Carroll College Mounds
(College Hill Group)

  Out of a dozen or so mounds that used to exist here, two are preserved on the grounds of Carroll College in Waukesha - 
the oldest college in Wisconsin. The mounds are in good shape, but occasionally mowed. Tread lightly if you want to see
the mounds - Carroll College is a private institution.
