About this map

Manastash Lake sits at the heart of this high-elevation landscape, where the administrative boundaries of the Wenatchee National Forest and Mt Baker-Snoqualmie National Forest converge. The terrain is defined by dramatic ridgelines such as Manastash Ridge and the heights of Bald Mountain, punctuated by numerous water sources including Milk Lake and Cattle Camp Spring. This 1970s survey captures the region just as purple revision data from 1981 was integrated, showing the expansion of unpaved forest access routes like Barber Springs Road.

In the southern reaches, the Naches River cuts through the canyon floor along the border of Kittitas Co and Yakima Co. Remote landmarks like the Hog Ranch and Canteen Flats suggest a history of seasonal grazing and forest management. The presence of features like Devils Slide and The Island highlight the geological complexity of this section of the Cascades before later modern developments altered the primitive character of these backcountry drainage systems.
