PLEASE DON'T, break your rock, your drill hole has a lot of information on it, photo the entire rock sometimes theres a feature in the shape of it, it seems to be on an angle, if it is then its a mooring hole and should be in the shape of transmission funnel, big at the top and small at the bottom or have a concave bottom. If it looks to the side then it has been my experience that a drill hole that big will send you away to look somewhere else, just stay with the trail, just look at the shape of the rock to see if it matches the surrounding terrain, there will be other things in the area to indicate the direction, if not then stay on the trail that got you there. Should be something else within a couple hundred feet.
