The best known cluster of mounds in the park is probably Sentinel Ridge Mound Group, comprised of 28 effigy, linear and conical
mounds. Some are marked, some aren't. This group is also known as Signal Hill Mound Group. To confuse the matter, the next group
over, called Procession of the Mounds, is also comprised of 28 mounds (effigy, linear and conical), and pretty much continues the former. While no pedestrian traffic affects the site, trees growing over the body of the mounds could be a bigger problem in a location like this
than elsewhere - the site is on top of the bluff and completely exposed to storms coming from west. It's only a matter of time before
some trees are toppled, taking the fabric of mounds with them (see above).
