San Gorgonio Mountain: Falls Creek Loop August 2013

Plummer Meadows on the Falls Creek Trail

Sitting on the summit of Gorgonio I shook hands with Cole and said “Hi” to his friends. They had run up Gorgonio from the Fish Creek trailhead and we were comparing notes. He’d asked how far I’d run from Momyer. I told him “about 13” and commented that I was surprised by the amount of water in the creeks. He commented, “There’s no water on the way up from Fish Creek.” I looked down, and in his pack was a gallon jug of water. One gallon of water weighs 8.3 pounds, but put it in your pack and it feels like a hundred!

Other than a Southern Pacific rattlesnake encounter and a finicky UV pen the ascent from Momyer had gone well. Alger Creek had enough water I had to pick my way across the creek, and the small streams below Saxton Camp and at Plummer Meadows had more than adequate water for filtering. The creeks were lined with with ferns and flowers and there was little hint of the past year’s meager snowpack and rainfall.

One reason might be that the on-again, off-again summer monsoon had been on much of the latter part of July. This resulted in 0.04 inch of rainfall in Downtown Los Angeles July 26 — enough for a record — and rainfall totals of over two inches in some mountain areas. The Fawnskin RAWS, at Big Bear Lake recorded 1.3 inches of rain over the period July 20-26.



The encounter with the rattlesnake had been dicey. After an hour of steep climbing on the Momyer Trail I’d turned east onto the Alger Creek Trail and was running at about 7200′ on a more or less level stretch of trail in an area of gray rocks. Earlier the possibility of a rattlesnake had flitted through my mind, but I’d become lost in a reverie of early morning sun, tall pines, cool temperatures and easy terrain.

The dark gray Southern Pacific rattlesnake might as well have been invisible. As I began an elongated stride over a large gray rock, something moved just beyond the rock. My brain registered “SNAKE!” and then a microsecond later “RATTLESNAKE!!” Adrenalin turned my already elongated stride into an awkward leap that carried me just over the moving reptile.

The snake had been sunning itself on the trail and was as startled as I was. In a panicked movement it wriggled onto a flat rock on the side of the trail and stopped. My momentum had carried me a few feet past the snake and I turned as quickly as I could to try and get a photo. Rattlesnake for sure — heavier body, triangular head with BIG venom glands. When I took a couple of steps toward the snake to get a shot, it said “no way” and slithered into an opening in the talus.



The title photo was taken at Plummer Meadows. The spot is a favorite, and the water source has never failed me. It looked no different today than in any other year. Although the stream is small, the flow was good. The area along the stream was lush and green and decorated with yellow sneezeweed, white ranger’s buttons and magenta fireweed. Tracing the path of the stream up the drainage, it lead to High Meadow Springs; about 1000′ higher and just below the divide.

The pine in the foreground of the photo is interesting. The upper part of its trunk was snapped off some years ago, probably by an avalanche in a very big snowpack year. Given the age of the tree, the big winter of 1968-69 (44 years ago) seems like the most likely candidate.

According to the California DWR report “California High Water 1968-69” during the period January 18-27, 1969, Lake Arrowhead recorded 25.66 inches of precipitation. Given the south-facing aspect and the 9000′-10,500′ altitude of the Plummer Meadows drainage, 30-40+ inches precipitation — much of it in the form of snow — is a possibility. The DWR report indicates that Mt. Baldy (village) recorded 41.6 inches of precipitation during the period January 24-27, 1969! Additional heavy precipitation was recorded in February. This could have translated to 25 feet or more of snow.

From Plummer Meadows the trail climbs about 1000′ over 1.5 miles to Dollar Lake Saddle. Much of the climb is on a well-shaded, northwest-facing slope that can be quite cool. There is a stand of limber pines along this section of trail.



The stretch from Dollar Lake Saddle to the summit is outstanding with far ranging views along and to either side of the divide. I had expected to see a pall of smoke from the Silver Fire and while the visibility wasn’t perfect, it could have been much worse. Including stops for photos and a wilderness permit check it took about an hour and a half to get to the summit from Dollar Lake Saddle. This is about normal for me and I was glad to still have some legs after doing the peak from South Fork the previous week.



How do the three trail runs I’ve done on San Gorgonio compare? Outside of the Sierra, I don’t think there is a better mountain run in Southern California that can be done as day trip than the Falls Creek Loop. The South Fork Dry Lake – Dollar Lake loop is also excellent, but the downhill running on the Dollar Lake Trail isn’t quite as good as on the Vivian Creek Trail. The Highline/Divide loop is the most adventurous and includes the most running above 10,000′, but sections of the trail below the divide are usually overgrown and you have to go off the Divide Trail to get water.

San Gorgonio Mountain: Dry Lake – Fish Creek Saddle – Dollar Lake Loop

Sky High Trail on San Gorgonio Mountain

Sky High Trail a Mile from the Top of San Gorgonio Mountain

Time flies when you’re having fun, and except for kayaking the upper Santa Ana River and a ski ascent or two, the last time I’d been on the north side of San Gorgonio was before Poopout Hill closed in 1988. Curious to refresh my memory of the area and compare a South Fork trail run to those on the Forest Falls side of the mountain, I started thinking about what would be an interesting route to do.



Running in shorts and short sleeves, I’d left the South Fork trailhead about 7:30 and was now about a half-hour into the run. Up ahead was the turn-off to Poopout Hill and not far beyond that the wilderness boundary. I’d been doing a mix of fast hiking and running and enjoying the morning. A black-capped chickadee had stopped on a branch to say hi, and a Steller’s jay was complaining loudly from the top of a pine. Earlier I’d passed Horse Meadows, an iconic scene with sunlight filtering through the trees, green meadows and rustic brown cowboy cabins.



About a quarter mile past Poopout Hill my jaw dropped as I rounded a corner and was suddenly in a sizable avalanche path. A tumult of interleaved  firs and pines lay in a hundred yard wide swath that extended thousands of vertical feet up the mountain.

This avalanche likely occurred within a few days of January 23, 2010, following (or during) a multi-day rain and snow event in Southern California. Over the seven day period from January 17 to January 23, the rain gauge at Mill Creek recorded 7.82 inches of precipitation. According to a NWS report, Mt. Baldy recorded 7′ of snow at the 8600′ level. The source area of the avalanche appears to have been in a cirque near peak 10,230.



Working up the hill toward South Fork Meadows I stopped to chat with a Ranger, who checked my wilderness permit and mentioned a group of day hikers had left South Fork very early and were ahead of me.

At the Dry Lake/Dollar Lake fork at South Fork Meadows I turned left onto the Dry Lake Trail. I already heard water, so one question was answered — there was plenty of water at South Fork Meadows. Comments on the Water Info Collector had said Lodgepole Spring was low, but “flowing OK,” so the plan was to top off my water there.



Dry Lake was indeed dry, but the meadow in its place and backdrop of sculptured mountains was still impressive. The next stop was Lodgepole Spring; I just had to find the use trail leading to it. This was one of those situations where it’s important to note the details of the topography. There are two areas that people camp at Dry Lake (noted on a sign) and the use trail is in the drainage above the second, more southerly camp.



After talking to some campers I followed the trail around the east side of Dry Lake and into the primary camping area.  After working up the drainage a couple tenths of a mile I found a small spring flowing out of some willows. Rather than taking the time to use a UV pen, I used a makeshift cup to fill a one liter  collapsible water bottle with a built-in filter. Hopefully that, and what was left in my pack, would get me up to the peak and back down to South Fork Meadows.



The “use” trail from Lodgepole Spring was not too difficult to follow and it took about 30 minutes to get up to Fish Creek Saddle. The trail between Fish Creek Saddle and Mineshaft Saddle more or less follows the 9880′ contour line and was reasonably runnable. It passes through an area of lodgepole pines killed by the mountain pine beetle.



In a few minutes I rejoined the regular Dry Lake route at Mine Shaft Saddle and started up the increasingly scenic Sky High Trail. About a mile up the trail from Mine Shaft Saddle is wreckage and a memorial to the personnel of a Douglas C-47 that crashed in a snowstorm on December 1, 1952. The C-47B “Gooney Bird” was a military version of the venerable DC-3 airliner.

The Sky High Trail earned its name as it switchbacked up to 11,000′, and wrapped around the south side of Gorgonio’s summit. From the  airy trail there are stunning views past The Tarn to Banning Pass and Mt. San Jacinto. The Sky High Trail joined the Divide Trail a little east of the Vivian Creek Trail junction and in a couple of minutes I was jogging east across the summit plateau to the blocky summit of San Gorgonio Mountain.

According to the Trail Mileage Handout (PDF) from the San Gorgonio Wilderness Association the descent from the summit by way of Dollar Lake Saddle and the Dollar Lake Trail is about 10.7 miles — which is a little shorter than the 11.4 miles listed using the regular Dry Lake route. (Mileage doesn’t include the side trip to Lodgepole Spring.) Even so, I think the Dry Lake route is the preferred route from South Fork Meadows. It’s more scenic and aesthetic.



The running was technical, but good down to Dollar Lake Saddle. Below Dollar Lake Saddle the trail was often very rocky. This lightning-scarred pine was on one of the last switchbacks before South Fork Meadows. I was happy to get down to South Fork Meadows, get some water, and get onto a better trail! By about 3:30 pm I was back at the car and enjoying an ice cold bottle of water.

Bigcone ENSO Prediction, Poodle-dog Bush Blues, and a Surprise on Kenyon Devore

Morning sun on the dome of the Mt. Wilson Observatory

I’d paused to rinse my arms and legs, hoping to wash away at least a little of the poison oak and Poodle-dog bush I’d been unable to avoid. I was at a small spring part way up the Kenyon Devore Trail, doing a variation of a loop that my son and I had done a year before.

Today’s run had started on the top of Mt. Wilson, descended the Rim Trail to Newcomb Pass then followed the Gabrielino Trail down to the Rincon – Red Box Road. This year instead of taking the forest road down to West Fork, I stayed on the Gabrielino Trail and descended to Devore Camp, and then worked back upstream on the Gabrielino Trail past West Fork to the Kenyon Devore Trail.



Driving up the Mt. Wilson Road I’d noticed that many of the bigcone Douglas-firs were heavily laden with cones. According to the Forest Service’s Silvics Manual bigcone Douglas-firs don’t often have bumper crops. Why now, following two subpar rain seasons, the most recent of which was unusually dry? Was the tree’s evolutionary knowledge playing the odds that a wet period of Southern California’s wet/dry ENSO cycle is a Winter or two away? At the moment La Nina or Neutral conditions look more likely this coming Winter, but the odds for El Nino could increase for the Winter of 2014-15.

Update June 25, 2018. El Nino conditions did emerge in late Fall 2014 and continued until the Spring of 2016. However, the drought in Southern California persisted and below average precipitation was recorded in both 2014-15 and 2015-16. It wasn’t until the 2016-17 rain season (during a weak La Nina) that Southern California received above average precipitation.



Like last year there was plenty of poison oak and Poodle-dog bush along the Rim and Gabrielino Trails. The poison oak was about the same as last year — mostly but not entirely avoidable — but the Poodle-dog seemed worse. I’d hoped that this year’s much lower than average rainfall would suppress the growth of Poodle-dog bush, but if anything it seemed more robust. Poodle-dog had overgrown the trail in several spots, its long stalks and sticky leaves overlapping the trail like a gauntlet of pikes. Contact was unavoidable.



It had been interesting to visit Devore Camp. The last time I’d been there was in March 2003 when Gary Gunder and I paddled from the West Fork San Gabriel River from West Fork to Hwy 39. We had been fortunate to be able to paddle the reach with few portages. With all the downed trees from the Station Fire it may be many years before big storms flush the river channel to point it can be paddled without logs being a constant problem.



In addition to the expanses of Poodle-dog bush blossoms, a number of other wildflowers were in bloom, including Grinnell’s beardtongue, rose snapdragon, blackberry, pink, paintbrush, bush poppy, buckwheat, gilia, Keckiella and others. Along the West Fork the blossoms of spotted Humboldt’s lilies had beamed like yellow-orange paper lanterns scattered throughout an immense garden.

I cannot ascend the Kenyon Devore Trail without thinking about the Mt. Disappointment 50K/50M. During those races the little spring I was at now had always been a welcome source of “extra” water on the final climb to Mt. Wilson. The 2013 races have been cancelled, but are expected to return in 2014. We all know how tough R.D. Gary Hilliard is and look forward to next year’s race!

“Hey, are you on a trail?”

The voice seemed to come from nowhere. I looked to my left and right, but the trail was empty.

“Hey, up here!”



What the… I scanned the STEEP slopes above the creek, but still had a hard time locating the voice. After a moment of rustling, a helmeted figure emerged from the trees, carrying an orange mountain bike.

If you’ve done the Kenyon Devore Trail as part of the Mt. Disappointment races or at another time you probably recall the slippery stream crossing with the chain. The MTBer had apparently missed a switchback about a mile up the trail and descended directly down a ridge to the spring.

Update Friday, June 21, 2013. Lucked out with the Poodle-dog bush* and poison oak! Just one small spot of irritation on the top of an ankle, and it’s already almost gone.

*The taxonomic name for Turricula parryi (Poodle-dog bush) has changed to Eriodictyon parryi. The Jepson Manual: Vascular Plants of California, Second Edition (2012) has returned Turricula to the genus Eriodictyon, as originally described by Gray. According to the Wikipedia entry for Turricula (April 11, 2012), “… molecular phylogenetic analysis carried out by Ferguson (1998) confirms that Turricula should be treated as a separate genus within a clade (Ferguson does not use the term “subfamily”) that includes Eriodictyon, and also the genera Nama and Wigandia; Eriodictyon is the genus to which Turricula is closest in molecular terms, and is its sister taxon.” I use “Turricula” and “Poodle-dog bush” interchangeably as a common name.

Coast Redwoods Along the French Trail in Redwood Regional Park

Coast redwoods along the French Trail in Oakland's Redwood Regional Park.

Coast redwoods are spectacular trees, often growing to more than 200 feet tall. They can attain phenomenal size. According to Famous Redwoods, the tallest is the Hyperion tree in Redwood National Park, with a height over 380 feet. The 2021 National Register of Big Trees lists the Lost Monarch in Jedediah Smith Redwoods State Park as the Champion coast redwood. It has a circumference of 950 inches (79.2 feet). There are reports of even larger coast redwoods.

Here’s a Calflora/Google Maps image and live link of the distribution of coast redwoods in California. The southernmost naturally-occurring coast redwoods are in Monterey County, in the Southern Redwood Botanical Area of Los Padres National Forest.

The title photo is of coast redwoods along the French Trail in Oakland’s Redwood Regional Park and is from a hike in mid-May.
