Here's what to know about the deadly flooding, the colossal weather system that drove it and ongoing efforts to identify victims.

The camp, which was established in 1926, has experienced a long history of flooding from the Guadalupe River, leading to multiple evacuations and damages across the campgrounds, according to CNN. The July 4 flood was the most damaging disaster in the area, followed by a flooding in 1987 in which 10 children at a different camp nearby were killed.

Days after flash floods killed over 100 people during the July Fourth weekend, search-and-rescue teams are using heavy equipment to untangle and peel away layers of trees, unearth large rocks in riverbanks and move massive piles of debris that stretch for miles in the search for the missing people.
