Hygiene sits at the center of an intricate hydraulic landscape where the waters of St Vrain Creek are diverted through a dense network of canals and reservoirs. This late 1960s survey captures the agricultural and industrial transition of the Boulder Valley, showing the growth of Longmont as it pushes westward toward McIntosh Lake. The reliance on irrigation is evident in the many named channels like the Oligarchy Ditch and Rough and Ready Ditch, which feed scattered water bodies such as Clover Basin Reservoir and Burch Lake. To the west, the landscape rises into prominent local landmarks including Rabbit Mountain and Table Top Mountain. The southwestern corner is defined by the technical infrastructure of the Antenna Field Sites and its associated Radio Telescopes, illustrating the area's role in scientific research and telecommunications.
