Rock Island serves as the central hub of this South Texas landscape, where the town grid is defined by streets like Lupton St, Cushen St, and 2nd St. The settlement is situated along the Alt 90 corridor, south of the open expanse of Buzzard Prairie. The surrounding terrain is a network of slow-moving coastal plain waterways, with Crasco Cr and Little Crasco Cr draining the northern reaches, while Pinoak Cr and Bucksnag Cr wind through the south. This 2022 survey captures the modern rural layout of Colorado County, where established landmarks like Myrtle Cem and water features like Black Lake and Prairie Lake provide historical continuity. The map highlights a transition from traditional agricultural lands toward residential developments on the eastern edge near Deer Run Rd.
