How did this happen :-k
This old tree is pointing strait southeast to the St. Francis River below the mouth of the Little River in Poinsett County, Arkansas, the St. Francis is navigable by barge. It joins the Mississippi, I am not sure how old this tree is ,but it could be a marker made years ago to mark a direction to the river.
And with out erection he is still doing his job.:toothy7:
