Flash flooding in Texas Hill Country has triggered one of the largest rescue operations in the state’s history.

Crews search for victims of flooding that has killed almost 90 people in Texas Hill Country, with the risk of more flooding still high in central parts of the state. Authorities said Monday that the death toll was sure to rise.

Camp Mystic, the summer haven torn apart by a deadly flood, has been a getaway for girls to make lifelong friends and find “ways to grow spiritually.”
