Calipatria and Westmorland anchor this 1990s agricultural landscape, where the intensive irrigation network of the Imperial Valley is mapped in exacting detail. The geography is defined by a dense grid of water management features, including the Vail Supply Canal, Gerrard Canal, and dozens of numbered laterals and drains that support the region's produce fields. The New River and Alamo River wind through the terrain, with the latter feeding into the wetlands of the Imperial State Wildlife Area near Finney Lake.
