I'm from Washington state (brother-in-law lives in Arkansas) and have zero experience identifying points.  I considered Big Sandy but it seemed, Overstreet, too far south, but if they are called that in N.C. that's as good a name as any.  Big Sandy overlaps Hemphill on both ends, age wise.  Morrow Mountain I didn't consider as it isn't listed (Overstreet, again) for the Arkansas area.  Too many names for points that are the same in age and appearance but from different places!  That's why I was looking for help.  Thanks for the input.
