About this map

Yellowstone Lake dominates this 1986 provisional survey, revealing the intricate shoreline of the West Thumb and the isolated landforms of Dot Island and Frank Island. The map documents a landscape defined by the water's edge, where specialized geological features like Sand Point and Rock Point mark the transition from the timbered uplands to the expansive lake surface.
