I noticed a small peak off Ortega Highway in the Cleveland National Forest in Caltopo with a benchmark symbol named "Stag". I searched the USGS name database and didn't find it. It also doesn't exist in the Orange County Geodetic kmz that anyone can download. All search engines turn up squat. It doesn't exist in peakbagger or lists of john. My research skills are coming up short.
Here is a map with a possible route to it from Caspers Regional Park:
http://caltopo.com/m/5B0S
My question is how did it get on Caltopo and who marked it and/or named it?
There is a higher bump on the ridge nearby and is surrounded by at least a half mile of nasty chaparral. I doubt there is a marker on it. Could it just be a Caltopo mistake?
Stag BM, who marked it?

Since it really close to the county line, check and make sure it isn't in Riverside County. You might have to check with Riverside's Public Works office to find something.
If its got a good vantage point of the surroundings it might have been put in by local surveyors as a marker, rather than using a higher , less accessable peak in the area. One of my brothers is a surveyor and has to 'find' these once in a while.

Pat,
Awesome data find! I'll add geocaching.com and the NOAA site for future searches.
This was interesting in the data sheet:
STABILITY: D = MARK OF QUESTIONABLE OR UNKNOWN STABILITY
I think it has been a long time since anyone has been there or verified the mark, but I see no reason it should not be there.

5692 ft/1735 meters makes it the second highest peak in the Santa Ana Mtns! higher than Modjeska Peak (5500 ft) and just below Santiago Peak (5900 ft)!
Well, it is certainly not 5692', it is at 2272' according to the topo. Maybe that is just bad data.
Is it possible that the "NAVD" means navigation distance instead of the actual vertical height of the mark?
The written directions for getting to it from the San Juan Station look accurate to me. There is possibly a shorter way to get to it from the Los Pinos Ridge trail, but you would have to grind through worse brush and drop down into Cold Spring Canyon and climb out of it, probably wading through dense poison oak.

Thanks again for the help in researching this.
Made the trip out there, but didn't find the benchmark. The area is very overgrown, though there were remnants of an old firebreak on the ridge. Posted a trip report here.

I did look for RM2. There was one significant outcropping just below the summit, but the rocks were somewhat broken with no one obvious biggest rock. The BM and RMs could also be under overgrowth or one of large wood rat nests. We spent about 15 minutes just looking around for marks.
If I go back, I'll make sure I have all the GPS coordinates loaded and try digging a little.
