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.

This list shows peaks that have the most climbers that have recorded ascents. Repeat ascents are not counted, so if a single climber ascends a peak 100 times, only one ascent is recorded for the purposes of this list.

Despite the worldwide coverage of the database, the site has its greatest usage in the United States, so peaks in that country dominate this list. There is a companion list for peaks outside the USA only, ranked by the same criteria.
