At Camp Mystic, a Christian summer camp in Hunt, Texas, where officials are grieving the loss of 27 children and counselors, belongings of the young campers are strewn about the flooded floors of a dormitory, while other items, including a pink backpack and a Camp Mystic t-shirt, were found along the bloated Guadalupe River, photos show.

Rescuers were scouring a devastated central Texas landscape of mangled trees, overturned cars and muck-filled debris on Sunday in an increasingly bleak mission to locate survivors following a historic flash flood.
