Maps show how heavy rainfall and rocky terrain helped create the devastating Texas floods that have killed more than 120 people.

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.
