This lot is based on What Lies Beneath q.v. It's an adaptation of the lot for a Simbot's dwelling\workplace. Sorry, not for download as the game crashed and lost it. Plus it includes quite a few Luna items.
As you see, the place is a grotto, with some huge old rocks. It used to be a beauty spot - but as it has no water, being on a small hill, was never particularly popular.
More recently, urbanised residents of Acadia have used it as an unofficial junkyard, to dump household rubbish. One or two plants and mostly mushrooms are trying to grow between the rocks; there is a miner, and a few other bits and pieces that were dumped here. The shelter beneath is pretty bare, but has some workbenches and a tatty couch for a cat bed.
Poor Gloria was exhausted.
