The following is a news release from Grand Teton National Park.
MOOSE, Wyoming — The National Park Service has implemented an emergency closure in the Hidden Falls and Inspiration Point areas on the west side of Jenny Lake for human safety. Some recently expanding cracks and fissures have been identified in a large rock buttress above the Hidden Falls viewing area.
Superintendent David Vela said, “Human safety is our number one priority, and with an abundance of caution we are temporarily closing this area until we can properly assess the situation.”
Those familiar with the site, specifically park rangers and personnel with Exum Mountain Guides, identified the cracks and fissures and determined the situation to be a possible safety hazard. The notable changes in the rock over the past 24 hours spurred park rangers to implement a temporary closure and initiate a risk assessment with subject-matter experts.
Exum Mountain Guides are relocating their practice school services to another location, and shuttle boat and scenic cruises with Jenny Lake Boating will continue to operate. Visitors are able to ride the boat to the west shore, hike Cascade Canyon or around the lake, and enjoy some areas of the west shore as well as the front country areas of the Jenny Lake Complex.
It is unknown how long the closure at Hidden Falls and Inspiration Point areas will be in place.
