Question: who dug the tunnels on oak island?
Answer: William Chappell and Gilbert Hedden (1928–1939) William Chappell became interested and excavated the pit in 1931 by sinking a 12-by-14-foot (3.7 m × 4.3 m) 163-foot (50 m) shaft southwest of what he believed was the site of the 1897 shaft (which was thought, without evidence, to be near the original pit).
