Southern California Peaks Over 10,000 Feet/3048 Meters in Elevation

Mount San Antonio (10,064'/3068m) as seen from the Pacific Crest Trail

The following is a list of the peaks that are greater than 10,000'/3048m in elevation in Southern California.  Click here for a topographic map.  See also the update from 29 June 2015, below.  Each peak is indicated by a lettered marker.  You'll need to zoom in and scroll around.  The letters in the list below correspond to the markers on the topo map.  Placement of all markers is approximate.

UPDATE 16 July 2015:  Many (but not all!) areas in and around the San Gorgonio Wilderness are currently closed due to the Lake Fire.  See Lake Fire Closure Map for details.

UPDATE 29 June 2015:  I've now put up a new post, a post that lists not just the peaks over 10,000 feet in elevation in Southern California but also all peaks over 9,000 feet in elevation.  With it is a much improved map.  See:  Southern California Peaks Over 9000 Feet (2743 Meters)

UPDATE 25 Nov 2013:  Based on input from others and my own observations in the field, I have added Shirley Peak to the list.

5. (E) Anderson Peak – 10,840'+/3304m+  (no spot height available) – San Gorgonio Wilderness – USGS, HPS 
6. (F) San Jacinto Peak – 10,834’ /3302m (the topo map specifies 10,804', but 10,834' is the widely accepted elevation) – San Jacinto Wilderness – USGS, HPS

10. (J) Little Charlton Peak – 10,696’/3260m – San Gorgonio Wilderness – USGS, Not HPS 
11. (K) Jean Peak – 10,670’/3252m – San Jacinto Wilderness – USGS, HPS 
12. (L) San Bernardino Peak – 10,649’/3246m – San Gorgonio Wilderness – USGS, HPS 
13. (M) Alto Diablo Peak – 10,563’/3220m – San Gorgonio Wilderness – Not USGS, Not HPS
14. (N) East Dobbs Peak – 10,520+/3206m+ (no spot height available) – San Gorgonio Wilderness – Not USGS, Not HPS
15. (O) Folly Peak – 10,480+/3194m+ (no spot height available) – San Jacinto Wilderness – USGS, HPS 
16. (P) Dobbs Peak – 10,459’/3188m – San Gorgonio Wilderness – USGS, HPS 
17. (Q) Miller Peak – 10,400'+/3170m+ (no spot height available) – San Jacinto Wilderness – USGS, Not HPS
18. (R) Shirley Peak - 10,388'/3166m - San Jacinto Wilderness - Not USGS, Not HPS 
19. (S) Marion Mountain – 10,362’+/3158m+ – San Jacinto Wilderness – USGS, HPS.  Note:  There is a spot height (10,362') marked on Marion Mountain.  However, the marked spot is not on the highest point of Marion Mountain.  Marion Mountain is clearly higher than 10,362 and is probably higher than nearby Shirley Peak.  See Is Marion Mountain "Wrong" on the USGS Topo? for full details.   
20. (T) Grinnell Mountain – 10,284’/3135m – San Gorgonio Wilderness – USGS, HPS 
21. (U)  Lake Peak – 10,161’/3097m – San Gorgonio Wilderness – USGS, HPS 
22. (V) Newton Drury Peak – 10,160'+/3096m+ (no spot height available) – San Jacinto Wilderness – USGS, HPS 
23. (W) Ten Thousand Foot Ridge (high point) – 10,094’/3077m – San Gorgonio Wilderness – Not USGS, HPS 
24. (X) Mount San Antonio (a.k.a. Mount "Baldy") – 10,064’/3068m – San Gabriel Mountains – USGS, HPS 
25. (Y) Zahniser Peak – 10,056’/3065m – San Gorgonio Wilderness – Not USGS, Not HPS

"USGS" indicates that the peak's name is officially recognized by the US Geological Survey
“HPS” indicates that the summit is considered a peak by the Hundred Peaks Section of the Sierra Club.

When is a peak not a peak?  Is that little bump on the side of a large peak truly a separate peak or just a knob?  Well, there's no easy answer as to what constitutes a peak.  Nobody fully agrees on exactly what constitutes a peak.  There are peaks recognized (via a name on a map) by the USGS that others would not truly consider a peak.  There are peaks that are considered peaks by local tradition, for example the "Nine Peaks" of the San Gorgonio Wilderness (San Bernardino Peak, San Bernardino East Peak, Anderson Peak, Shields Peak, Alto Diablo Peak, Charlton Peak, Little Charlton Peak, Jepson Peak, and San Gorgonio Mountain), that include peaks (Alto Diablo and Little Charlton) are not recognized by either the USGS or the HPS.  Finally there are peaks that are recognized by one government agency but not another.  For example, Bighorn Mountain is not labeled as a peak on the USGS map, but the US Forest Service officially calls the area around the mountain the "Bighorn Mountain and Whitewater River National Recreation Lands."  Again,  nobody fully agrees on exactly what constitutes a peak.  For my purposes, I've listed all high points that are either a) recognized by the USGS, b) recognized by the HPS, or c) named by local tradition.   

I hope you find this list helpful,

Notes on the elevations listed above:
In some cases, an exact height is not available for a given peak.  For example, I listed the elevation of Newton Drury Peak as 10,160+ feet/3097+ m (note the plus sign).  Given the contour lines on the USGS topo map, the exact height could be as high as 10,239'/3120m or as low as 10,161'/3097.1m.  The exact height is most likely somewhere between those two extremes, perhaps 10,200'/3109m, but the exact height has not been specified by the US Geological Survey.  Since the peak is at least 10,160'/3097m, I simply list the peak's elevation as the elevation of the highest contour line on the map followed by a plus sign.  This convention has been followed throughout.
