Supporters of Owen included The Wyoming Legislature and Paul Petzoldt, former pioneer American climber. Ironically among Langford’s supporters was Franklin Spalding, who led the ascent to the summit and tossed the rope that allowed Owen and the others to follow. The Teton Range in Grand Teton National Park rises nearly 7,000 vertical feet above the valley floor.
There’s no better an example of a fault-line mountain range in all of the Lower 48 states. The Teton Range, the youngest range in the Rockies, is the focal point of Grand Teton National Park, with its prominent peaks jutting some 7,000 feet into the sky from the surrounding valley. A renowned destination for climbers and mountaineers of all types, the Tetons have a lifetime of peaks and routes that range from easy to extreme, and plenty of undiscovered routes waiting for their first ascent.
The area around Jackson Lake, including national forest and other federal lands, were declared as a national monument in 1943. The park and monument were merged—and a 35,000-acre parcel was donated by John D. Rockerfeller, Jr.—to form the current Grand Teton National Park in 1950. The actual displacement between the two blocks of land that that formed the valley and mountain range goes much deeper. About 10 million years ago, Earth’s crust started to stretch and thin, forming faults and causing earthquakes.

Grand Tetons Facts
You’ll do the first 12 miles and 5,000 feet of gain to reach the saddle between the Middle and Grand Teton, while the remaining 2,000 feet of gain is done in just over a mile one-way. Part of the Grand Teton’s appeal is that it requires over 7,000 vertical feet of elevation gain to reach the top, meaning that you start at a fairly low elevation when you begin your climb. The Grand Teton is the crown jewel of the Teton Mountain Range in northwestern Wyoming. We recommend that you consult with a Visitor Center Park Ranger before hiking. The Teton Mountains are not only impressive due to their drastic rise directly from the valley floor, but also in their accessibility and the views their summits offer. The Operational Land Imager on the Landsat 8 satellite acquired this natural-color image of the park on June 15, 2015.
The ice sheet in many places in Jackson Hole exceeded 2,000 feet in thickness, and later glacial events eroded or covered parts of earlier ones. During the latest glaciations, ice flowed down canyons in the Teton Range onto the floor of Jackson Hole and built the moraines that dam Jackson, Leigh, Jenny, Bradley, Taggart, and Phelps lakes. Along the eastern base of the Grand Tetons are several clear blue lakes, the result of glacial moraine damming.

It is this dynamic of the west side of the fault rising while the east side falls that creates the magnificent rock monoliths that are the Grand Tetons. While many of the central peaks of the range are comprised of granite, the geological processes that lead to the current composition began about 2.5 billion years ago. At that time, sand and volcanic debris settled into an ancient ocean.
These inclusions have helped maintain the fame of the peak in the climbing community. Since the Grand Teton’s first ascent, 38 routes with 58 variations have been established. Grand Teton, at 13,775 feet , is the highest point of the Teton Range, and the second highest peak in the U.S. state of Wyoming after Gannett Peak. The mountain is entirely within the Snake River drainage basin, which it feeds by several local creeks and glaciers.
You’ll need to be self-sufficient on an unguided climb, and your pack will likely weigh far more than if you went on a guided climb. Guided climbs require less skill, but you should still be able to hike up six miles one way while carrying a 40-pound pack as well as basic mountain climbing skills. The Grand Teton has the most routes listed in the Fifty Classic Climbs of North America of any peak. The only other to have more than one route listed is El Capitan, with The Nose and Salathé Wall.
What Is The Lowest Elevation In Wyoming?
One of these dikes that slices through the face of Mount Moran is 150 feet wide—if the exposed part of the dike melted, the magma would fill Jenny Lake three times over! Black diabase dikes are also visible from the Teton Park Road on the east face of the Middle Teton and the southeast flank of the Grand Teton. Nathaniel P. Langford and James Stevenson claimed to have reached the summit on July 29, 1872. However, some believe their description and sketches match the summit of The Enclosure, a side peak of Grand Teton. The Enclosure is named after a man-made palisade of rocks on its summit, probably constructed by Native Americans. In all likelihood, The Enclosure was first climbed by Native Americans as suggested by Langford in 1873.
The direct start of the Exum Ridge using the Lower Exum Ridge Route (III, 5.7,) is considered a mountaineering classic and is featured in the historic climbing text Fifty Classic Climbs of North America. Grand Teton National Park supports a rich array of wildlife and stunning scenery, including the iconic, rugged mountain range that gives the park its name. Sometimes overlooked due to its proximity to Yellowstone National Park, Grand Teton is a hidden gem teeming with history, geologic mystery and majestic creatures. The Tetons are the youngest of all the mountain ranges in the Rocky Mountain chain. Most other mountains in the region are at least 50 million years old but the Tetons are less than 10 million and are still rising.
Look for moraines ringing glacial lakes such as Jenny, Taggart and Jackson, as well as some isolated moraines such as Timbered Island. The Tetons are one of the youngest mountain ranges in North America. They have been uplifting for less than 10 million years, making them “adolescent” mountains, as compared to the “middle-aged” Rockies (50-80 million years old) or the “elderly” Appalachians . Erosion has had much less time to work in the Tetons, comparatively, so their jagged peaks remain standing high.
Each movement of the fault—which has caused earthquakes in magnitude up to 7.5—has increased the offset between the mountains and the valley floor by five to 10 feet. The last major earthquake in the area was between 5,000 and 7,000 years ago, but geologists expect the fault will lurch again, jutting the peaks further into the sky. The Teton Range was set aside as a National Park in 1929 after decades of contention with local ranchers and other land interests. At the time, the park only included the Teton Range and glacial lakes at their base.
Lake Solitude is a ten mile hike up Cascade Canyon deep into the Grand Tetons but as you can see there isn’t much room for imporvement upon a scene like this. Archaeological studies reveal human presence in the area some 11,000 years ago. Prior to 1600 the inhabitants were Athabaskan-speaking Native Americans; later groups included the Shoshone, Crow, and Blackfoot.
Phelps, Jenny, Leigh, Sting and Jackson Lakes all have good fishing but some of the high lakes donêt have any fish in them so check before you invest any time. Jackson Lake has had a 52-pound lake trout harvested from its waters. Trout fishing in and around the Grand Tetons is a treat to all who give it a try. The Snake River is home to a unique subspecies of cutthroat trout known as the Fine-spotted Snake River Cutthroat Trout.
The naming of the mountains is attributed to early 19th-century French-speaking trappers—les trois tétons was later anglicized and shortened to Tetons. Table Mountain – Hiking to the top of Table Mountain is the perfect way to experience the Teton Range and the upper reaches of Cascade Canyon. A challenging trek, the trail to Table Mountain rises more than 4,000-feet in elevation in just 4.6 miles. However, the views from Table Mountain are arguably some of the best in the region and include Teton icons like Grand Teton, Middle Teton, South Teton, Cascade Canyon, Schoolroom Glacier, and Battleship Mountain. The Tetons are also a popular winter recreation destination, particularly for skiing, snowboarding, and mountaineering. In fact, in 1971, Bill Briggs, admirably named the “father of extreme skiing,” made the first-ever ski descent of Grand Teton and introduced the sport of ski mountaineering in North America.
