The striking bluff is a hard core that remains from a larger sheet of
Cambrian sandstone which has mostly eroded away. Around 19,000 to 15,000 years ago it was an island rising above
Glacial Lake Wisconsin. On top of the bluff grow
red oak,
black oak,
white oak,
red pine,
white pine, and
jack pine.
Buzzards also haunt the top. == References ==
