Various formations are mentioned within this website and some readers may be unfamiliar
with one or more. The following chart is a simplified interpretation of published data and is
provided to allow these formations to be put into perspective by the reader. The depositional
environment is much more complex than this "orderly" organization, however, the jumps in time
and place, encompassed by this website, preclude proper detail.
