Granite Mountain, a pink-granite dome one mile west of Marble Falls in central Texas, was a steep-sided bornhardt that originally rose more than 860 feet. Its Sunset Red stone became significant to Texas construction after quarrying began in the late nineteenth century. In 1882, owners G. W. Lacy, N. L. Norton, and W. H. Westfall donated granite from the mountain for the Texas State Capitol in Austin, and the same distinctive rock was also used for the Galveston Seawall. Extensive quarrying later transformed the site so completely that it no longer appears as a natural mountain.
