2016 Nationals: Manhattan, KS - Day #4

The team had the opportunity to describe 5 practice pits today, four of which were just a short drive from our hotel at the KSU Agronomy Farm North on the outskirts of Manhattan. At this site, the contest organizers had prepared a nice set of 4 pits along a catena (a Paleustoll on a summit, two Argiustolls on a backslope/footslope, and a Haplustoll on a stream terrace):

Our day along this catena was split by a visit to another pit ~ 20 minutes away - an Ustipsamment with lamellae formed in reworked outwash (dune sand). We shared this pit with ISU - both team immediately started looking for lamellae thanks to their experience at Regionals in Grand Rapids this past fall.

We then headed back to the KSU Agronomy Farm North to complete our descriptions along the catena before linking up with the rest of the teams to go on a bus tour of the Bison enclosure at Konza prairie LTER:
