About this map

Mount Rainier National Park dominates this early 1970s topographical study, revealing a complex network of high-elevation routes and landmarks within the eastern reaches of the park and Snoqualmie National Forest. The landscape is defined by the convergence of major mountain passes, including Chinook Pass and Cayuse Pass, which serve as critical transit points through the Cascade crest. Notable human infrastructure is integrated into the wilderness, such as the Shriner Peak Lookout Tower and the Nickel Creek Shelter, reflecting the managed recreational use of the era.

Glacial features like the Sarvent Glaciers sit adjacent to high-altitude water bodies including the Owyhigh Lakes and Tipsoo Lake. The map details specific preservation and access sites, from the ancient trees of the Grove of the Patriarchs near the Stevens Canyon Entrance to the expansive The Burn in the south. Extensive hiking infrastructure is meticulously documented, showing the path of the Wonderland Trail as it winds through rugged drainages like the Ohanapecosh River and Chinook Creek.
