that limited the telescope's usefulness. That led to engineer Tom Hoffman being appointed by Whipple to search for a site in the U.S. that would provide a clear view of the sky at a high elevation, with minimal surrounding light pollution. After searching many locations, southern Arizona with its dry air and high elevations, and the assistance of The University of Arizona, brought Hoffman to focus on Mt Hopkins. Whipple agreed, leaving the challenge of how to transport an diameter glass mirror and build a telescope on an mountain that had no road.
