About this map

Bridger National Forest and the Bridger Wilderness dominate this high-altitude landscape in the Wind River Range, where high meadows and alpine lakes dictate the paths of early travel. The survey area centers on the Big Sandy River, tracing its course through the Lamreaux Meadows and past the Big Sandy Campground. The map reveals a complex network of pack trails and jeep tracks, such as the Pack Trail and Driveway Jeep Trail, which served as the primary conduits through the drainage systems of Dutch Joe Creek and Muddy Creek.

Glacial features are prominent across the terrain, from the heights of Laturio Mountain to the clustered waters of Mirror Lake, Fish Lake, and Boulder Lake. To the south, the topographic character shifts toward Muddy Ridge, while deeply cut features like Irish Canyon illustrate the erosive power of the seasonal runoff. This survey provides a look at the backcountry infrastructure of the late 1960s, documenting the specific meadow systems and lake groups used by generations of recreationists and wilderness managers.
