Published in anticipation of the 150th anniversary of the establishment of Yellowstone National Park in 2022, this book collects historic photographs, classic art, and an accompanying narrative that traces the history of the area from its Native American inhabitants to the present. Sidebars include profiles of the artists such as Thomas Moran who made the park famous, how the “subculture” of park employees has evolved over the years, the role of wildlife biologists in range management, as well as the ebb and flow of its large mammal populations as an increased human presence has put pressure on the Greater Yellowstone Ecosystem. Notwithstanding these challenges, the book is a celebration of the resilience of the place earlier visitors aptly called “Wonderland.” Jeff Henry was born in northern Pennsylvania, but has lived his entire adult life in and around Yellowstone National Park in southern Montana and northern Wyoming. He has worked various jobs in and around Yellowstone Park for the past 40 years, as fishing guide, wildlife researcher, tour guide, resource manager, park ranger, and winter keeper of the Park’s lodges. He is the author of Survive: Snow Country (Falcon, 2016) and The Year Yellowstone Burned (Taylor, 2015). Jeff lives with his daughter Mariah on the banks of the Yellowstone River in southern Montana.
