1931 Map of Iola

Genealogists can trace burial sites at Keefer Cem and Nash Cem, or locate the Bundy Sch tucked along the lower drainage of Long Hollow. The river corridor itself is marked by numerous named water bodies, including Carr Lake, Donahoe L, and San Antonio L, illustrating the hydrological character of the region before modern river management altered these seasonal basins. Large swaths of the southern portion remained an Unsurveyed Area at the time of this survey, highlighting the frontier character of the Texas interior during the early twentieth century.
