Monumental Star Map
Featured on December 17, 2021
Artist Oskar Hansen works on Monument Plaza at Hoover Dam, which he created for the 1935 dedication. The plaza floor is a giant star map, indication the positions of key stars at the moment of the dedication (left images). The layout is festooned with astronomical details, including a depiction of the Pleiades star cluster and its brightest star, Alcyone, shown at the time of the dedication (top left) and in more modern times (right).
