The Diamond is the sheer and prominent east face of Longs Peak and named for the shape of the cliff.
[1] 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.
