In her luminous inquiry into the intricate connections among work, place, and people, Frieda Knobloch explores the lives of two Rocky Mountain botanists, Aven Nelson (1859-1952) and Ruth Ashton Nelson (1896-1987). Aven was a professor of botany at the University of Wyoming for many years; Ruth compiled field guides to Rocky Mountain plants and wrote articles on botany for magazines. The two met and married when Aven was in his seventies and Ruth was in her mid thirties, and they developed a symbiotic partnership that joined work and play, learning and companionship. Into this relatively straightforward reconstruction of two lives Knobloch blends the history of her own life as a scholar and an amateur naturalist, her own journal entries, and her letters written to Ruth to create a transformative environmental auto/biography.
