That?s a good find! Not my area, but I thought Big Sandy Variant at first glance.
There seems to be a good number of guessing on this one. Have you put an ID on it?
I?m not very good at identifying the types. I?m leaning towards a big sandy variant but not sold on it. My first thought was a monster brewerton but realized the base was wrong (I think....)
Could other pictures help?
Is it just me or does one side look corner-notched and the other side look side-notched?
