South Tahoma Glacier : ウィキペディア英語版 | South Tahoma Glacier
The South Tahoma Glacier is a glacier located on the southwest flank of Mount Rainier in State of Washington. It covers and contains 4.6 billion ft3 (130 million m3) of ice.〔 Starting from an elevation of around at the base of a steep cliff, the glacier flows down southwest with the larger, adjacent Tahoma Glacier lying to the north. The smaller South Tahoma is connected to the Tahoma at an ice patch located in midway down the South Tahoma. From then on, the glacier narrows and flows down southwest and accumulates rock debris before turning and ending at an elevation of around . The southern ice stream used to be connected to a northern ice stream coming down south from the Tahoma Glacier encompassing a jagged high sub-peak of Rainier called Glacier Island, but retreat has separated the glaciers at an elevation below .〔 Meltwater from the glacier drains into the Nisqually River.〔 ==Debris flows== The glacier is one of four on Mount Rainier that are known to have released debris flows. Similar flows have stemmed from the Nisqually, Kautz, and Winthrop glaciers as well. The glacier has at least 23 recorded debris flows since 1967, with 15 reported between the years 1986 and 1992. The floods have caused damage and disruption to the roads and picnic areas downstream.〔 In August 2015, a debris flow was caused by a glacial outburst flood when meltwater was released by the glacier. Part of the Westside Road was damaged by the debris flow.
