Strange Glyph site and location Indeed!

A friend sent me these pictures of some very strange glyphs, I cannot answer any questions regarding location, but I can say they were found near the top of a silent volcano, in a crevice, a crevice which almost looks like it was an entrance at one time and if so, it is badly caved.... I know it is difficult to form opinions without a general location, but that is not possible at this time.... regardless any thoughts? If nothing more, Enjoy!

Perhaps some day we can tell more... Thank you to my friend, you know who you are and hope to see you very soon....
