Starr County, Texas Map

Reading the Starr County map

The outline on this map is Starr County's legal boundary as published in the U.S. Census Bureau's TIGER/Line files. At 1,223 square miles, the county is roughly the size of a square 35 miles on each side — large enough that crossing it by car can take well over an hour. Straight survey lines on the map usually mark boundaries drawn by the legislature, while winding edges follow rivers and creeks.

The red marker shows Rio Grande 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.
