His life changed in an instant when an avalanche hit them, killing his best friend Steve. For years afterwards, Joe's life was characterised by anxiety, depression and post-traumatic stress disorder. But with friendship, photography and an unwavering love of the wilderness, Joe found healing and peace in the Chugach again.
