Page "Oak Island" Paragraph 10

Around 1967, Daniel C. Blankenship and David Tobias formed Triton Alliance, Ltd. and purchased most of the island.

In 1971, Triton workers excavated a 235 foot shaft supported by a steel caisson to bedrock.

According to Blankenship and Tobias, cameras lowered down the shaft into a cave below recorded the presence of some chests, human remains, wooden cribbing and tools ; however, the images were unclear, and none of these claims have been independently confirmed.

The shaft subsequently collapsed, and the excavation was again abandoned.

This shaft was later successfully re-dug to, reaching bedrock ; work was halted because of lack of funds and the collapse of the partnership.
