The high desert landscape of the San Luis Valley is defined by a complex network of man-made waterways including the Loveland Lateral and Empire Lateral, which support the agricultural life around Alamosa. This survey captures the western edge of the city, dominated by the Adams State University campus and the Alamosa County Courthouse. The convergence of the Rio Grande to the north and the Alamosa River to the south brackets a region where modern infrastructure, like the San Luis Valley Regional Airport/Bergman Field, exists alongside older landmarks such as the Alamosa Spanish Cem 1913. Smaller settlements like Henry, Hartner, and La Fruto dot the southern reaches of the quadrangle, connected by a grid of county roads that navigate the drainage ditches and laterals essential to this arid environment.
