How was Emmons Glacier formed?
The debris avalanche deposit is the remnant of a landslide of rock that tumbled down the slopes of Mt. Rainier onto the Emmons Glacier and the valley beneath the glacial terminus. The lake formed after the glacier retreated – it is a moraine-impounded lake. The lake is unstable.

What is the gradient of the Winthrop glacier near the summit?
35-40 degree
This is a smooth, wide tract (approximately 30 degrees) that ascends towards the summit. This aspect of the climb ends at approximately 11,200 feet. Upon exiting the corridor, traverse to the right on 35-40 degree slopes and skirt the summit cap.
What is the easiest route up Mt Rainier?
Disappointment Cleaver
Disappointment Cleaver This is the easiest route on the mountain — and by far the most crowded. The Cleaver gets 75 percent of Mt. Rainier’s traffic.
What glacial feature is Sunset Amphitheater?
Sunset Amphitheatre: Chiseled and dredged by rockslides, glacial erosion, and frost action, Sunset Amphitheatre is a cirque- like gouge near the summit of the mountain. Puyallup Glacier originates in Sunset Amphitheatre.
How did glaciers form on Mount Rainier?
Another way glaciers have shaped Mount Rainier is by the interaction of ice with volcanic eruptions. Evidence from the margins of cooled lava flows below Paradise Glacier indicate that during major ice ages, erupting lava would flow along the margins of glaciers or in meltwater trenches on the glacier.
In which compass direction is Winthrop glacier flowing?
After passing the Prow, the glaciers split up; the Emmons heads east-northeastward and the Winthrop continues northeast.
Is Mt Rainier a glacier?
Mount Rainier, Washington, at 14,410 feet (4,393 meters), the highest peak in the Cascade Range, is a dormant volcano whose glacier ice cover exceeds that of any other mountain in the conterminous United States.
