I always notice balanced rocks. In the Southwest, they are not that uncommon. But it is seldom that we see one that this close to becoming unbalanced. I am not quite sure what is keeping this massive rock suspended and balanced on the side of base rock. It is hard to visualize the size of this rock but it is about 15 feet high and probably weighs several tons. This is probably one of the most persuasive arguments that there is very little seismic activity in this area.
