TheCathedral Group is the group of the tallest mountains of theTeton Range, all of which are located inGrand Teton National Park in theU.S. state ofWyoming. The Cathedral Group are classic alpine peaks, withpyramidal shapes caused byglacial motion. The highest peak in the group isGrand Teton, which rises more than 7,000 feet (2,100 m) aboveJackson Hole valley, and is the second tallest mountain in Wyoming, afterGannett Peak. The Cathedral Group is separated from other tall peaks of the range by theCascade Canyon to the north andAvalanche Canyon to the south.[1]
Half the remaining dozenglaciers in the Teton Range are located in this cluster of high peaks, including theTeton Glacier which is the largest one in the range. Other glaciers such as theMiddle Teton Glacier,Teepe Glacier, andSchoolroom Glacier are also located here. The Cathedral Group has several highcirques,arêtes as well ashanging andU-shaped valleys which are all the work of glacial activity. At the base of the Cathedral Group, severalglacial lakes can be found, includingJenny,Bradley andTaggart Lakes, all of which were formed when the glaciers of thelast ice age retreated, leaving behindterminal moraines which acted as natural dams. A few high altitude lakes can also be found scattered among the peaks.
In addition to Grand Teton, near the northern end of the group, other major peaks found here includeMount Owen,Middle Teton,South Teton,Teewinot Mountain,Teepe Pillar,Cloudveil Dome,Nez Perce Peak andBuck Mountain, most of which are over 12,000 feet (3,700 m) abovesea level and represent eight of the ten highest summits in the Teton Range.
Some geographers only include Grand Teton, Mount Owen and Teewinot Mountain as part of the Cathedral Group proper. Similarity of shape and isolation from other high peaks of the range by the deep Cascade and Death Canyons convince others to place all the major peaks between the canyons within the group.
