Dearborn moved... without waiting for the continents. By cutting it off at ground level, the observatory was moved 664 feet southeast of its original site to make room for the new Technological Institute building. Twenty-six men using jacks moved it for three months at a top speed of 20 inches per minute. It was in motion for a total of seven hours. The building weighs approximately 2,500 tons and the weight of the telescope pier is 125 tons.
