In the refrigerator-like shade at the bottom of a fissure hundreds of feet deep, somewhere in the labyrinth of sandstone canyons that dice up the backcountry of Zion National Park, our keyhole-shaped passageway narrowed to the width of a doorway. A shallow, ice-water creek pumped along the slot canyon’s floor, which dropped off before us about four feet into a pool extending some 30 feet across. We’d been informed the water temperature was around 51° F. And it looked deep.
We were going for a chilly swim.
