Jerry Mernin’s distinguished career in the National Park Service spanned four decades, five national parks, and a remarkable 32-year stay in Yellowstone, the park he loved and never left.

In his long-awaited memoir, Mernin takes readers behind the scenes to learn firsthand what it’s like to be a great park ranger. Along the way he shares a lifetime of exciting adventures, including dangerous rescues, remote backcountry patrols, and multiple heart-pounding encounters with grizzly bears.
