About this map

Peach Valley and the Uncompahgre Valley dominate this mid-century landscape on the border of Delta and Montrose counties. The agricultural development of the region is clearly visible through an intricate network of irrigation features, including the East Canal, Selig Canal, and several reservoirs such as the Lower Peach Valley Dam and Middle Peach Valley Dam. These water systems contrast with the dry Arroyo beds that mark the lower elevations.

Transportation and infrastructure are anchored by the Denver and Rio Grande Western railroad corridor, which follows the path of the Uncompahgre River. To the northwest, the Star Nelson Airport and the VABM Airport survey marker indicate the area's role in local aviation during the 1950s. This survey provides a precise record of the land as it was managed before later twentieth-century expansions.
