Harvey Fite transports a boulder from a nearby streambed from which to sculpt the centerpiece of his 6.5-acre bluestone sculpture. As written by Ralph Moseley in his Hunter College master’s thesis:

“Once it had been transported to the spot, Fite tried to visualize what final effect it might have by constructing a small bamboo and cardboard scale model of it. The stone itself is fourteen feet long and weighs approximately nine tons, and considering this great weight Fite’s natural instinct was to rest it on the larger of the two ends, there being a flare of about fifteen inches along the entire length. However, this produced unpleasant results even in the scale model, for the object seemed, like the sculpture which had preceded it, cramped by the space and in turn the space seemed vague and limp. Fite then entirely reversed the model, resting it on the smaller of its ends, and it immediately came to life. The flare up and outward carried Opus 40 out into the sky, activating the space above the quarry and in front of the mountains so that it becomes a full voluminous dome and along with the mountain is part of the total sculpture. “
