Mystery Mark

We found this mark on a horizontal rock near Ramah, New Mexico.  It’s about 4 or 4 1/2″ across.  The hole in the center isn’t very deep, probably less than an inch.  Our best guess was the mark left after using a bow-drill to start a fire – used many times.   Do you know what it is?

  1. I’m not sure a bow drill would leave the concentric rings around the center hole. They are definitely rubbed rings though – very curious.
