Pedon Note:
Weather: overcast, hot and humid becoming sunny. Sampled by NSSL.
Largest clast size is 11 inches along long axis. Pedon has an old plow
layer; undisturbed birchwood soils. Generally have a thin A to E to Bs
surface with Bw horizons in the subsoil. Silt coats on top of gravel and
cobbles; bottoms are clean. Silt coats also on ped surfaces which were in
contact with coarse fragments. Clods oriented properly, taken for thin
sections. Till is more related to the Montauk type till rather than the
Paxton type till.
