Stone pillars of a Native American ceremonial ground stand around a deserted fire pit, human-like profiles on a larger-than-life compass. A tiny man, no taller than a human hand, meditates silent and alone on a knee-high mountain. Dresses fabricated from aluminum hang uninhabited in the swaying trees. They are waiting for something. Perhaps discovery.

This scene may seem otherworldly, but it is very much a part of our world, part of the world that is created when we blend the surrealism of art with the serene intrigue of nature. And this seemingly untouchable world will be open to the public very soon, during the third annual Sculpture Walk at Old Frog Pond Farm (38 Eldridge Road in Harvard). It will be revealed on Sunday, Sept. 12, from 2 to 5 p.m., the opening ceremonies featuring meet-and-greets with many of the sculptors and the earthy sounds of the bluegrass band Still River. The free exhibition showcases the merging of the work of 20 artists with the rich environment of the farm, pond, and surrounding orchard.

Linda Hoffman birthed this collaboration of art and environment and is also one of the featured sculptors. Her “Rare Sawtooth Crane” can be found peering out over the lily pad-blanketed pond, its wooden body gentle in demeanor despite the sharp teeth of a saw that fashion its pointy belly. Hoffman runs the Old Frog Pond Farm orchard, where rows of organic apples and raspberries wait to be picked from 10 a.m. to 5 p.m. Wednesdays through Sundays in the orchard and berry patch—another activity to participate in during the Sculpture Walk.

The sculpture path will meander down by the pond, across a short, picturesque bridge, and along the water, looping back up through the woods. Sculptures sit in clearings along the trail, almost a humanized extension of the natural surroundings. A piece by Patrick Pierce combines wood and copper, the two materials branching effortlessly off one another as if they are giving their own modern take on the tree.

The River Stone garden next to the pond speaks poetry, fruit and clouds etched into smooth stones, the meaning hidden from those who do not try to decipher it. Some works of art are close to the earth, such as Amy Nolen’s ceramic bodies sleeping in the garden, while others stand sentry by the water, like the regal prayer flags that, as Hoffman notes, allow wind to send their prayers to the world.

And in the largest clearing of all sits that mysterious Native American congregation ground, Blase Provitola’s medicine wheel, an enormous stone compass designed to determine not only one’s physical path but one’s spiritual path as well.

The world of the Sculpture Walk will be available to the public Saturdays and Sundays from 1 to 5 p.m. through Columbus Day, spanning the early fall months when the natural world is, like us, shifting and changing but very much alive.
