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.

The search for unlikely survivors grew more desperate four days after one of the deadliest U.S. floods in decades. Ten campers and a counselor are among those still missing.
