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 were 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.

Camp Mystic was overrun by flash flooding that started on Independence Day. Rapidly rising waters ripped through the century-old all-girls Christian summer camp, killing at least 27 people. Others are still missing.

Gov. Greg Abbott surveyed the flood damage via helicopter Tuesday afternoon with Texas House Speaker Dustin Burrows.

Abbot said many of those who are not accounted for were staying in state’s Hill Country but did not register at a camp or hotel. He spoke at a news conference after taking a helicopter tour of the affected area.
