The Animas River valley serves as the primary artery for settlement and industry in this northern San Juan County landscape, supporting the communities of Riverside, Cedar Hill, and Inca. This 2017 survey details a complex network of agricultural irrigation, where the Graves Atterberry Ditch, Stacy Ditch, and Sargent Ditch divert water to the valley floor. High above the river, the geography is defined by prominent landforms such as Bushelberger Mesa and the distinctive Lone Tree Mtn. The map reveals the intersection of natural landmarks and human history, from the geological features of Cox Canyon Arch and Arch Rock Canyon to the local heritage preserved at the Cedar Hill Cem. This record of the modern era illustrates how contemporary road systems like RD 2900 and CO RD 2350 follow the traditional contours of the canyons and riverbanks.
