While in the Missoula, MT area, I had the opportunity to look for fossils in the mid-Tertiary lake beds near Drummond, MT. Lots of fine grained shales (many readily split). Ben found a great fossil Hymenoptera. I found a very well preserved leaf along with numerous plant fragments and some midges. The sediments are along a large roadcut north of Drummond. Lots of climbing and splitting of shape to find these specimens.
