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

Young girls, camp employees and vacationers are among the at least 120 people who died when Texas' Guadalupe River flooded.

Almost a week has passed since fast-moving floodwaters tore through the Texas Hill Country during the early morning hours of July 4, submerging roads, sweeping away structures, and turning the usually peaceful Guadalupe River into a deadly force.
