1999 Map of Straight Peak

About this map

The Bitterroot Mountains define the high-altitude divide on this late 20th-century survey, marking the state border where Montana Idaho meet. This terrain is characterized by a high density of alpine water bodies, including the Trio Lakes, Hidden Lake, and the geographically central Heart Lake. The landscape is managed as part of the Lolo National Forest and Clearwater National Forest, where the topography drops sharply from summits like Straight Peak and Lightning Peak into narrow drainages such as Fletcher Gulch and Snowy Gulch. The complex network of water features, from Crater Lake to the headwaters of South Fork Trout Creek, illustrates a pristine wilderness environment before the turn of the millennium. Surveyed boundaries for Mineral, Shoshone, and Clearwater counties intersect here, reflecting the remote nature of these political divisions in the high backcountry.
