Then the pair reached a side passageway that was unmarked!
They slopped forward, feet sloshing the muddy floor, no longer trying to avoid the water that oozed in rivulets down the narrow passageway, back toward the entrance, now out of sight behind them.
Dean examined the ground for tracks but the water, which while shallow, in most places covered the width of the narrow passageway and obliterated any footprints.
The passageway continued beyond where Martha had ventured and the Deans continued another hundred yards but once more the passageway forked.
A drift or entry is a horizontal passageway starting from the outcrop and following the deposit.
