Walker Lake, a terminal saline lake fed by the Walker River in Walker River Basin, Nevada, was once part of the ancient Pleistocene Lake Lahontan. Lake Lahontan covered much of Northwestern Nevada and began to recede from its last highstand, or peak 12,500ya, leaving Walker Lake and Pyramid Lake today as the main remnants today.
