This "hole" is a simple "you are here" marker along the trail.
This upright rock marked a spot along the trail and also gave you a line to follow by using the upright edge as a line. Of course you had two different directions you could go but the map gave additional information that indicated I should take the uphill direction.
Another upright rock ( I have run into several of these in my searches for outlaw loot). This one is about two inches thick and acted as a "you are here" marker. This one did not give any additional information and the direction to go from this one was in the map.
This one is a very obvious pointer. At this spot you would go in the direction of the big point. Since this direction is somewhat subjective, meaning you cannot get an exact compass heading from this type of point, the distance traveled from this clue to the next was fairly short in distance, about 40 feet.
