unplumbed
Depths not sounded
Unplumbed means not measured or explored to its depths.
The word comes from the plumb line used to measure water depth.
Unplumbed depths or mysteries remain unknown or unexplored: the unplumbed recesses of the human mind.
Less commonly, unplumbed describes a building lacking plumbing fixtures.
