RF-1

Caisson named Restall Family 1 and sunk in Season 7 to test the teardrop seismic anomaly south of H8. It produced Chappell Shaft timbers, a pickax, pottery and dowelled timbers with Roman numerals near 100 feet, the Chappell Shaft shield at 160 feet, and heavy resistance at 181 feet. It reached a void at 202 feet, but backfill from H8 collapsed into it and the hole was terminated.

Positions on the map are approximate; each dot marks the top of the hole.
