Now I am working on writing it up

This makes me aware of all the shortcomings of the 1st pattern I wrote, Monongahela.  Did you know I forgot to write the GAUGE in there?  It was such an ambitious thing.  Anyway, I still am confused about what I should put where and how extensive my instructions should be.

Just for fun I'll upload my Anatomy of Youghiogheny.

I hope that a picture does mean a thousand words because I get tongue tied trying to explain myself.  Despite my worst efforts I do believe that this is an easier pattern, once you get past the flat part, than Monongahela.  "Water which flows in a contradictory direction" indeed.
