The Relationship Between Geology and Landslide Hazards of Atchison, Kansas, and Vicinity--Fig. 6

Fig. 6. Exposure of the Atchison Formation along White Clay Creek west of Atchison (SE NW sec. 10, T. 6 S., R. 20 E.). The older till and Atchison formation were deformed by the later glacial event that deposited the glacial drift. At this location, the drift is a younger till. For more information on this outcrop, see Aber (1991).
