From Pilot Knob, just above the international line, the crest of the delta extends in a southwesterly direction toward the area marked Volcano Lake; from the crest, it is downhill either northwestward toward the Salton Sink or southward toward the Gulf. Laguna Salada was occasionally filled when the flood waters of the Colorado, confronted by the tremendous Gulf tides, were forced up into this basin pocket. Along the river in the upper right hand corner of the map is the Palo Verde Valley, here labeled as the Blythe Estate.
