Ada, April 2 1922 Sunday.
Started out in a threatening day to see
the Drapanuella - Canyon sequence.
About one mile South of Francks
stopped to see the Franck's conglomerate and
was surprised to see in it hundreds of
joints and silicified Camarocrinus
fossils. The Hunton is my about two-quarter
mile away, and in middle Pennsylvania

not far away from the source of the Hunton.
Today the Francks and Hunton are in fault

feet.
Then drove to Canyon Creek in Section

Here the Drapanuella is dominantly a
sandstone - shale series with several zones
