Story summary

On Saturday, flash flooding in Bright Angel Creek within the Grand Canyon claimed at least two lives: Dr. John Giusti, 46, from Granbury, Texas, and Brent Rosenkranz, 42; both were part of a group of three friends hiking through the area. A third friend, whose name is not specified but is described as 53 years old, remains missing. The flooding occurred after a wildfire last year made the mountainside water repellent, increasing flood risks. An alert system designed to warn officials when water levels rise dangerously was installed following that fire; however, it reportedly went offline during the event, raising questions about its effectiveness in warning hikers and rescuers. Search efforts for the missing friend are ongoing as of Tuesday.
