Climate change is impacting hiking on the infamous Pacific Crest Trail

Wildfires closed more than 600 miles of the Pacific Crest Trail, forcing hikers off the path.

The Pacific Crest Trail, or PCT, runs all the way from the U.S. border with Mexico to the border with Canada, crossing more than 2,600 miles of desert, mountains, and forest. And for many people, hiking the trail end to end is a lifelong goal.
