Strong storms claimed the lives of three members of a canyoneering party at Zion, and four others are missing. Here’s the latest from the National Park Service.

Three Canyoneering Fatalities, Four Others Missing in Zion National Park

Sept. 15, 2015

Rangers at Zion National Park in Utah received a report of a group of seven people canyoneering in Keyhole Canyon shortly before the flooding began Monday, Sept. 14. Their unoccupied vehicles were located on Monday evening and a search began the morning of Tuesday, Sept.15 when it was determined that these individuals had not exited the canyon.

Of the seven individuals involved, three fatalities are confirmed and the remaining four are missing. Names are not being released at this time, pending notification of kin. As the search continues for the missing hikers, high water levels and continued rain showers pose further flash flooding concerns and have hampered searchers’ access to the technical portions of the canyoneering route.

According to the National Park Service, storms arrived between 4:30 and 5:30 p.m Monday and dropped 0.63” in Zion Canyon in one hour. As a result of these local storms, flash flooding occurred in the park including Keyhole Canyon.

Keyhole Canyon is a short, narrow slot canyon located on the east side of Zion National Park. A permit is required for traveling through Keyhole Canyon and individuals must complete several short rappels under 30 feet and swim through several pools of water.
