About this map

The eastern shore of Flathead Lake is defined by the steep rise of the Mission Range, where numerous seasonal drainages like Talking Water Cr and Boulder Cr cut through the high-elevation contours toward the water. This 2020 topographical study captures the complex interface between the deep lake and its rocky coastline, highlighting the distinct landforms of Finley Point and the passage known as The Narrows.

Residential development is concentrated along the shoreline, connected by E Shore Rd and local access ways such as Evening Star Ln and Siedentopf Ln. Off-shore, the isolated landmasses of Bull Island and Bird Island provide navigational reference points within the lake. The map illustrates a landscape shaped by glacial history, where numerous inlets like Yellow Bay and Skidoo Bay create a jagged, protected coastline south of the Mission Range foothills.
