2019 Map of Rock Island

About this map

Rock Island serves as the focal point of this Colorado County landscape, situated along Alt 90 in a region characterized by expansive prairies and an intricate drainage network. The town's grid is clearly defined, with 1st St, 2nd St, and 4th St forming its core residential and commercial layout. Just south of the settlement, Myrtle Cem offers a primary point of interest for genealogists tracing local families. The surrounding terrain is dominated by Buzzard Prairie, where numerous seasonal water bodies like Prairie Lake and Black Lake dot the lowlands. This environment is shaped by the winding courses of Skull Cr, Crasco Cr, and Little Crasco Cr, illustrating the hydrological patterns of the Texas coastal plains. A network of rural roads, including Co Rd 106 and FM 102, connects the scattered ranching properties that define the area's agricultural character.
