About this map

Gilbert sits at the junction of the mountain trails and the North Fork Twisp River, serving as a remote outpost in the high Cascades during the late 1960s. This survey, grounded in 1968 aerial photography and 1969 field checks, documents a landscape defined by mining history and high-altitude wilderness. The Crescent Mine and various Mines and Prospects scattered across the slopes of Gilbert Mtn and Abernathy Peak point to the area's mineral exploration legacy.

The map details a network of Pack Trail routes that provided the only access to interior features like Louis Lake and Bugger Lake. To the south, the boundary between Okanogan and Chelan counties crosses near Rennie Peak, descending toward the northern reaches of Lake Chelan. This geography illustrates the mid-century management of the Okanogan National Forest, balancing resource extraction with recreational sites like Roads End Campground.
