For 20 years Outdoor Sculpture at Maudslay has provided a dynamic three-week non-juried exhibition featuring local artists and community members interested in sharing their unique understanding of the world through site-specific sculptures in Maudslay State Park. The annual show which has produced over 700 works of art is open to all artists with a connection to the North Shore and Merrimack Valley region and is organized by the artists themselves who volunteer their time and materials.

Participants include a Montserrat professor, a computer science teacher, a Pingree math teacher, a game designer, a graphic artist, a store owner, a maker space founder, a general contractor, an author/illustrator, three home school students, a bass player, a town selectman, three web designers, a librarian, two engineers, an architect, a poet laureate and Bonnie Jean Malcolm, a professional artist in her mid-90s.
