A huge cave whose entrance is located under a cemetery in the United States

In the last post we saw a necropolis located under a house, and now we will see the opposite case: an exploration under a cemetery.

A few weeks ago, CaveChronicles published an interesting video showing the cemetery seen in the image at the top of this article. It appears to be a private cemetery, given the small number of tombstones. As with the Aventuras Entresierras video we saw yesterday, the author of this video hasn't revealed its location, but from what I know, it was filmed in the United States.

Under the cemetery, there's a narrow entrance to a cave. This entrance might give the impression that it's a small cave, but in reality, the video's protagonists find themselves in a huge cavern with wide passageways and some truly spectacular parts:

You can see some screenshots from this video here. The first image shows the cave entrance. The second shows some inscriptions inside the cave, made in the 19th century. There are also more recent graffiti. Truth be told, the cave seems to be very busy.
