About this map

Pinegrass Ridge dominates the high-country landscape of the Cascades in this late-1980s provisional survey of Yakima County. This area represents a protected intersection of alpine hydrology and forest management, where the Goat Rocks Wilderness meets the broader Snoqualmie National Forest. The network of drainages is remarkably dense, anchored by the North Fork Tieton River and feeding prominent water bodies such as Hell Lake, Clear Lake, and the sequestered Phantom Lake.

Evidence of high-elevation land use appears in the various Corral and Gate markings found near Conrad Meadows and Tieton Meadows, suggesting seasonal grazing or back-country management. Topographical landmarks like Bear Creek Mountain and the ominous Devils Horn define the western reaches of the quadrangle. For the researcher, the inclusion of remote features like the Devils Washbasin and numerous creeks such as Scatter Creek and Miriam Creek provides a definitive record of this drainage basin before modern ecological shifts.
