2017 ASA Regionals, Redfield, SD - Day 3

The team had another good day describing pits in the Redfield area. We began our day with two contrasting soils formed in silty Glacial Lake Dakota sediments above a stream terrace of the James River. First, the students described a Calciustoll on a backslope:

The afternoon was spent describing two soils formed in glacial till in the Redfield Hills (a minor recessional moraine of the James Lobe).

Tomorrow brings our last 4 practice pits southeast of Redfield, followed by a tour of a local ethanol plant. The weather for Thursday (contest day) looks beautiful!
