About this map

Olympic National Park serves as the backdrop for this topographic study, focusing on the icy crowning heights of the Olympic Peninsula. The three distinct summits—Mount Olympus West Peak, Mount Olympus Middle Peak, and Mount Olympus East Peak—anchor a radial drainage pattern where several massive ice bodies originate. The movement of the Blue Glacier, White Glacier, and Hoh Glacier defines the high-altitude landscape, feeding the headwaters of major coastal rivers.

Glacial retreat and hydrological shifts are evident in the relationship between these ice fields and features like Glacier Meadows and Elk Lake. Farther down the slopes, the terrain gives way to deep river valleys, notably the Hoh River and Queets River, which carry glacial melt toward the Pacific. High passes such as Glacier Pass and Blizzard Pass provide the only navigable breaks through the formidable terrain near Snow Dome.
