SWAN POINT. Swan Point is a cape that juts into San Antonio Bay in western Calhoun County (at 28°23' N, 96°43' W). The terrain on the cape is nearly level land surfaced by poorly drained soils with high shrink-swell potential and slow permeability. The site is occasionally inundated by wind-blown sea water, a condition that discourages settlement. It does, however, provide habitat for clams, snails, and a variety of water fowl. In 1985 a gravel surfaced road provided access, but halted short of the point. While there were no man-made dwellings on Swan Point in 1973, several had been constructed on the nearby road.
