Stone has been called the bones of the earth, and from it we shape the skeleton of the landscape. Rough, lichen-covered boulders hold up a hillside thick with blueberry bushes, cut granite blocks form a wall. Stone provides more than structure, it gives color and texture, a warm spot to doze in the sun, a cool path underfoot. Isamu Noguchi wrote that stone could be:
"a seat which is also a sculpture or a sculpture which may be sat on. The experience of sculpture is not only by sight. The tactile quality of sculpture is surely as important as the visual to cause thought."
