gates of Lodore

By Michael Lanza

The momentarily sedate current of the Green River pulls our flotilla of five rafts and two kayaks toward what looks like a geological impossibility: a gigantic cleft at least a thousand feet deep, where the river appears to have chopped a path right through the Uinta Mountains of northeastern Utah. Sheer, cracked cliffs of burgundy-brown rock frame the gap. Box elder, juniper, and a few cottonwoods grow on broad sand bars backed by tiered walls that seem to reach infinitely upward and backward, eclipsing broad swaths of blue sky. A great blue heron stalks fish by the riverbank. We notice movement on river left and glance over to see two bighorn sheep dash up a rocky canyon wall so steep that none of us can imagine even walking up it.

These are the Gates of Lodore, portal to a canyon as famous today for its scenery and wilderness character as it was infamous for the catastrophes suffered by its first explorers, who set out in wooden boats a century and a half ago to map the West’s greatest river system.
