The community of Alum sits at the center of this rural South Texas landscape, defined by a network of creeks and drainage branches that carve through Wilson County. Tributaries such as Alum Cr, Clifton Br, and Steel Br converge toward the larger Ecleto Cr drainage system. The settlement patterns are documented through a series of local county roads and farm-to-market routes, including FM 1681 E and FM 3335, which connect the scattered homesteads and small centers like Nockenut.
