The Gros Ventre Slide Geological Trail is a 0.6 mile loop over rocks and debris left by the Gros Ventre Landslide. The mile wide Gros Ventre Landslide occurred in 1925 when 50 million cubic yards of debris came down Sheep Mountain and across the valley blocking the Gros Ventre River. This created Lower Slide Lake. The scar from the landslide off Sheep Mountain can easily be seen today from many miles away.

The trailhead for this hike is located east of the Mormon Row area. Travel on Gros Ventre Road for about 5 miles to reach the large parking area. Dogs are allowed on this trail when on a leash since this trail is not in Grand Teton National Park.

The trail winds its way through the debris that was pushed up on the north side of the valley. The trail is fairly easy to navigate as there are no big evaluation changes. About half way through the hike there is an obstructed view of Lower Slide Lake. Views of the scar on Sheep Mountain from the landslide can be seen while on this hike.
