In 1954, the first proposal made to the
National Park Service to climb the Diamond was met with an official closure, a stance not changed until 1960. The Diamond was first ascended by
Dave Rearick and
Bob Kamps, August 1–3, 1960, by a route that would come to be known simply as
D1. This route would later be listed in Allen Steck and Steve Roper's influential book
Fifty Classic Climbs of North America. The easiest route on the face, the
Casual Route (5.10-), was first climbed in 1977 and became the most popular route up the wall. ==See also==
