This sculpted stone is in a motif seen in many instances on this blog and in several from Arkfeld Site. This is a human head likeness in profile facing right with an expanded eye area. There have been stone removals to affect a curved nose and a tongue-like feature near the 'mouth.'
The human is simultaneously a mammoth profile figure facing right where the human and mammoth more or less share the same 'eye' feature in the stone. The human's 'nose' is also the 'trunk' of the mammoth figure. The mammoth's 'head bump' is the crest of the human's forehead in the depiction.
Also of probable significance, there is a small incised crosshatch pattern in the stone above the 'eye' hole which seems inspired by a wholly natural crosshatch feature of the stone formation itself.
