|Eklutna_Lake||61.36||-149.02||Unknown, Unknown||0000-00-00||454 14C; 14141; Age is approximate. Bayesian model presented that integrates classic methods of estimating the chronological uncertainty of varves to produce most likely age models. Average of four ages.||Eklutna Lake is located 45 km northeast of Anchorage, at 264 m asl in the Chugach State Park. Long sediment cores (~15 m long) were obtained in 2014 at six locations across Eklutna Lake using a Uwitec piston coring system. Tephra data are presented for units correlated between multiple cores and thus, a generic location in Eklutna Lake was selected.||Tephra beds were located visually and by their high magnetic susceptibility values.||Fortin_tephra_5||Tephra Fall||Cumulate||Glass||75.67||0.26||13.44||1.37||0.07||0.28||1.54||4.1||3.13||14141||EMP||1.37||Cl=0.14; H2O=2.4||EMP|
