Wildfire simulations were conducted at the regional scale to quantify the magnitude of predicted fire behaviors under various spatial and temporal conditions. The Texas Rangers and U.S. military patrols, which set up a frontier line of forts to protect the encroaching settlers, drove out or relocated all the Texas-native tribes by the end of the 19th century. The hills of the Hill Country formed when softer limestone eroded away from the harder granite and other rock beneath the surface. It became the 28th state of the union in 1845.
