Ahoy!

The top left edge of this 2inch x 1inch stone has been smoothed on two sides creating an angle of 135 degrees.

A modern looking human face can be seen on the left side of the stone below the 135 degree beige band, inset from the face of the beige band.

A cave and bear depiction is present on the face of the stone. What looks like script can be seen in the centre of the stone across a narrow band of lighter shaded rock.
