Please generate a brief description of a spooky cave entrance with a ledge overlooking the valley below.

The ledge here at the mouth of the cave provides a splendid view of the valley below in all its mud-spattered, ill-smelling beauty. The cave entrance itself is at least twenty feet high, and a dank, sickly-sweet smoke wafts from it. To the southwest, a dimly lit passage leads deeper into the hillside.
