The Conejos River and Rio San Antonio converge in this high-altitude San Luis Valley landscape, defining a complex network of agricultural irrigation. Elaborate water engineering is evident through the presence of the Lasauses Ditch, Rincon Ditch, and Eightmile-Ditch, which divert water to sustain the arid valley floor. The geography is dominated by the volcanic rises of the San Luis Hills, featuring landmarks such as Flat Top, the Fairy Hills, and Piñon Hills. Toward the northeastern corner, the Lasauses Cem serves as a primary genealogical landmark near the river's edge. The terrain varies from the level expanse of Greasewood Flat to the deep incision of John James Canyon, while Emory Orr Spring provides a critical natural water source amidst the scrubland and peaks.
