2023 Map of Copper Mountain OE N

About this map

The northern reaches of Skagit County meet the international border with Canada in this 2023 survey. This landscape is defined by its deep hydrography, dominated by a large, elongated lake that stretches through the center of the quadrangle, fed by a dense network of mountain streams. The terrain analysis provided by the U.S. Geological Survey reveals the sharp vertical relief of the North Cascades, where the absence of roads or established settlements emphasizes the wilderness character of this borderland region. Mapping of this area relies on data from the National Hydrography Dataset and National Elevation Dataset to document the complex drainage patterns and high-elevation contours that characterize this portion of Washington.
