Hygiene sits at the center of an intricate agricultural landscape in Boulder County, defined by a complex network of 19th-century water engineering projects including the Supply Ditch, Palmerton Ditch, and Oligarchy Ditch. This 2022 survey captures the transition from the high-desert plains near Rabbit Mtn and Dowe Flats to the expanding residential outskirts of Longmont. The area’s spiritual and communal history is anchored by the Ryssby Church Cem and the twin Hygiene North Cem and Hygiene South Cem, marking early Swedish and local pioneer settlements.
