Tales from the Beowulf Saloon
This small mine was operated by Jacob and Robert Robineau, brothers from Louisiana. Located in a box canyon about 3 miles northwest of Deadwood proper, it consisted of two galleries, stretching to the southwest and the northeast of the entrance. The south gallery featured a significant ghost rock seam, but the brothers also managed to break through into a cavern inhabited by tunnel critters.
As of the events of “Welcome to Deadwood”, Jacob is dead and the south gallery has been collapsed to seal in the critters.
