Average calculated from analyses of seven individual samples from seven different locations (see individual samples for description): 96TDS3A, 96JF9A, 96TDS15Q, 97EC18N, 96TDS30A, 96TDS33A, 97EC15E (see Figure 14a in Carson 1998). Scattered 1-2 cm pumice lapilli, gray to light brown, dispersed in a 10-15 cm thick sediment horizon. Tephra collected from beneath the Funk/Fisher ash or directly above the late Wisconsin diamicton. Composed of easily recognizable 1-2 cm lapilli fragments evenly dispersed within a layer of non-volcanic (typically eolian) interstitial sediment. |
