1915 Map of San Juan Bautista

Social and religious history is anchored by the Mission San Juan Bautista, situated at the edge of the San Benito Valley. Educational and social landmarks appear in the outskirts, including the St Francis Orphan Asylum and several rural schoolhouses like Carlton School and Lagunita School. To the south, the wetlands of Elkhorn Slough and Moro Cojo Slough reveal the coastal hydrology before decades of modern development, while settlements such as Castroville and Aromas appear at their early twentieth-century scale.
