Two in one blow ..Neato
What a difference a working camera makes!
The OverS examples of the Baker dont look much like your find.....so I went to the Doctor's book.....WOW...RIGHT ON. Good matching example and it may well be your first Baker find...the defined range looks like a few miles around Barksdale ( OverS however pegs it as going into NM.)
Another point of interest. OverS does not list a Merrill at all. The Doc's book has a very good display of Merrills which include very definite "square " ears like yours ( there was a lot of sq ears found at the site that were taken as Frio )
Merrill range shown as a wider radius around BarksD than the Baker and the Frio extending from Barks more to the SE.
