The Tahoma Glacier is a long glacier mostly on the western flank of Mount Rainier in Washington. It covers 1.2 square miles (3.1 km2) and contains 4.3 billion cubic feet (120×106 m3) of ice. The glacier starts out near the summit of the volcano at over 14,200 feet (4,300 m). As the glacier flows west-southwest out of the summit area, it cascades down a steep rocky face as an icefall from 13,200 feet (4,000 m) to 11,000 feet (3,400 m), where the glacier is connected to the South Mowich Glacier to the north in the Sunset Amphitheater. As the glacier drops below 10,000 feet (3,000 m), it broadens and joins the smaller South Tahoma Glacier. After the broad expanse of ice at over 8,000 feet (2,400 m), the Tahoma Glacier narrows as it descends around the rocky 7,690-foot (2,344 m) Glacier Island
