The Liberty Cap Glacier is a small glacier located near the summit of Mount Rainier, Washington. True to its name, the glacier does start at the 14,100 feet (4,300 m) Liberty Cap above the steep and rocky Sunset Amphitheater and the Mowich Face.[1][2] Since the topography of Mount Rainier is very jagged and uneven, the glacier is warped and twisted during its descent northward down to its terminus at about 11,000 feet (3,400 m). From there, the glacier ice falls off the cliff and tumbles down the steep Mowich Face; eventually, this ice contributes to the large North Mowich Glacier at an elevation of 10,100 ft (3,100 m).[2]
Climate
Liberty Cap has an ice cap climate (Köppen EF).
