Gilbert level 11 – 10 ka

Following a 2.5 thousand year period of decline, between 11 and 10 thousand years ago, the lake rose once more to 1295m (4250 ft) above sea level before continuing to decline. This event formed the Gilbert shoreline. This minor rise in lake level covered 10,622 sq km (6,600 sq mi) and marked the end of the Lake Bonneville cycle.
