If anyone needs a road map of Johnson Co. Arkansas
Looks to me (and Google Earth) that the trail to the hollar is shown on the map.
I think it's the third dirt road to the left off of 123 north of Hagarville.
Anyway, here's the official Arkansas Johnson County map.

I've found it on Google satellite view before
