Mt Surabachi from the air.

All,
Thanks for posting the pics. I also have wondered about the "tunnels" but never have heard about tours, or excavations or any interest at all, on what they may contain.
Obviously graveyards are touchy things, and that is hallowed ground there... many fell... enemy and friend.
Incredible history there....

Dug something up on an ad for Harlan Glenn and Battle rats... its a good teaser!
