Once containing 27 mounds (19 conicals & ovals, 6 linears and 2 effigies), this group is down to 20 to 23 mounds (accounts differ).
The turtle effigy is the most famous, and has inspired Beloit College to adopt a turtle as its emblem. Not incidentally, before the
settlements were built, the mounds overlooked the confluence of the Turtle Creek and the Rock River (now obstructed). The group is
in decent shape, the only problem typical for such a setting being wholesale mowing. Also, the original plaque has disappeared.
