A few years ago, after suffering a mental health crisis during a mountaineering expedition, National Geographic photographer Cory Richards walked away from his climbing career. In 2016, after a terrible rafting accident, Outside writer Katie Arnold nearly ended her marriage. This summer, they are both telling their stories in powerful new books. In The Color of Everything, Richards describes using the body to heal the mind. In Brief Flashings in the Phenomenal World, Arnold talks about using the mind to heal the body. They spoke with contributing editor Florence Williams at The Outside Festival, in Denver.
