Bradford Graves devoted his life to working with one of the most primitive artistic mediums—stone. From now until the end of October in Kerhonkson, over 200 of his works, a permanent collection, are showcased in the park. Visitors can enjoy these thought-provoking creations for free, by appointment. Series like "The Mirror Can Crack a Stone," a collection inspired by Thoreau, epitomize Graves's style and occur throughout the park's natural five-acre landscape. Joining the old with the new, the sculptures are reminiscent of ancient artifacts while taking on organic modern forms, making these works both reflective of the prehistoric world and Graves's understanding of contemporary alchemy, physics, and philosophy.
