2020 Map of White Pass

About this map

White Pass Highway provides the primary access through this high-altitude landscape where the borders of Mount Rainier National Park, Gifford Pinchot National Forest, and Snoqualmie National Forest converge. The Pacific Crest National Scenic Trail winds north-to-south along the crest, passing notable mountain gaps like White Pass and Cowlitz Pass. This modern survey details the hydrological network of the Cascades, including the headwaters of the Bumping River and numerous alpine basins such as Twin Sisters Lakes, Leech Lake, and Sand Lake. The map illustrates the complex administrative geography of Lewis and Yakima counties, showing how the rugged terrain of Carlton Ridge and Tumac shaped historical travel corridors and modern conservation boundaries.
