1963 Map of Sylvia Lake

About this map

The Lincoln Co Flathead Co boundary cuts through this high-country landscape, where the Kootenai National Forest meets the Flathead National Forest. This 1963 field-checked survey reveals a remote backcountry defined by steep ridges and fire-watch infrastructure, most notably the Lookout Tower atop Ingalls Mountain. Central to the quadrangle is Sylvia Lake, situated near a small Roadside Park, serving as a rare point of developed access in a region otherwise navigated by an extensive network of Pack Trail routes. These trails follow the drainages of Sheppard Creek, Ingalls Creek, and the South Fork Hand Creek, providing a detailed look at the montane environment before more modern road development reached these higher elevations. The map also identifies prominent peaks including Mount Conner, Sanders Mountain, and Grubb Mountain.
