Rock

 

This protuberance looks like an open eye on the surface of the rock; there is another protuberance on the other side, but it is not open. There seem to be two or more minerals, but I cannot identify them. Back to Geology 101!

 

Thanks, as always, for stopping by and for all of your kind comments -- I appreciate them all.
