About this map

Rimrock Lake dominates this high-altitude landscape, its shoreline defined by the impoundment of the North Fork Tieton River and South Fork Tieton River. The Tieton Dam regulates these waters at a spillway elevation of 2,922 feet, supporting a recreation-focused environment that includes several boat ramps and the Indian Creek Campground. This 1967 survey, later photorevised to reflect 1983 conditions, illustrates the transition between the managed waters of the reservoir and the protected high country of the William O Douglas Wilderness.

Away from the water, the terrain rises sharply toward prominent summits like Shellrock Peak and Ironstone Mtn. The map tracks the drainages of numerous creeks, including Rattlesnake Creek and Wildcat Creek, which carve through the Mt Baker - Snoqualmie National Forest. Practical infrastructure such as the Tieton Emergency Airstrip and scattered borrow pits sit alongside landmarks like Westfall Rocks, documenting the area's dual role as a wilderness and a managed resource.
