Lyndon B. Johnson National Historical Park is composed of two separate districts (the Johnson City District in Blanco County and the LBJ Ranch District in Gillespie County), each lying in the Pedernales River Valley, which cuts through a geologic region known as the Llano Uplift. The area is characterized by hills covered with ashe juniper and various species of oak. Elevations range from 1,000-2,500 feet above sea level.
