Blanco County, Texas Map

Reading the Blanco County map

The outline on this map is Blanco County's legal boundary as published in the U.S. Census Bureau's TIGER/Line files. At 711 square miles, the county is roughly the size of a square 27 miles on each side — small enough to cross in a short drive. Where the border is a ruler-straight line, it was set by survey; where it wiggles, it usually follows a river, creek or old land grant.

The red marker shows Johnson City, the county seat, and the highlighted shapes in the schematic view are the bordering counties. Use the layer switcher to change between street, satellite and terrain backgrounds: satellite is best for seeing farmland and development patterns, while terrain shows hills, valleys and river corridors.
