About this map

Rimrock Lake and the surrounding high-elevation terrain of the Snoqualmie National Forest dominate this topographical study in Yakima County. The settlement of Rimrock is situated at the eastern edge of the reservoir, near the infrastructure of the Rimrock Tunnel and the distinctive geological formation of Westfall Rocks. The map documents a landscape defined by significant elevation changes, with peaks such as Shellrock Peak and Ironstone Mountain rising above high-altitude grazing and transit areas like Strawberry Meadows and Cash Prairie.

Water management and recreation are central to the area's layout, evidenced by the numerous named inlets such as Silver Salmon Cove and Lonesome Cove along the lake's southern shore. A network of Forest Service roads, including Nat For Dev Rd 1382 and Tieton Reservoir Rd, provides access to these points and connects the reservoir to more remote features like the Wildcat Post Piles and the headwaters of Rattlesnake Creek.
