Torrential rains before dawn on Friday deluged the Guadalupe River, which burst its banks and killed dozens of people, leaving behind mangled piles of debris, trees and cars.

Rescuers searched the Guadalupe River for survivors of the Texas floods that killed more than 100 people over the July Fourth holiday weekend, with an unknown number of people still missing. The basin area was crowded with families and campers preparing to enjoy the holiday when pounding rain brought about catastrophic flash floods just before dawn Friday.
