The Sangre de Cristo Range anchors this mid-century survey, dividing the high desert floor of the San Luis Valley from the eastern plains. To the west, the landscape is defined by the massive dunes of Great Sand Dunes National Monument and the historic Luis Maria Baca Grant No 4. This era shows a dense network of early irrigation such as the San Luis Canal and Union Lateral Canal, supporting settlements like Alamosa, San Luis, and Manassa.
