Bothin Marsh is a half acre (.2 hectare) wetlands in Marin County, California.[1] Parts of the wetlands are in Bothin Marsh Open Space Preserve, a regional park.[2]
The marsh, positioned at the northern arm of Richardson Bay is fed by Mill Creek. Bothin Marsh is situated not far from Triangle Marsh, although the latter is situated on the northern edge of the Tiburon Peninsula. It is likely that Native Americans gathered estuarine resources from Bothin Marsh, as they did from nearby Triangle Marsh.[3]
