Old Miner Dredge Ghost Picture

"(This picture was) taken while my husband and I were in Alaska on our trip. ...we were viewing an old miner dredge and my husband took this picture with his camera. We didn't have the film developed until we got back to Florida. At first we thought it to be damaged, but on further examination I could see the ghost under the ectoplasm. He is standing on the dredge arm looking down to what could be the ghost of a dog or mule. I understand during the gold rush days the pack mule became a true pet of the miner."
