About this map

Marcelinas Hills rise above the surrounding Wilson County landscape, defining a rural Texas territory shaped by agricultural drainage and early energy exploration. The undulating terrain is bisected by the winding courses of Marcelinas Creek, Cibolo Creek, and Pajarito Creek, which create natural corridors for the small communities of Unity and Sunnyside. Industrial activity is localized but significant, centered on the Floresville Oil Field in the northwest and various gravel extraction points near the watercourses.

Evidence of historical transit and community life is anchored by the Old Railroad Grade and local landmarks like the Marcelina Ch and Wheeler Cem. The map reveals a high density of oil wells and pipelines integrated into the ranching and farming lands, illustrating the mid-century transition as the petroleum industry moved into traditional Texas hill country. These details offer a precise view of family holdings and the physical layout of the county before modern development shifted the character of these small settlements.
