North Cascades National Park defines the high-altitude landscape of this Whatcom County survey, where the international boundary meets a jagged collection of summits and glacial drainages. Mount Spickard and Mount Rahm anchor the western terrain, flanking the prominent Custer Ridge and the high waters of Silver Lake. The map details a complex network of alpine watersheds, including the headwaters of Little Beaver Creek and the southern flow of Silver Cr as it moves toward the Ross Lake National Recreation Area. These drainages, such as Redoubt Cr and Perry Cr, cut deep through the land, illustrating the natural barriers that have preserved this region as a protected wilderness. The absence of roads or permanent human settlements emphasizes the primary role of the landscape as a conservation and recreation corridor at the edge of the Canadian border.
