In this remarkable collection of photographs, Fritz Mueller captures fleeting, compelling moments in a timeless Yukon landscape, one of the world's wildest and most overlooked wilderness areas. The view through Mueller's lens is influenced by his scientific roots and inspired by his visual artist's aesthetic. Mueller takes readers on the annual migration of the Porcupine caribou herd, and he captures intimate portraits of icy grizzly bears gorging on salmon at the Arctic Circle. Mueller crosses sprawling glaciers and navigate Yukon's clear mountain rivers. His appreciation for nature's minutiae — voles, berries, frogs — is a refreshing perspective on a landscape writ large. Complemented by evocative text by Teresa Earle, this book is a celebration of all things wild, from vivid northern lights to enchanting landscapes to elusive wildlife. As wilderness vanishes and intact ecosystems deteriorate, the Yukon remains one of the last wild hot spots, a conservation treasure of international significance.
