Is there a way to search old NSS numbers/connect them back to the members? There hasn't been much organized caving in my county in perhaps 20 years or more. Going into a local cave yesterday that was mapped back in late 1950s I found a carbide/sooted date with a very low four-digit number that I assume is an NSS number: 1150. Is there a source or way to connect it back to owner? It's be neat to know if it was one of two people I suspect may have been involved in early Wythe County mapping.
TIA
