Mount Sidley (4,285m), fifth ascent and correction. The highest peak in the range got its fifth ascent, by veteran guide Mike Roberts and party. It seems that in addition to previous reported ascents in 1990 (Bill Atkinson) and 2011 (ALE guided team, see AAJ 2011), there were two ascents in the early 1990s, by Bill McIntosh and partners.
