About this map

Frank Island stands as a prominent geographic feature within the southeastern waters of Yellowstone Lake in this 1980s-era topographic study. The map documents the intricate shoreline where the Southeast Arm meets the wilderness of Yellowstone National Park. To the east, the terrain rises sharply from the water's edge, marked by key navigation and landing sites such as Elk Point, Park Point, and Signal Point.

A network of drainage and transport is visible along the eastern shore, where Cub Creek, Clear Creek, and Meadow Creek flow into the lake. A designated Pack Trail winds through the shoreline forests, providing a rare inland route through this protected landscape. To the south, the massive landform of The Promontory divides the lake's southern reaches, while Plover Point and the Flat Mountain Arm anchor the southwestern corner of the quadrangle.
