A picture I found. Some of the older stores in Fredericksburg still have postcards with it's picture similar to this one. It was around 7 to 8 feet high. We used to jump from the ledge next to it to get on it.
If I'm not mistaken, the rock is now about where the photographer taking this picture was.
