Few photographers have documented America's public lands as extensively as Bob Wick. Last month, the Bureau of Land Management announced his retirement after 30 years of photographing our treasured public lands from Alaska to Arizona. As a federal employee, all of Bob Wick's photographs are all public domain, and his collection has been an invaluable resource to The Wilderness Society and other organizations around the country. As a tribute to Wick's incredible body of work, we wanted to share some of our favorites here.
