The '''Pyramid Glacier''' is actually a scattering of [[glaciers]] and snowfields located on the south-southwestern flank of [[Mount Rainier]] in [[Washington (U.S. state)|Washington]]. It covers {{convert|0.2|sqmi|km2|1}} and contains 400 million ft<sup>3</sup> (11 million m<sup>3</sup>) of ice.<ref name="USGS"/> The glaciers lie at an elevation ranging from about {{Convert|7000|ft|m|-2}} to {{Convert|9000|ft|m|-2|abbr=on}}.<ref name="TZ">{{Cite web|abbrtitle=onUSGS Mount Rainier West (WA) Topo Map|work=USGS Quad maps|url=http://www.topoquest.com/map.php?lat=46.82219&lon=-121.78957&datum=nad27&zoom=4|publisher=TopoQuest.com|accessdate=2008-05-17}}.</ref> The [[Success Divide]] separates this glacier from the [[South Tahoma Glacier]] to the west. Both the [[Success Glacier]] and lower end of the [[Kautz Glacier]] border this glacier on the eastern side.<ref name="TZ"/> Meltwater from the glacier drains into the [[Nisqually River]].<ref name="USGS"/>
 
In a June 2023 report from the [[National Park Service]], the glacier had lost 34% of its volume between 2015 and 2021.<ref>{{cite news |last1=Bush |first1=Evan |title=Three of Mount Rainier's glaciers have melted away |url=https://www.nbcnews.com/science/environment/three-mount-rainiers-glaciers-melted-away-rcna89123 |access-date=June 25, 2023 |work=NBC News |date=June 22, 2023}}</ref> Based on 2022 satellite imagery, glaciologist [[Mauri Pelto]] declared Pyramid Glacier dead.<ref name=ryan>{{citation |last=Ryan|first=John|title=Another three bite the dust: Heat melts Mount Rainier glaciers | newspaper=[[KUOW-FM|KUOW]] |date=June 13, 2023|url=https://www.kuow.org/stories/another-three-bite-the-dust-rip-3-mount-rainier-glaciers}}</ref>
