The Hundred Peaks are significant summits in Southern California that are south of the Sierra Nevada, west of the Mojave Desert, and over 5000 feet high. There is a great deal of fine mountainous terrain in this region, including 10,000 foot peaks of the San Bernardino, San Jacinto, and San Gabriel Mounains, plus scores of lower summits stretching from San Diego to north of Santa Barbara. When this list was first created in 1940, there were 112 peaks on it, but over the years peaks have been added so that now its title is terribly misleading.
Note that the Hundred Peaks Section committee will often "suspend" a peak from this list due to fire closures, access issues, or other reasons. These suspended peaks are still listed here as fully ranked peaks -- note that the policy for other Sierra Club lists is to keep them unranked. There are currently over 20 of these suspended peaks on the HPS list--many will likely be un-suspended in the future, but at present they are not required for list completion. These peaks have a note in the description of the individual peak pages.
If a peak is de-listed by the HPS committee, it will be removed entirely from the list here. This is a more severe action than suspension and is reserved for peaks where any future legal access is very unlikely.
