Marble Falls, Texas
Marble Falls sits in Burnet County in the Highland Lakes region of the Central Texas Hill Country, about 38 miles northwest of Austin along the Colorado River. The city lies on Lake Marble Falls, one of a chain of reservoirs impounded along the river, and takes its name from a series of falls on the Colorado now submerged beneath the lake. The surrounding granite hill country, including the nearby dome of Granite Mountain, has long supplied stone used in Texas building.
