From Bob: "So for Blossom,  referencing the pic, top layer is onondaga LS for the man made wall (upper right). Below that is the Centerfield. That would be at least the 3 layers seen in the pic. Possible it may also include the slope layer that touches the creek bed. That would then be the Levanna shale."
