2011 Map of Jack Straw Basin

About this map

The Madison Plateau dominates this high-elevation landscape, where the Jack Straw Basin sits as a central drainage feature within the Gallatin County wilderness. The area is characterized by its high-altitude water features and complex topography, notably Big Bear Lake in the southeast and the smaller Frog Pond tucked along the western edge. A sparse network of forest service roads, including the primary Plateau Rd and FS 1700, provides the only access through this rugged territory. Human presence is minimal, anchored by the South Riverside Cabin near the southern boundary. Steep geological transitions are marked by Echo Canyon and Meadow Canyon, which carve through the plateau's edges. This 2011 survey captures the area's undeveloped character, preserving the exact layout of backcountry routes and remote landmarks used by researchers and wilderness travelers.
