  • The first three peak pairs on this page show the superlative unique pairs for three key metrics: Elevation, Prominence, and Isolation.
  • Most hikers or climbers that log their ascents on have a number of unique peak pairs--a set of two successfully climbed peaks such that no other registed site user has also climbed both.
  • Since virtually no one can claim to have made the only ascent ever of a peak, these peak pairs are a way to calim some uniqueness--being able to say "I am the only one to ever climb both Peak A and Peak B".
  • Many of a hiker's unique peak pairs will be relatively low, minor, or otherwise insingnificant peaks, and therefore climbing both may not be a particularly impressive achievement.
  • So the pairs above represent the most significant of all a climber's unique pairs--the most impressive unique pairs to use as a badge of honor.
  • Mathematically, the pairs listed above maximize the value of the secondary peak in the pair--for example, showing the pair that has the highest elevation for the pair's second-highest peak. Put another way, it shows the two highest-value peaks that only this climber has climbed.
  • The final listing shows the peaks (if any) where the hiker/climber is the only ascender with logged ascents.
  • Of course, all these listings are purely based on the logged climbs in the database, so they should not be taken as completely accurate.
