Chart of G1C1 normalized and linearized excess Pb-210 data for core G1C1.

       (d) G1C1 selected metals data

Chart of G1C1 excess Pb-210 data for core G1C1.

(a) Cs-137, (b) excess Pb-210, (c) excess Pb-210 normalized to the surface Pb-210 concentration and linearized using the natural log, and (d) selected metals data for core G1C1. See the Methods section for more details. Cs-137 concentrations do not show a distinct peak and the Cs-137 onset is at 25.25 cm. The Pb-210 concentration do not exhibit a distinct peak remaining nearly constant over the top 20 cm and then declining down to background values below 27.75 cm. Cu, Pb, and Zn concentrations do not peak at any interval though they appear to increase above background concentrations above 30.25 or 32.75 cm.
