How To Find/Detect Nested GRE Tunnels?

Greetings All, I am told there are nested GRE tunnels somewhere on our Cisco routers but given the deplorable state of the documentation, no one has a clue where they are. Is there a way to find out where they are? It would help a ton. Thanks!

Edit: There are dozens upon dozens of tunnels on these routers so I am looking for a quicker/ higher level way to identify them as opposed to going one by one.
