ZORRO CREEK. Zorro (Zoro, Soro) Creek rises just north of U. S. Highway 90 in southeastern Val Verde County (at 29°22' N, 100°48' W) and runs southwest eleven miles to its mouth on the Rio Grande, five miles southeast of Eagle Pass Hill (at 29°16' N, 100°51' W). Its short course crosses steep to gentle slopes and flat to rolling prairie over wash deposits and expansive clay mud. Generally dark, calcareous stony clays and clay loams support oaks, junipers, grasses, and mesquites. Zorro is Spanish for "fox."
