Oak Island is just one of 365 islands in Mahone Bay. Frog Island, only a short distance across the water from Oak Island holds a secret of its own.

A mysterious pit filled with water 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 Island.

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.”

On our own visit to Frog Island, we were able to locate the pit and conduct a small investigation of our own.

In recent years Birch Island has crept onto the internet as an island possibly connected to the Oak Island mystery. What many of these blogs hang their argument on is the presence of a mysterious ‘triangle’ which some people believe to be man made in connection with the construction of the Money Pit and stone triangles on Oak Island.

Sadly, these theories hold no basis in proper investigation, as it soon became obvious as we neared Birch Island. The famed ‘triangle’ was no more than a mosquito infested swamp, completely natural in formation and totally unpenetrable. Birch Island itself is very beautiful with many wild rose buses, a sandy shoreline and a haven for wildlife. Sadly, we saw nothing remarkable which could link it to any mystery, but it is a peaceful place nonetheless.
