Chatfield Hollow Picnic Shelter sits upon Chatfield Hollow Brook, an ideal place to swim, fish, picnic, or hike. Reminders of early history include several old building foundations, a restored waterwheel on the upper pond, and a covered bridge reproduction spanning the brook. Chunks of oddly shaped metal fragments found near the watercourse are evidence that an iron smelting furnace worked native ores into metal for implements. Artifacts found in the vicinity of Indian Council Caves indicate that Native Americans once gathered amid the rock recesses and overhangs. An Indian trail once paralleled the brook, along what is now the park road. Early settlers made use of the stream for waterpower. Descendants of three Chatfield brothers, who arrived from England about 1639, were believed to have operated a gristmill along the brook.
