A gold and silver mine discovered in 1840. A newspaper article from the era mentions that the shaft was right at the shoreline which meant that no mining could be done during high tide and pumping required before digging could begin. A badly deteriorating cabin was on the location also as a bonus. A 1935 State mineral survey only mentions a 90′ shaft. The article says that the shaft was 9′ wide. A female gate guard at the fort said that her father forbade her from going near in case she fell in.
