1953 Map of Allendale

Education and community landmarks are clearly marked, including the Browns Valley School and the Union Chapel, alongside evidence of older rural infrastructure like the Grant School (Aban'd). The terrain transitions sharply from the flatlands of the Mt Diablo Meridian into the rising elevations of the English Hills, where drainage systems like Putah Creek and Sweany Creek define the watershed. Notable industrial and utility markers include the Vaca Dixon Substation and an Airport Abandoned, providing specific points of interest for local history researchers and genealogists tracing early land use.
