 Other glaciers such as the Middle Teton Glacier, Teepe Glacier, and Schoolroom Glacier are also located here.The Cathedral Group has several high cirques, arêtes as well as hanging and U-shaped valleys which are all the work of glacial activity.At the base of the Cathedral Group, several glacial lakes can be found, including Jenny, Bradley and Taggart Lakes, all of which were formed when the glaciers of the last ice age retreated, leaving behind terminal moraines which acted as natural dams.
