At last, a bright morning arrives and the researchers head to Lake Hill, a crater lake encircled by a snow-covered rim. Members thread together meter-long sections of pipe attached to a tube, or corer.Researchers found the 55-inch-long (140 centimeters) mammoth tusk, the largest ever found at a prehistoric site in the state, during a 2016 excavation at the Holzman site, located about 70 miles (110 kilometers) southeast of Fairbanks, Alaska.A radiocarbon dating analysis revealed that the tusk was about 14,000 years old, the researchers told Live Science in an email."The radiocarbon dates on this mammoth place it as one of the last surviving mammoths on the mainland," Kathryn Krasinski, a co-principal investigator of the excavation and an adjunct faculty member in the anthropology department at Adelphi University in Garden City, New York, told Live Science in the email.Back in the 1960s, Paul Colinvaux, a British-born ecologist, had collected a sediment core from a lakebed on St. The preserved layers in the core revealed that the site held a sediment record stretching back at least 14,000 years — and the spot, Lake Hill, was only a quarter of a mile away from the cave where Graham had made his discovery.The answers to Graham’s questions might well lie in the dark mud of that lakebed.
