El Centro and Imperial anchor this detailed study of the Imperial Valley's complex irrigation and agricultural landscape. The map reveals a dense grid of water management features, including the Central Main Canal, Dogwood Canal, and numerous laterals and drains like Dahlia Lateral Eight and Rice Drain Two, which are essential to the region's productivity. Beyond the urban centers, smaller settlements such as Wilsie and Anza appear alongside industrial and transportation landmarks like Jewett Siding and the Imperial County Airport. For local historians, the placement of the Imperial Cem and Evergreen Cem provides valuable genealogical reference points. Unique social landmarks of the early 21st century, such as the Motor Vu Twin Drive-In, stand in contrast to the extensive network of rural roads and canals that define the valley floor.
