1989 Map of Sylvan Lake

About this map

The high-elevation interface of Yellowstone National Park and the Shoshone National Forest dominates this provisional study, captured just years before the turn of the millennium. The landscape is defined by the Absaroka Range, where peaks like Mount Stevenson and Mount Doane overlook the Southeast Arm of Yellowstone Lake. Of particular interest to geothermal researchers are several designated Thermal Areas and the Brimstone Basin, illustrating the active volcanic nature of the region. The map highlights the primitive infrastructure of the wilderness, from the Thorofare Trail following the shoreline to the Sylvan Pass road. Small bodies of water such as Sylvan Lake and Eleanor Lake sit nestled between high summits like Avalanche Peak and Grizzly Peak, marking the drainage divides for Clear Creek and Columbine Creek.
