I had noticed recently that there were various placemarks posted about Luray Caverns, but none agreed with any of the others. So I set about to find the true location. Included in the placemark folder is an overlay of a topo map showing that location.

The original discoverers and the site depicted on a postcard
Luray Caverns, in Cave Hill about 1.5 mile west of the town of Luray,VA, was discovered in 1878 and has been open for public viewing every day since then. It is a wet, or living cave, water still carving passages and depositing cave structures like stalactites, stalagmites, and columns.
