2011 Map of Fossil Lake

About this map

Big Moose Resort sits near the southwestern edge of this high-elevation landscape, where the Beartooth Plateau's complex alpine hydrology is on full display. The area is defined by a dense concentration of glacial lakes, many with descriptive or whimsical names like No Bones Lake, Pneumonia Lake, and Fizzle Lake. These water bodies are surrounded by prominent peaks including Mount Dewey and Mount Rosebud to the east, and Oxide Mountain near the center. The map reveals a land characterized by sheer granite features like Rock Island Butte and the vast waters of Upper Aero Lake. This 2011 survey serves as a detailed record of the drainage patterns and peaks in this remote mountain environment, where naming conventions often reflect the challenges of early exploration and survey work.
