If you are talking blowing rock NC. I am 45 miles north in shady valley TN. I have a campground named switchbackcreek.
I'm talking about a geological preserve of Atlantic Ocean beach oolitic limestone rock formations along Jupiter Island, FL. Heavy surf can create geysers of ocean water through the rocks.
Was up to Blowing Rock in your region decades ago, before it was decked out like it is now. It's a beautiful overlook. You've got an attractive campground down there in NC!
