There is some debate among them as to what the "fresh" looking pile of rocks in the middle of the cirque represents. Consensus leans towards a relict rock glacier but an argument can be made that it is the terminal moraine (with ice at the core) of a small glacier that occupied the cirque during the Holocene. Strong evidence exists for active rock glaciers in the Uinta Range at similar aspects and elevations where more studies of glaciation occur, but even here, study is ongoing to prove that they are indeed active, and not relics.<br />One of the defining characteristics of a glacier (ice or rock) is movement, and to my knowledge, no movement has been documented in the ice or rocks in the Timpanogos cirque. Interestingly, the USGS Orem 62,500 quad from 1948 does map a glacier here, but whether this was mapped based on anecdotal evidence and aerial photos, or by a glacial geologists is unknown, I suspect the former. Pictures from the early 1900s do show crevices and deeper glacier-like features. This could represent the last gasp of a small glacier that formed during the little ice age (150-500 yrs b.p.), but I'm not aware of any documented movement of this ice.Richnoreply@blogger.comtag:blogger.com,1999:blog-6168620747792092240.post-26721038307694390302012-03-13T11:35:58.084-06:002012-03-13T11:35:58.084-06:00Yes, I think that's the case.

However, the Utah Geological Survey article states "whether or not glacial ice was ever present in recent historical time has not been rigorously documented, but is doubtful." Thus, even if it is on the map, there is some doubt about it actually being a glacier. We need to find us a geologist who can shed some light on this issue!Jim Shttps://www.blogger.com/profile/15799757451626876963noreply@blogger.comtag:blogger.com,1999:blog-6168620747792092240.post-34607402076635334212012-03-13T11:21:34.168-06:002012-03-13T11:21:34.168-06:00Dr Jim, I believe the USGS quad maps circa early 1...Dr Jim, I believe the USGS quad maps circa early 1950 named this feature a glacier.
