1963 Map of Sonny Boy Lakes

About this map

Hidden Lake Lookout stands as a prominent sentinel above the high-elevation terrain of the Mt Baker National Forest during the early 1960s. The landscape is defined by the complex drainage of the Cascade River, where the North Fork Cascade River and South Fork Cascade River converge amidst a network of glacial lakes and steep ridges. The limited human footprint in this wilderness is represented by the Cascade River Road and the Mineral Park Campground, which provided access for early recreation and forest management. High-altitude features like the Sonny Boy Lakes, Hidden Lake, and the curiously named Long Gone Lake illustrate the alpine character of the region. The mapping of Hidden Lake Peaks and Kindy Ridge reflects the detailed photogrammetric work of the era, capturing the high-relief topography before later changes in forest designations.
