About this map

Mount Jefferson dominates this high-altitude landscape in the central Oregon Cascades, where a massive glacial system feeds the headwaters of several major drainages. This 2011 survey documents the ice-bound topography of Russell Glacier, Jefferson Park Glacier, and Whitewater Glacier, alongside the Milk Creek Glacier and Waldo Glacier. These frozen fields give way to the meadows of Jefferson Park and Hole-in-the-Wall Park, illustrating the classic volcanic alpine environment.

Evidence of human presence is found primarily in named camp areas and high-country landings like Grizzly Flat and Hunts Cove. The complex hydrology of the region is centered on Pamelia Lake and several smaller alpine basins such as Bear Lake and Hunts Lake. Strategic high points such as Dinah-mo Peak, Goat Peak, and Bear Butte provide the primary landmarks for navigation through the dense drainage networks of the Whitewater River and South Fork Breitenbush River.
