To answer your questions, sort of. Almost all the locations are not published. You cannot find them on the net like you can for others. It is a vandalism thing. And you have to know what you are looking for or you will walk right past them. So yes, more updates. In fact, there is one within sight of the top of the Rubicon trail, and no one knows it is there even with as much traffic as it has. There is a new set I found out near the Hell Hole trail that are newly discovered as of two years ago. We also may have a line on some near the Fordyce Creek trail that are unexcavated. So stay tuned
