At the coordinates given, one will find a large, flat boulder about 9 or 10 meters south of the highway. It's very difficult to miss. Near the centre of the top is where 83C109 has been monumented. Nearby is an old, now unused, billboard. Given its present condition, there's definitely no guarantee that it will remain in place for any length of time.
Though it's not terribly wide, one may park on the shoulder by the boulder.
