But during winter’s coldest days, if the conditions are right, ice can form inside its deep, shadowy slot canyons, creating frozen pitches amid incredible red rock formations.

What they discover is a rowdy adventure of bushwacking and runouts, ice runnels and sandstone, snowfall and chimneys and, in the end, glorious ice.
