Anaerobic preservation exemplified

Car retrieved from a Norwegian lake after 49 years.  The front end had been buried in the lake bottom mud.  Note the preservation of the paint and the shiny hubcap.

Lake bottoms, ocean bottoms, peat bogs etc are famous for their ability to preserve organic material because the environment is anaerobic (oxygen-depleted).

A recent example was the retrieval of a 1200-year old wooden canoe from the bottom of a lake here in Madison, Wisconsin.  Lots of photos and a video at the link depict the recovery process.
