Cashaqua-Rhinestreet Contact

Finally got into the field with Dr. Gary Lash this morning. A cooler cloudy day made collecting a real pleasure. Despite the recent downpours in Western New York the creek level was still relatively low. No wet boots!

Our interest in the lower contact of the Rhinestreet at the top of the Cashaqua revolves mainly around Gary’s work on oil shale and different magnetic logs at this location. Seems that there is an unexplained 13C excursion during a worldwide transgression. My part comes in with the concretions … like the top of the Rhinestreet these little buggers fall along the same layer of strata again.
