Elemental plane of earth module

[Crake]

Hey guys, I was wondering if anyone knows of any good dungeon module for the elemental plane of earth? Or barring that, some kind of vault/tomb? I'm not looking for a whole adventure, just a decent dungeon to fit into my current adventure. Players are levels 11-12 at the moment

The only adventure that even at least takes part on the Elemental Plane of Earth is IM1 The Immortal Storm from the old BECMI days. It came out in 1986.

At one point the immortals have to go to the Elemental Plane of Earth and deal with elementals and other hazards. I don't remember all of what happens there but it might be a good place to start for inspiration.
