Strat Column from Illustrator

Here is the stratigraphic column of the Westphalia outcrop that me & Dr. Parcell measured in Missouri. It contains the Roubidoux, Gasconade, and Jefferson City/Cotter Dolomite formation of the Arbuckle Group in the Early Ordovician Period.

It contains mostly fine to coarse crystalline cherty dolomite with some sandstone beds. There are some stromatolites and thrombolites(???) in a few of these beds.

I have not made the legend as yet, but I will be put it up later. There is 50+m of thickness so it looks a little blurry.


  1. Wow! That looks impressive. Did it take long to do?

  2. Well mostly cause i forgot to save my work before it crashed :( So i had to redo it all over again!
