Photo showing tilted tress in the "drunken forest".  The trees grow atop the Slumgullion earthflow, which is four miles long and 2000 feet wide, near Lake City, CO.  As the ground slowly moves, the trees continue to readjust toward the sun, making the trees appear almost twisted.  The original earthflow began about 700 years ago, damming a creak and creaking Lake San Critobal.  Another flow began about 300 years ago, and moves as much as 20 feet per year (see the USGS Web site for more information).
