The Winthrop Glacier is a large glacier on the northeastern side of Mount Rainier in Washington. Named after Theodore Winthrop, the body of ice covers 3.5 mile² (9.1 km²) and has a volume of 18.5 billion feet³ (523 million m³).Cite web|title= DESCRIPTION: Mount Rainier Glaciers and Glaciations - Mount Rainier Glacier Hazards and Glacial Outburst Floods|publisher=USGS|url=http://vulcan.wr.usgs.gov/Volcanoes/Rainier/Glaciers/description_rainier_glaciers.html|accessdate=2007-11-19] Starting at over Convert|14300|ft|m|-2 at the Columbia Crest, the glacier heads north and descends steeply over the uneven topography of Rainier.Cite web|title=USGS Sunrise (WA) Topo Map|work=USGS Quad maps|url=http://www.topoquest.com/map.php?lat=46.88771&lon=-121.73751&datum=nad27&zoom=8|publisher=TopoQuest.com|accessdate=2008-05-15] Another glacier, the Emmons Glacier is directly connected to this glacier up to the Steamboat Prow. After passing the Prow, the glaciers split up; the Emmons heads east-northeastward and the Winthrop continues northeast. As the terrain becomes flatter, the Winthrop glacier becomes heavily rock-covered when it terminates in a forest at about Convert|4900|ft|m|-2|abbr=on|abbr=on. Meltwater from the glacier drains into the White 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 South Tahoma glaciers as well.
