List Description

This list, like all the other "Usage" lists, will change over time as ascents are entered into the database. This list is automatically recalculated once a day, so a completion of all these peaks is a moving target that may be frustrating for a climber.

The "Ascents" column above show the total number of unsuccessful attempts on a peak logged in the database. Multiple failed attempts by one climber are all counted. However, note that many registered site users do not log their unsuccessful ascents, so this list is not very robust statistically. However, it does give a somewhat interesting picture of some worldwide summit that are perhaps among the most difficult to ascend.

A personal note--I have long maintained that there should be no shame or stigma in an unsuccessful attempt. They are excellent learning experiences and a sign of wise maturity in the mountains. Never climb with someone who has never turned back! And don't be afraid to log your trips where the summit was just not in the cards.
