View from Cascade Pass, at the northern end of the traverse. Beyond Cascade Pass the route is a challenging, trail-less mountaineering endeavor.
A portion of the southern Ptarmigan Traverse, looking east: route climbs the LeConte Glacier (left edge of photo), traverses around the west side of Sentinel Peak (dark pyramidal peak, left-center), descends to the South Cascade Glacier (center), ascends to ridge at top of the glacier (right-center), and crosses over to the White Rock Lakes.
Dome Peak at the southern end of the traverse

Ptarmigan Traverse is an alpine climbing route in the North Cascades of Washington state. The route, from Cascade Pass to Dome Peak, is generally remote, unmarked, and challenging, traversing rugged terrain and several glaciers.
