2023 Map of Ashnola Pass OE N

USGS Topo · Published 2023

About this map

Canada forms the northern boundary of this topographic study, where the northern reaches of Okanogan County meet the international border. The landscape is defined by an intricate network of drainages and high-altitude watercourses that flow southward from the boundary line. This high-country terrain, captured in 2023, reflects a primary focus on the natural hydrography and elevation of the northern Cascades. While human-made structures and named settlements are absent in this specific quadrangle, the precise mapping of the Canada border provides a clear reference for those studying transboundary watersheds or the remote geography of the Pacific Northwest.
