The canyons of the Teton Range lie almost entirely within Grand Teton National Park in the U.S. state of Wyoming. Ranging from 9 miles (14 km) to less than 1 mile (1.6 km) in length and up to 6,000 feet (1,800 m) deep, the canyons were carved primarily by glaciers over the past 250,000 years.[1] The canyons in the Teton Range descend in altitude generally west to east and many have lakes at their outlets. The lakes were created by terminal moraines left behind by the now retreated glaciers.[2] A few of the canyons have small glaciers that were created mostly during the Little Ice Age (1550-1850). Fast retreating Schoolroom Glacier is a tiny glacier located at the head of the South Cascade Canyon. Most of the canyons have streams from which rain and snowmelt flow towards Jackson Hole valley, and due to the sometimes rapid altitude descent, waterfalls are common. The canyons offer the easiest hiking access into the Teton Range.[3]
Teton Range canyons within Grand Teton National Park
Webb Canyon[4] is 9 miles (14 km) long and originates at several alpine lakes near the western boundary of Grand Teton National Park. Moose Creek flows through the canyon and empties into Jackson Lake.
Moran Canyon[8] is 6 miles (9.7 km) long and is situated south of Raynolds Peak, Traverse Peak and Bivouac Peak and north of Mount Moran. The canyon outlet is at Moran Bay on Jackson Lake.
Paintbrush Canyon[10] is 3 miles (4.8 km) long and the canyon outlet is near Leigh Lake. The popular but very strenuous Paintbrush-Cascade Loop hike traverses through the canyon.[3]
Cascade Canyon[12] is 7 miles (11 km) long and splits into the North Cascade and South Cascade canyons 4 miles (6.4 km) from its outlet at Jenny Lake. The canyon is more than 6,000 feet (1,800 m) deep in places as the north slopes of Mount Owen and Grand Teton tower above the canyon. One of the most visited canyons in Grand Teton National Park, Cascade Canyon can be accessed by trail via a loop hike around Jenny Lake or a boat shuttle which provides easier access to Inspiration Point and the nearly 200 feet (61 m) cascade known as Hidden Falls. Schoolroom Glacier is located at the head of the South Cascade Canyon while Lake Solitude lies at the end of the North Cascade Canyon.[3]
Valhalla Canyon[13] extends northward 1.5 miles (2.4 km) from the northwestern slopes of Grand Teton and ends within Cascade Canyon.
Garnet Canyon[14] is 2.5 miles (4.0 km) long and is the most commonly used canyon by mountaineers to access the upper slopes of Grand Teton, Middle Teton and other peaks of the Cathedral Group. The terminal moraine at the outlet of Garnet Canyon impounds Bradley Lake.
Death Canyon[16] is a popular hiking destination. More than 6 miles (9.7 km) long, the canyon provides access from Phelps Lake to the Teton backcountry region.
Granite Canyon[18] is the southernmost canyon in Grand Teton National Park. Granite Canyon is almost 6 miles (9.7 km) long and is flanked to the south by Rendezvous Mountain.
