Summary

A major flash flood at the Grand Canyon has left one person dead and approximately 15 missing or unaccounted for, with officials urging those with information about hikers or campers still missing to come forward. The flooding, which occurred on Saturday in Bright Angel Creek, forced evacuations and damaged a water pipeline that serves tourists and residents, prompting warnings about the limited potable water supply within the park. More than 60 people were airlifted from the canyon as a result of the flooding, with popular tourist spots including Bright Angel Campground and Phantom Ranch remaining closed while officials survey the damage. According to eyewitness accounts, the floodwaters were so powerful that they washed away footbridges and created new river rapids in the creek bed.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
