Rescue operations are ongoing in Central Texas after flash flooding along the Guadalupe River left 23 girls from Camp Mystic unaccounted for. Officials say dozens have died as catastrophic floods continue to ravage the Hill Country.

Generations of the same family have operated the summer camp since 1939. It counts family members of former president and governors as alumnae.
