The triangular alluvial fan created by past depositional cycles signifies the end point of moisture in the intermittently flowing Mojave River. Within the confines of the fan are dark, cultivated fields where dry farming, particularly center-pivot irrigation, is practiced. Other field patterns appear in close proximity to the Mojave River as it bends gradually southward. Discernible are white, dry lakebeds and two dark, irregularly shaped lava beds southeast of the fan.
