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 narrows to the width of a doorway. A shallow, ice-water creek pumps along this slot canyon’s floor, which drops off before us about four feet into a pool extending some 30 feet ahead of us. We’ve been informed the water temperature is around 51° F. And it looks deep.
We’re going for a chilly swim.
