SAN GERONIMO CREEK
SAN GERONIMO CREEK. San Geronimo Creek rises six miles north of San Geronimo in northwestern Bexar County (at 29°42' N, 98°47' W) and runs southwest for twenty miles, through Bexar, Bandera, and Medina counties, to its mouth on the Medina River, nine miles northeast of Quihi (at 29°25' N, 97°54' W). The upper half of San Geronimo Creek flows through steep slopes and limestone benches surfaced by generally shallow clay loams that support open stands of Ashe juniper and live oak. Along its lower course the stream crosses rolling terrain surfaced by moderately deep to deep soils of sandy and clay loams often used as cropland.
