The Olympic National Forest dominates this section of the Olympic Peninsula, where high ridges and deep river valleys define the timberlands of Grays Harbor County. The headwaters of several significant drainages emerge from the slopes, including the East Fork Humptulips River, the Wynoochee River, and the Wishkah River. Infrastructure in this heavy logging region centers on corridors like the Wynoochee Valley Road FH 203 and Donkey Crk/Grisdale, which connect the settlement of Grisdale and the Oxbow bend. A critical water management system is visible in the southern portion of the sheet, where the Wishkah Reservoir Number Two and the Aberdeen Reservoir serve as vital resources for the region. Prominent peaks such as Cougar Mtn and Humptulips Ridge stand above a network of forest development roads, illustrating the modern management of these Pacific Northwest highlands.
