About this map

The Colorado River and the sprawling waters of Lake Lyndon B Johnson anchor this detailed study of the Texas Hill Country, where the boundaries of Llano, Burnet, and Blanco counties meet. The landscape is defined by its transition from high granite outcroppings like Packsaddle Mtn and Dunman Mtn to the modern residential development of Horseshoe Bay and Sunrise Beach Village. For genealogists, the map preserves the locations of several rural burial grounds, including Wolf Crossing Cem near the Burnet County line and Pecan Creek Cem to the south.

Local history researchers can trace the intricate network of ranch roads and hollows, such as Ship Hollow and Hogpen Hollow, that reveal the area's agricultural and topographical character. The presence of the Sunrise Beach Airport and the expanding street grids of Granite Shoals and Highland Haven contrast with the creek beds of Sandy Creek and Pecan Creek, illustrating the late-20th-century evolution from ranchland to a prominent lakeside community.
