Sign above a restroom: "DANGER. Natural toxic gas. Hazardous area. Keep out." I found this too funny to pass up. However, the reasons for the sign are not so funny.

Natural CO2 outgassing from a magma body beneath Mammoth Mountain asphyxiated more than 100 acres of trees near Horseshoe Lake in the early 1990s. The gasses become concentrated to deadly levels in enclosed structures such as cabins and restrooms (and tents -- camping was prohibited here).
