In that spirit I present to you some geomorphs for your next adventuring session.
The Organ-Hendricks Cave System is one of the largest in the state of West Virginia. Giant ground sloths, sabre-tooth cats, grizzly bears and all other sorts of bones have been found in the cave to add flair and adventure to the trip.
Here are two different geomorphs of the caves, sourced from the Flickr account of G.S. Springer.
