Oak Island & Frog Island - do they both have Money Pits?

Oak Island is just one of 365 islands in Mahone Bay and is by no means unique by harbouring a mysterious pit.
Frog Island, only a short distance across the water from Oak Island holds a secret of its own. The island also has a pit of unexplained origin which has been the subject of some interesting discussions as to whether this formation is connected to the Oak Island Money Pit.

Daniel J.Sullivan was part of an excavation of the Frog Island pit. Here follow a couple of his photos from 1979.



Daniel looked into how it was possible to move large quantities of soil silently, and without a crane. He goes on to say:

"That was a painful, and dangerous excavation, but provided many artifacts, and reams of data. The pit was originally a sinkhole, and overlies the same strata common to Oak I. The excavation was terminated at 27', due to the influx of water, and dangerous conditions. That large chained boulder behind Drew was later suspended directly over us. Manmade artifacts were found to a depth of 25'.

We worked all of Frog I. in the years, 76, 77, 78, 79, 1983. Many of Peter Beamish's metal detection holes were still discernable, but we made spectacular finds in spite of their efforts, especially in the swamp. Of course our equipment was more sophisticated. Frank Ernst allowed the Beamish group to camp on the island in 1965. There is strong evidence that suggests many men were housed on Frog I. during the period of Oak I. construction."

It would be interesting to ascertain the nature of the man made object Daniel mentions to see if this is another man made structure which may very well hold clues to the creators of the Oak Island Money Pit.

Here follow some photos of the Frog Island pit today, taken on a trip in June 2008.







Is this chain the same one Daniel mentions, seen holding up a boulder in his earlier photo?
