Please generate a brief description of a spooky cave wilderness scene with dank moss, a tunnel, rock, and stone.

The tunnel makes a sharp bend, skirting the edges of a huge limestone boulder which looms over the passage to the west. The stone's face is slick with sickly growths of dank moss. To the north, the tunnel narrows quickly and dead-ends in solid rock. A narrow crack in the stone looks passable.
