"Elementary Peak" (Pk 5960+, 440P) to the immediate ESE of East Watson on November 20, 2005. It is guessed that only two people have stood atop this peak: John Roper and Grant Myers on October 16, 2002. The Diobsud Buttes are beyond.
Addendum: I climbed Elementary Peak solo in August 2006 on the way back from Bacon Peak. Fay Pullen also soloed it sometime after my ascent (2007, I think).
