The bodies of two friends — a Texas chiropractor and a martial arts studio owner — have been found after a major flash flood swept through the Grand Canyon. Officials said Monday that one person remains unaccounted for after about 80 others were rescued over the weekend. Park officials did not release identities, but the families of the two deceased men identified them as John Giusti and Brent Rosenkranz. THey say their buddy Saturday’s flash flood severely damaged the only water pipeline into the canyon. Officials have barred tourists from staying at lodges and hotels inside Grand Canyon National Park and issued emergency water restrictions for year-round residents. Officials say they used the park’s permit system to track the number of missing people.

The sole pipeline that supplies water for millions of Grand Canyon visitors was badly damaged by weekend flash flooding, setting up a tricky repair scenario and upending a yearslong construction project to upgrade the line. The Transcanyon Waterline traverses terrain so rugged that helicopters are often required to make basic repairs. Park officials say roughly 40% of the 12.5-mile-long line was damaged or destroyed. It has endured dozens of breaks in recent years and was undergoing a more than $200 million repair and replacement project when the floods hit. The rugged terrain makes any effort to fix breaks time-consuming, precarious and costly, so efforts to address the latest damage will be complicated.

Tourists are scrambling to find lodging elsewhere after deadly flash flooding in the Grand Canyon. A damaged water line shut down all lodging at the canyon’s South Rim. As of Tuesday it's unclear when lodging might reopen. The park remains open to daytime visitors but the natural disaster threatens the area’s economy. South Rim restaurants are open, but experts warn that lost room bookings could cost hundreds of thousands of dollars in local revenue. The Grand Canyon drew almost $1 billion a year in spending by nearly 5 million tourists in 2024. Last summer, a wildfire destroyed a lodge and eliminated lodging options at the canyon’s North Rim.
