The document is a map of the Mount Pleasant Nature Park that includes three trail loops:
1) The Clayton Thompson Trail recognizes Clayton Thompson's work rehabilitating Mount Pleasant Creek and his work in the park as County Forester.
2) The Haight Mill Heights Loop describes how Elijah Haight operated a grist and carding mill on the site in the 1840s, with the flume's rubble still visible.
3) The Racey Ridge Loop notes that "Squire" James Racey, an early owner of the property, was a prominent colonial elite who built his log castle above the ridge.
