there is a prehistoric mound on CR 271 (papermill road)
but there is a burial site on 36 west in front of RV high school where a bed & breakfast was (is) at the entrance to the administrative offices of RV.they have 3 tomb stones of an indian chief in the middle and family at both sides.
Many have driven by it daily and never realized it was there. Back when,before the house was built there, old photo's show the tomb stones in a "pig lot".
