GLS-SEPM Field Conference 2009—Shawnee Hills, Illinois, late September or early October

Ancient Landscapes of the Shawnee Hills, Southern Illinois. 
Pius Weibel, Leon Follmer (ISGS) and Don Johnson (Dept. Geography, U Illinois). The trip will be a roughly west to east traverse of the Shawnee Hills to examine evidence for relict and ancient landscapes.  We will be looking at microcrystalline chert and other deposits as we try to decipher a lengthy time period of mostly non-deposition.  Hopefully, the participants will be able to assess features and evidence that appear best explained by a long, subaerially uninterrupted period of mechanical and chemical weathering, that we believe started in the Cretaceous and continues to the present.
