Two weeks after countries pledged their support to forests in Paris, Paula Swedeen and Joe Kane took a photographer and me for a hike in the Mount Rainier Gateway Reserve, a forest owned by the Nisqually Land Trust, of which Kane is the executive director. On our drive to the high reaches of the reserve we encountered a man named Donnie, who was on his way to the property’s ridgeline. Donnie wore jeans and a blue cotton sweater, an attire choice that grew more unfortunate as the falling snow accumulated.
