Dave Rearick

Rearick and Royal Robbins climbed the Vampire at Tahquitz Rock in California in 1959; though some aid was used (not eliminated until 1973), the route required 5.10 climbing, exceptionally difficult for the times.

A year later the team of Robbins and Rearick established Yosemite's first 5.10 climb: the East Chimney of Rixon's Pinnacle.

In August 1960, Kamps and Rearick made the first ascent of the Diamond, the massive headwall on the east face of 14,255-foot (4,345 m) Longs Peak, in Colorado.

Rearick received a PhD in mathematics from Caltech, defending his thesis during the spring of 1960.
