About this map

Jack Straw Basin sits at the heart of this high-altitude landscape where the borders of Gallatin County, Montana, and Teton County, Wyoming, converge. This 2020 survey illustrates a protected wilderness divided between the southeastern reaches of the Gallatin National Forest and the western edge of Yellowstone National Park. The terrain is defined by broad upland features like the Madison Plateau and Moose Creek Plateau, which drop off into a series of deeply incised drainages including Meadow Canyon, Echo Canyon, and Black Bear Canyon.

Hydrological features are sparse but significant in this arid mountain environment, with Big Bear Lake and the smaller Frog Pond providing permanent water sources. While mostly roadless, the presence of Plateau Rd in the northwest corner indicates the limited managed access into the Madison Valley backcountry. The map provides a precise record of the complex legal boundaries that define these public lands at the start of the 21st century.
