TB-1

TB-1 was the first seven-foot caisson installed by ROC Equipment and Soletanche Bachy Canada in Season 12, placed over the suspected Chappell Vault. The casing sank with little resistance near 95 feet, and at 160 feet a cave-in opened a 30-foot drop around it. Work stopped at 179 feet as the collapse spread under the crane.

No public source gives this hole's position.
