2020 Map of Castle Peak OE N

About this map

The international border with Canada defines the southern edge of this remote wilderness area, which sits within the northernmost reaches of the Mount Baker National Forest. This 2020 survey records a landscape shaped by a dense network of high-altitude drainages and tributaries, many of which remain unnamed on this specific sheet. The lack of roads or established settlements on this map underscores the wild nature of the North Cascades during this era, serving as a clean record of the region's natural hydrography and terrain before any future human infrastructure or major forest management changes. It is a focused study of the drainage patterns flowing north into British Columbia and south toward the heart of the national forest.
