OBAR HILL. Obar Hill, at an elevation of 590 feet above sea level, rises some 100 feet above adjacent valleys and about thirty feet above State Highway 95, which crosses its shoulder just east of its crest at a point (29°40' N, 97°07' W) one mile south of Flatonia in southwestern Fayette County. Its name may be derived from the family name of John and Alexander O'Bar, who settled in Fayette County before 1836. Soils in the area are characterized by shallow sandy loam overlying layered sandstone. Vegetation consists of hardwood and pine forests with native and introduced grasses. Early accounts of Flatonia indicate that much of the sandstone used in building the town may have come from the eastern slopes of Obar Hill, and an abandoned quarry in the area supports this contention.
