Historic Photography Retake Project

James Hastings and Ray Turner's "Changing Mile" inspired George Gruell, the wildlife biologist for the Teton National Forest, to assess the condition and trend of wildlife habitat with repeat photography. His work, from 50 years ago, is the inspiration and foundation for this project.
