The location of STARHENGE is determined by the shape of the land, proximity of trees, and visibility of the horizon. The existing trail will be re-routed as a part of the construction process, with the potential to increase the trail length slightly to the standard 5km. Separate trails will provide foot and wheelchair access to STARHENGE.

The designers, Steve and Chris, initially planned to seek native stone materials for STARHENGE. However, after much investigation including visiting many stone quarries in Arizona, they found that the needed combination of very large unfractured stone, the equipment to handle it, and the persons with the skill to cut and form it do not appear to exist in Arizona. Because of this, it is likely that the project will have to go out of state to find the needed materials. The largest stones will probably be made of quarried granite, with a color chosen to fit with the native rock and landscape of McMillan Mesa. It is possible columnar basalt will be used for many of the smaller stones (the Star Stones and Heel Stones). Though basalt is common in northern Arizona, unfractured stones with sufficient size will probably also have to come from out-of-state quarries.

Though the entire Double Spiral Earthwork, 300' in diameter, will initially disturb about 1.6 acres of land, the vast majority (1.5 acres) will be revegetated with the assistance of skilled restoration ecologists. Only the central 72' diameter stone circle (just over 0.1 acre) and two access paths (less than 0.1 acre) will have a crushed stone surface to handle the heavy traffic and assure wheelchair access. For comparison, the running trail already in place in Buffalo Park has removed over two acres of natural vegetation.

The designers believe that STARHENGE fits naturally with the beauty, serenity and open spaces of Buffalo Park. Further, STARHENGE will enhance our community by offering opportunities to enjoy the vast open spaces of the night sky, and help protect the park by fostering a community commitment to protect the open space and dark skies upon which STARHENGE depends.

Standing within or near the stone circle, the stones will indeed be impressive and imposing. A 6 foot person will be dwarfed by the 23-foot 50 ton portal Stone and the 16-foot Trilithons.

Though STARHENGE will certainly be visible from many parts of the park, it will not obscure the beautiful views when observed from more than a few hundred feet away. For comparison, the Ponderosa pine trees in the park are typically taller than the largest stones of STARHENGE.
