1955 Map of Olathe NW

About this map

Agricultural development along the Uncompahgre River defines this mid-century landscape on the border of Delta and Montrose Counties. A complex network of irrigation infrastructure, including the Selig Canal, East Canal, and numerous instances of the Ditch label, illustrates the intensive water management required to farm the arid terrain surrounding East Mesa. The map records several water control structures such as the Lower Peach Valley Dam and Peach Valley Dam No 1 within the prominent Peach Valley. Transportation and utility corridors are represented by the Denver and Rio Grande Western railroad line and the Star Nelson Airport in the northwest. This survey provides a precise look at the rural canyon-and-mesa geography before more modern expansion, highlighting features like the Loutsenhizer Arroyo and the high ground of Black Ridge.
