2023 Map of Ashnola Mountain OE N

USGS Topo · Published 2023

About this map

The northern boundary of the United States meets Canada in this high-altitude drainage basin within the Okanogan region. This 2023 survey focuses on the complex hydrography of the high country, where numerous unnamed tributaries form a dense dendritic network of mountain streams. The absence of roads, settlements, or structures reflects the protected wilderness character of the Forest Service lands in this remote section of Washington. For researchers, the map provides a contemporary baseline of the natural water systems and topography at the international border, showing the land exactly as it is managed by the Canada and United States authorities today.
