1985 Map of Lone Tree

About this map

The North Fork Payette River feeds the expanse of the Cascade Reservoir along the eastern edge of this mid-1980s survey, marking a significant hydrologic divide in the West Mountains. To the west, the drainage shifts toward the Weiser River basin, defined by the Middle Fork Weiser River and the Little Weiser River. This transitional landscape is managed as part of the Payette National Forest and Boise National Forest, with the boundary between Adams and Valley counties running through the high ridges. Local topography is detailed through named summits and water features such as Mica Hill, Poison Lake, and the distinctive Lone Tree landmark. The intricate network of seasonal and perennial streams, including No Business Creek and White Licks Creek, illustrates the complex watershed that characterizes this high-elevation region of central Idaho.
