Lamar Valley View South

 The view south in the Lamar Valley towards Specimen Ridge in 1898 (A. Nelson, University of Wyoming Archives), and in 1970 and 1990 (D. B. Houston, Yellowstone National Park Archives). Researchers Doug Houston and Mary Meagher describe vegetation changes in the valley including the decline of big sagebrush and aspen near the arrow in the 1898 photograph.1 A current repeat photograph is required to evaluate additional ecosystem change since 1990.
