This is a simplistic grouping of peaks based on data from peak checklist pages. Just because a peak is in a less-crowded group, you may still feel crowded due to route difficulty or terrain features. Little Bear Peak is a good example: Climbers often feel the route is crowded when there are more than just a few people climbing in the crux area. Generally, if a route is rated Class 3 or more difficult, it is best to climb on off-peak days when there will be less climbers. Currently, Longs Peak is the only Class 3-rated peak (Keyhole route) that frequently has hundreds of climbers on summer weekends. It should also be noted that there are is no "official" list kept of how many people climb each of the 14ers.
