The youngest girls at Camp Mystic in Texas were asleep in cabins as little as 225 feet from the river when flash flooding suddenly surged — causing the water to rise 20 feet above flood stage in just 90 minutes, starting around 4 a.m. on July 4.

Rescue teams continue their search after the Guadalupe River overtook cabins at Camp Mystic, a nondenominational camp in the Hill Country.

An eight-year-old girl and the director of an all-girls' summer camp are among the victims of flash floods in Texas that have claimed at least 51 lives, including 15 children. Officials say most of the victims have been identified. Authorities have not yet released any names publicly.
