Grades 8-12. This project describes to students the great hurdle in the Hale Telescope’s construction: successfully transporting the 40-ton, 200-inch mirror and its packing materials from upstate New York to the top of Palomar Mountain in southern California. Documents include shipping manifests, conversations regarding the movement of the mirror, and photographic documentation of the mirror’s journey up Palomar Mountain. These sources can be used for inquiry-based learning exercises.
