Compose a short description of a spooky cave wilderness scene with vents, mud dauber's nest, and rock pile.

The passage is blocked by an old cave-in -- tons of rock cut off movement into a smaller side passage. Steady streams of hot steam billow from several chinks around the edges of the rock pile. The vents in the wall are all very small, giving the appearance that the tunnel is covered with a huge mud dauber's nest. Jets of steam spray occasionally from the holes.
