Marquez Ranch and the small settlement of Los Posos anchor this high-desert landscape in Sandoval County, defined by a complex network of arroyos and distinct mesa formations. The terrain is dominated by the broad rises of Cucho Mesa and Bernalillito Mesa, separated by drainage systems like Arroyo Cucho and Arroyo Bernalillito. Resource extraction and water management are primary features of the area's development, evidenced by the presence of the Polka Dot Uranium Group and Yellow Cliffs Group mining interests. Hydrological engineering is also prominent, with the Rio Salado Detention Dam Number 18 situated near the western edge. Reliable water sources in this arid environment are specifically marked by the namesake Ojito Spring and several livestock watering points including Ojito Tank and Peñasco Tank. Navigational access is facilitated by Indian Service Route 3 and Ridge Road 113, which cross the winding course of the Rio Salado.
