2012 Map of Sylvan Lake

About this map

Sylvan Pass serves as a critical high-altitude corridor in this 2012 survey, where the roadway winds between Avalanche Peak and Hoyt Peak before descending toward the eastern edge of Yellowstone Lake. The landscape is defined by its dramatic vertical relief and complex drainage network, including the headwaters of Columbine Cr and Clear Cr. High peaks such as Grizzly Peak and Top Notch Peak dominate the skyline, while the southern portion of the map transitions into the Signal Hills and the geological curiosity of Brimstone Basin. This map captures the intricate relationship between the region's prominent summits, such as Mount Stevenson and Mount Doane, and the various glacial lakes, including the namesake Sylvan Lake and nearby Eleanor Lake. The layout of the modern highway through the pass illustrates the persistent path of travel dictated by these mountain gaps.
