Family members have identified more than a dozen people who are presumed missing after severe flooding in the Texas Hill Country on Friday.

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.

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