AL-6 | 59.47 | -161.11998 | Kaufman, D. S. | 3434 ± 142 14C AMS; 7993; Age is approximate. Derived from age model in Kaufman and others (2012). | -1480-- | Lacustrine core from Arolik Lake in the Ahklun Mountains, southwest Alaska. The cores contain interbeds of mud and detrital organic material and at least six prominent tephra layers. The tephras appear as distinct beds of angular, very fine to medium sand-sized pumice grains, glass shards, and primary minerals. See Kaufman et al. (2003) for detailed description. | 185 cm bottom depth in core (tube depth, not tephra-free depth); 16 cm thick; bubble-walled and tricuspate shards, some blocky glass. | UA1970-P2 | Tephra Fall | Cumulate | Glass | 71.15 | 0.49 | 15.12 | 2.53 | 0.13 | 0.5 | 1.82 | 5.13 | 2.93 | Reported standard deviation of zero. 100 | 7993 | EMP | 2.53 | Cl=0.2; H2O=1.47 | EMP |
