Proposal Rocks is the name of a 29.9 acre nature preserve owned by Joshua's Trust in that features a group of granite boulders. It was donated to Joshua's Trust in 2003, and in 2009 was connected to 134-acre Coney Rock preserve by a 5.9 acre space of land. The site was named Proposal Rocks because the previous owner Leonora Mullane's parents had gotten married in that spot.
