A Valencia man was among seven hikers overtaken by a flash flood Monday in Utah’s Zion National Park.

The park identified the hikers as Mark MacKenzie, 56, of Valencia; Linda Arthur, 57, of Camarillo; Steve Arthur, 58, of Camarillo; Robin Brum, 53, of Camarillo; Gary Favela, 51, of Rancho Cucamonga; Muku Reynolds, 59, of Chino; and Don Teichner, 55, of Mesquite, Nev.

Zion recorded 0.63 inches of rain and the North Fork of the Virgin River rose from 55 cubic feet per second to 2,630 cubic feet per second in 15 minutes.

On Monday, park rangers received a report of a group of seven individuals hiking in Keyhole Canyon shortly before the area flooded. The hiker’s unoccupied vehicles were located Monday evening and the search began on Tuesday morning when it was determined that the hikers had not exited the 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.

Extensive search efforts were not possible during the flooding or while the threat of flooding was still present.

The search lasted for three days. Steve Arthur, Favela, Reynolds and Teichner were located on Tuesday. Brum and MacKenzie were located on Wednesday.

As weather conditions improved in the park, rescuers were able to locate the last missing person, Linda Arthur, on Thursday.

“Our heartfelt sympathies go out to those affected by the flash flooding in Keyhole Canyon,” said Superintendent Jeff Bradybaugh. “We have witnessed an incredible community of the family members and friends of the canyoneers come together to support one another. The canyoneers along with their families and friends are in our thoughts.”

The families of the hikers extend their deepest gratitude for all of the Search and Rescuers and have also requested privacy during this difficult time.

During the Search and Rescue Operations, over 60 searchers from multiple agencies have contributed over 760 hours in their efforts to find the missing people.

Agencies assisting Zion National Park included Washington County Search and Rescue, Kane County Search and Rescue, Sanpete County Search and Rescue, Washington County Deputies, Town of Springdale, Rockville-Springdale Fire Protection District, Rocky Mountain Rescue Dogs, the Color Country Interagency Fire Center, Bryce Canyon National Park, Cedar Breaks National Monument, Glen Canyon National Recreation Area, Grand Canyon National Park and Grand Canyon-Parashant National Monument.
