At its greatest extent, the lake covered about 930 square miles, of which roughly 500 square miles of sediment remain today. The central 230-square-mile area of the ancient lake bed preserves exceptionally rich fossil deposits, along with diverse geological features such as deltas, beaches, springs, and nearshore sediments. The lake’s unique chemistry inhibited decay and scavenging, allowing delicate remains to accumulate undisturbed. Over time, millimeter-thick layers of limestone were deposited in alternating bands, forming finely laminated rocks that now contain the highest concentrati
