Flash flooding struck the Grand Canyon area on Saturday, August 29, killing at least two people and leaving more than 20 others missing or unaccounted for. The National Park Service asked for public help locating the missing, and family members identified one victim as a Texas chiropractor; two men who were with him remained missing as of early September. The disaster highlights the danger of sudden, intense flash flooding in canyon terrain, where hikers can be caught with little warning. Search and recovery efforts were ongoing as officials worked to account for everyone reported missing.
