“As geologists, we may be rational scientists, but expeditions to remote places touch something deep in us that moves us to also be poets. Glassley has turned his experiences in Greenland into searingly beautiful descriptions of a wild landscape and the ways in which that landscape moves and changes him. Every sentence is evocative, connoting curiosity, awe, and respect in equal measure. A Wilder Time is a paean on the importance of wilderness to the human spirit and a saddening reminder of what we lose when we divorce ourselves from contact with wild places. Glassley’s voice will stay with me the way the works of Loren Eiseley, Edward Abbey, Rachel Carson, and Aldo Leopold have stayed with me over the decades.”
