This week Gary and Jack find a possible copper-wrapped parchment scroll.
Renowned gemologist and jewelry expert Peter Schneirla congratulated the team on their latest find from last week.
Now they are tracing the gold in the water toward a previously unknown depositor tunnel in "the most interesting area they've explored in the last 10 years".
This is where the technology gets cool: they're going to re-crib the Garden Shaft with "waterproof wood" to make it safe for humans to descend! What

After centuries of previous searcher attempts to crib a tunnel, this will hold up to the water pressure? And what's the point of sending humans down if all they're looking at is new waterproof wood walls? Supposedly they'll also be able to tunnel sideways as needed to follow the newly discovered depositor tunnel to find the gold, but I'm skeptical until I see it work.
