The group at Fern Valley – a bit of a rain during the trip.
Fern Valley is near the southern margin of the Laurentide Ice Sheet.
Peter was able to probe meters down below the glacial moraine materials and into a thick lake clay.
Cantilevers at the toe of the Fern Valley Slump Complex.
Another case of piping within the gravels at the base of a legacy sediment fining upward sequence.
Geomorphology (Geology 300) has been taking advantage of the good weather this Fall traveling in the area. Above the full class stands on a point bar of the Apple Creek. Waves go out to Brian Merritt who experienced an injury earlier in the semester, we wish his a speedy recovery and sure could use his expertise in hydrology, carrying heavy equipment and doing much of the work (see below).
Brian augers a hole in the Kame at Browns Lake, in the background is a 350 year old white oak and we hypothesize that this area may contain old soils that have never seen the plow.
Surveying in the discharge transects and well locations.
The gaging team sets up another transect.
Taking notes – greatly appreciated when we return to the lab and try to make sense of what we measured.
The shallow wells were measured for relative water levels and water temperature.
A surprise the team discovered – Roy takes a sample from the upper unit as Julia takes careful notes. The hypothesis is that this layer, which lies uncomformably on top of fluvial gravels, is in the class of legacy sediments, eroded soils and windblown dust empounded at the site when a mill was operating in the valley.
Possible Mill or dam site?
Much of the class at Zollingers Pit in Rittman – Krysden and Andrew are not present as they were excavating sediment for their project.
The group at Browns Lake.
Discussing why we install a shallow and deep well side by side.
Returning to the vans after work in Wooster Memorial Park (aka Spangler).
