I would like to preface this with, I don't consider this violating guidelines because the place I'm talking about is relatively well known and has multiple videos of people visiting it, but I had some questions about the cave for people who had been there.
A while ago I found a website talking about caves on the Nantahala River, and I was very exited as I'm near the region and don't have many caves here. The only thing I was curious about, is that I couldn't tell if the cave was an actual cave, or just a rock shelter that happened to be called a cave. The photos don't really help and none of the videos of people going there help because they clearly don't plan on entering the cave even if there is one there. Here's the link to the website I found it on: https://www.be-roberts.com/se/nc/nant/cave/caves1.htm You can also find videos by just Googling "Indian Grave Caverns" or "Indian Cave Nantahala."
I appreciate any info you have on this. Also sorry if this violates community guidelines I really wasn't sure if it did since it was pretty well known.
Based on the geology, what you're seeing in the photos is very likely all that's there. That geology doesn't lend itself to forming "going" cave passage.
The Flittermouse Grotto of Ashville, NC is who you'd want to reach out to about caving around that area, though. There are a lot of nice and highly knowledgeable folks in their grotto who are also avid hikers and likely know this spot
