Backbone Valley Blanco County Pioneer Strongbox — Blanco County

Joseph Bird established Birdtown, now Round Mountain, in 1854 in northern Blanco County. The northern and central parts of the county drain into the Colorado River through Miller Creek, Cypress Creek, and the Pedernales River. Early Blanco County was carved from parts of Comal, Hays, Burnet, and Gillespie counties in 1858; northern upland settlers clustered along wooded divides that local land descriptions sometimes called backbone country.
