1957 Map of Alamorio NE

About this map

East Mesa provides a stark contrast between engineered agricultural development and raw desert terrain in this mid-century survey of Imperial County. To the west, a highly organized grid of irrigation and drainage infrastructure, including the Moss Lateral, Oasis Lateral, and Pansy Lateral, defines the landscape. This intricate network of laterals and drains—each named after flora or natural elements—illustrates the intensive effort to reclaim and cultivate the desert floor. In striking opposition, the eastern portion of the map is dominated by the shifting topography of the Sand Dunes. The transition between these two worlds is marked by a prominent Levee and the Jeep Trail, highlighting the literal edge of cultivation. Small-scale industrial and transport features like a Gravel Pit and a remote Landing Strip punctuate the grid, serving the logistical needs of this specialized agricultural zone.
