LS-A | 60.21 | -159.75998 | Kaufman, D. S. | 5835 ± 155 14C AMS; 7993; Age is approximate. Derived from age model in Kaufman and others (2012). | Lacustrine core from Little Swift Lake in the Ahklun Mountains, southwest Alaska. Little Swift Lake is a small (0.7 km 2 surface area), 24-m deep drift-impounded basin capturing the drainage of a deeply carved; 10-km-long glacial valley. The drainage basin has no glaciers today, but extant glaciers occupy cirques 15 km to the southeast. See Axford and Kaufman (2004) for detailed description. | 318.5 cm bottom depth in core (tube-depth, not tephra-free depth); 0.5 cm thick; fine sandy tephra; blocky pumice, generally crystal-rich, some bubble- walled and tricuspate shards. | UA1794-P2 | Tephra Fall | Cumulate | Glass | 66.78 | 0.71 | 15.43 | 5.5 | 0.21 | 0.89 | 2.83 | 5.24 | 2.26 | Reported standard deviation of zero. 100 | 7993 | EMP | 5.5 | Cl=0.16; H2O=0.74 | EMP |
