Ascent Trip Report

On December 19, 2015, I “cleaned out” as many peaks as I could driving the Cleghorn Ridge Road and the Cleghorn Road in their entirety.

For Cleghorn Peak, I left northbound I-15 at Cleghorn Road, right a right at the exit and drove right on to the Cleghorn Ridge Road. I parked at a location approximately 7.2 miles from the freeway, on what looked like one of the various OHV trails. Room for a few vehiccles. The coordinates were 34.29414° N and 117.41427° W. Cross back over the road, negotiate the wire fence, and proceed steeply east up the hill along a use trail. At the top of the hill turn left (north) and proceed to the high point. Return the way you came. It’s about 7.1 miles from the parking spot to SR-138.

Southbound on SR-138 from I-15 at Cajon Junction, once you reach the Cleghorn Ridge Road, it’s 1.5 miles to the Cleghorn Road. From there, it’s about 6.2 miles to the Cajon Road turnoff, usually gated. Park there for Cajon. While the HPS peak guide says to hike to a saddle and go up from there, the better route is to hike to a point about .15 miles below the lookout site (marked on the map as Cajon Mountain and now adorned with some weather equipment, and a good destination as well), and find a small cairn at around 34.27185° N, 117.42224° W. Follow a reasonably-well-clipped use trail to the summit, where there is a register. Return the way you came. (See the GPS track as well.)

Stats for Cajon from the Cleghorn Road (including a visit to the lookout site and a false start before I found the use trail):

Mileage: 3.72
Total time: 2:03:46
Moving time: 1:34:24
Overall speed: 1.81 mph
Moving speed: 2.37 mph

Next, I followed the Cleghorn Road to the turnoff for Sugarpine, and did the easy roundtrip.

Next, consultants on the Cleghorn Road, I parked at the base of Bailey, did the quick jaunt up to tag Bailey and sign the register, then back down past my car and walked the short distance to the gate for the Bailey Benchmark. A short walk brings you to the communications site, and the obvious rocky highpoint contains an actual benchmark.

From here, I think the formal name of the road is now the Bailey Mountain Road, and it was on to Peak 5598. I parked as close to the peak as I could, then followed an obvious gully up (west). As is often the case on these obscure unnamed peaks, there are a plentitude of use trails. I opted for the most direct route, and after making a lot of progress eventually ran into brush and buckthorn that was pretty tough to get through. I started clipping but got discouraged, and after a couple of nearby options didn’t work, eventually retreated. I was glad I did, and eventually made my way around to the north of the peak, and came all the way around to the backside from the northeast. I found the summit, marked with a small cairn and a wine bottle, but no register. I thought it might be easier to continue clockwise around the mountain instead of retreating, but that was a mistake, and eventually had to backtrack all the way. So, if you want this to be as easy as possible, go up the gully and then avoid the brush to the north. All my various meanderings from the truck totaled less than a mile.

On to Monument, which was super easy. I then took the road to a place marked on the map as Pine Flat. Getting to Point 5099 was easy enough, but my thoughts of getting to BM Flat (5066) were foiled by heavy brush and brush-fatigue.

Back in the truck, and took the road (rough at times) all the way down to Palm Avenue in San Bernardino, from where it was easy to get back on the 215, and on my way home.

HPS Peaks: 5
