Dr. Henry Cowles conducted his initial studies of plant ecology and succession in this area. It was later designated a National Natural Landmark, in 1966, due to the incredibly rich plant diversity found in five habitats. Park staff continues to work hard to remove invasive species and restore native plant diversity.
Notes: Total trail is 4.6 miles.
