At waypoint 1514001, there are two smaller propped boulders.
These are next to each other. The larger one has a division in the base, like that of the corner propped boulder shown 9/11/2013.
Those small objects in the division are acorns donations left by squirrels.
At waypoint 504, about 600 feet away from the corner, there are also two propped boulders.
Nearby is this perched boulder, which I have shown before (11/28/2012 ). This seems to point to the smaller propped boulders at waypoint 1514001. If there was anything more, it was lost to development.
