2023 Map of Boundary Dam

About this map

Harvey Grave sits on a high ridge in this remote corner of northeastern Washington, where the United States border meets the high peaks of the Colville National Forest. The landscape is dominated by the steep valley of the Pend Oreille River, which flows past dramatic features like Pewee Falls and the churning waters of Deadmans Eddy. The terrain is characterized by mineral-rich naming conventions, such as Dolomite Mtn, Limestone Hill, and the Lead King Hills, reflecting the area's geological and industrial history. Modern industrial footprints are visible near the southern edge at the Pend Oreille Mine Tailings Pond Dam near Grandview Point. Higher elevations transition into the protected Salmo-Priest Wilderness, where high-country lakes like Crater Lake and trails such as the Pacific Northwest National Scenic Trl traverse the Boundary Ridge.
