2024 Map of Jack Straw Basin

About this map

Yellowstone National Park and Gallatin National Forest converge at the high-altitude border of Montana and Wyoming on this sheet. The landscape is defined by the sharp transition between the Madison Valley and the sprawling Madison Plateau, featuring a network of deep drainages such as Echo Canyon and Black Bear Canyon. The namesake Jack Straw Basin sits centrally, reflecting a remote wilderness area where high ridges separate the Gallatin and Teton county lines. Localized water features including Big Bear Lake and Frog Pond provide points of reference within the heavily forested and canyon-scored terrain. The map's layout illustrates the complex topography of the Moose Creek Plateau, revealing the intricate drainage patterns that flow through Dry Canyon and Meadow Canyon toward the valley floors.
