unfathomed
Depths not sounded
Unfathomed means not fully explored or understood—depths that haven't been measured, mysteries that haven't been plumbed.
The word derives from fathom, a unit of water depth.
The unfathomed reaches of the ocean floor remain unknown.
Figuratively, unfathomed applies to anything not yet grasped: unfathomed complexities of the human mind.
