The Grand Tetons Were Formed as a Result of a Seismic Event 

The Grand Tetons, a mountain range in western Wyoming, was formed due to a seismic event known as the Teton Fault. It’s a major geological fault that runs along the eastern base of the Tetons. It was created by tectonic activity along the boundary between the North American and Pacific Plates.

Around 9 million years ago, the land began to rise along the Teton Fault, creating a range of mountains that eventually became the Grand Tetons. Over time, erosion and glaciation have sculpted the mountains into their current form.

Today, the Grand Tetons are one of the most iconic natural landmarks in the United States, attracting millions of visitors yearly for hiking, camping, and other outdoor activities.

There Are 11 Active Glaciers in Grand Teton National Park

Ten glaciers have been previously named and can be found on U.S. Geological Survey maps: Teton, Middle Teton, Teepe, Schoolroom, Petersen, Falling Ice, Skillet, and East, Middle, and West Triple glaciers. There is one unnamed glacier near Glacier Peak.

However, some of these glaciers may have lost so much ice volume that they have stopped flowing and are no longer active glaciers.

You can see the Teton Glacier from the Teton Glacier turnout on the Teton Park Road. Look for the Falling Ice Glacier from the Mount Moran turnout and Skillet Glacier from Colter Bay area.

Moulton Barn

Mormon Row Was Established by Mormon Settlers

In the 1890’s, settlers from the Church of Jesus Christ of Latter-day Saints moved into the Jackson Hole Area from Idaho. At the time 27 homesteads were established here. Now only 6 homesteads remain standing.

In the 1990’s the cultural value of this settlement became more apparent and the park has since maintained the buildings so visitors can appreciate this fascinating past of Jackson Hole.

The two iconic barns at Mormon Row are the T.A. Moulton barn and the John Moulton barn. The T.A. Moulton barn (pointed roof) is south of Antelope Flats road, while the John Moulton barn (rounded roof) is to the north.

This is one of the best places to photograph Grand Teton National Park. The historic barns and homes here have one of the most scenic backdrops found anywhere in the world!
