1927 Map of Riverdale

A robust grid of named roads, such as Elkhorn Avenue and Mt Whitney Avenue, connects the surrounding agricultural land. The map captures a transition in water management, showing the South Br Island Canal and Cando Ditch alongside natural features like Sand Slough and Crooked Slough. Local community life is anchored by rural schools, including Liberty School, Laguna School, and North Fork School, providing valuable markers for genealogical research into early twentieth-century valley families.
