Serrano Valley from Wendy Drive

Descending to Serrano Valley in Pt. Mugu State Park

Scruffy clouds clung to the mountain ridges and summits, confirmation that a weak cold front was moving through the area, cooling temperatures and stirring up the wind. The forecast for the Santa Monica Mountains National Recreation Area had mentioned 25 to 35 mph winds with gusts to 60 mph. So far the weather in Pt. Mugu State Park had been nearly perfect — breezy and little chilly, but without the impenetrable winds that can take all the joy out of running.

Earlier we had climbed the Fossil Trail, a steep mile-long trail that connects the Upper Sycamore Trail, near its junction with Sycamore Canyon Road, to the Old Boney Trail. With only a few weeks remaining to the Solstice, shadows in the canyon were long and the light wintery. I thought we might have missed the fossils, but we happened on a nice exposure about a tenth of a mile below the Old Boney Trail junction.

About 5.5 miles later, we turned off the Old Boney Trail and descended to the rolling grasslands of Serrano Valley, another “must see” area of the Santa Monica Mountains.

Located on the east side of Big Sycamore Canyon, Serrano Valley is a more rugged counterpart to La Jolla Valley, just three miles to the west. Overseen by the castle-like summits of Boney Mountain, its vistas have a roughhewn edge, reminiscent of the most wild areas of the western U.S.

Here is a Google Earth image and Google Earth KMZ file of a GPS trace of our approximately 19 mile route to Serrano Valley and back to Wendy Drive.

T-storms and Trail Work

Old Boney Trail in the Boney Mountain Wilderness

When I woke to the rumble of thunder, rain pounding the roof, and wind roaring in the trees, I wondered if a planned run of the Boney Mountain Half Marathon course with John Dale was going to turn into an epic. Radar and satellite imagery showed subtropical moisture streaming in from the southwest, producing bands of showers and thunderstorms. Things don’t always look as bad at the trailhead as they do on weather radar, so I grabbed my gear and headed for Wendy Drive.

The weather looked promising driving through Agoura, but the further west I drove, the more ominous the skies became. Somewhere around Lynn Road KNX announced that the NWS had issued a severe thunderstorm warning for the Santa Clarita area, with cloud to ground lightning, heavy rain, possible damaging winds and dime-sized hail. It was with that thought in mind, and a shower pelting the car, that I pulled into the parking area on Potrero Rd.

If anything, weather is fickle, and sometimes that quirkiness can work for you. There was an area of heavy rain to the west, but the activity appeared to be skirting the area, so we opted to start the run.


Thunderstorm marching northeast from the Santa Barbara Channel across the Oxnard Plain.
There were a few sprinkles as we jogged down the blacktop into Big Sycamore Canyon, and a few more as we did the first easy mile of the Hidden Pond Trail. Down in the canyon it was hard to tell what the weather was doing, but after gaining some elevation we reached a better vantage point. Just a few miles away thunderstorms were being swept northeast from the Santa Barbara Channel, across the Oxnard Plain, and into the Ventura Mountains.

Skies darkened and the shower intensity increased as we ran down Ranch Center Fire Road. The wind was blowing in the fitful gusts that precede a thunderstorm, and it felt as if the sky might fall at any moment. With a slight shift in the track of the thunderstorms we might be running in a deluge, dodging lightning strikes.

But it didn’t shift. Following the shower, the sun broke through the clouds just long enough to add glints to the raindrops dripping from the leaves of sycamores and oaks in Blue Canyon. Under overcast skies, we climbed up the Old Boney Trail and into the Boney Mountain Wilderness.

We had not seen a hiker, runner, or rider since turning onto the Hidden Pond Trail early in the run. So it was a bit of a surprise when we rounded a corner and ran into Ed Reid and several other volunteers with the Santa Monica Mountains Trails Council doing trail maintenance on a section of the Old Boney Trail.

Just about any weekend of the year, dedicated members of the SMMTC will be somewhere in the Santa Monica Mountains, working on a trail. To get a better idea of the amount of work done and the number of trails involved, take a look at this list of recently maintained trails! How many of these have you hiked, run or ridden?

There are several ways to help support SMMTC:

  • Volunteer to do trail maintenance.
  • Join the SMMTC.
  • Make your REI purchases using the REI link on the SMMTC web site. REI will donate a percentage of the purchase to SMMTC.

La Jolla Valley & Mugu Peak from Wendy Drive

Pt. Mugu from Mugu Peak.

The scat appeared to be a day or two old, and was much bigger than a coyote’s. It was full of fur and could only be from one animal — a mountain lion. The spot had been used before, and it probably wasn’t a coincidence that this was one of the few points along the trail with a good view and nearby cover. I looked into the brush and wondered if unseen eyes looked back.

The sun was well above the horizon, but the first gusts of a developing Santa Ana wind kept the morning cool. No one was on the trail ahead or behind me, and the best I could tell, I was the only two-legged creature within sight.


Spring in La Jolla Valley. Boney Mountain in the distance. March 2002.
Walking slowly from the spot, I surveyed the secluded valley. Perched on the edge of the coastal mountains, La Jolla Valley is extraordinary. Surrounded by wind-sculpted peaks, it is situated above and to the west of Big Sycamore Canyon. Its bottom is carpeted with areas of native and non-native grass. Only a tiny percentage of California’s native perennial grasslands remain, and like the big trees, they are relics of the past. Preservation of this native grassland is probably due to the valley’s proximity to the ocean, and its unique microclimate.

Here, trails have been run and peaks climbed for thousands of years. (Charcoal at an archaeological site in the valley has been dated to a maximum age of 7000 B.P.) Above me a raven calls, and Spirit-like, a gust of wind rustles through the grass. Respectfully, I continue running in the direction of Mugu Peak.

The run from Wendy Dr. was more moderate than expected. The first 3 miles of Sycamore Canyon Fire Road are paved, and whether on the fire road, or the single track trails that parallel the road at times, a fast pace can be maintained down to the junction with Wood Canyon Fire Road.

The Wood Canyon Vista Trail/Backbone Trail takes off right (west) from Sycamore Canyon Fire Road a short distance past the Wood Canyon Fire Road junction. It is moderately graded and very runnable. At it’s top a short zig right (north) on the Overlook Fire Road leads to the La Jolla Valley Fire Road, which can be followed left (west) down into La Jolla Valley.

Many, many variations of this course are possible. Here are archived maps of Rancho Sierra Vista/Satwiwa and Pt. Mugu State Park originally from the NPS Santa Monica Mountains web site. Also see the Pt. Mugu State Park maps on VenturaCountyTrails.org.

Depending on whether you want the beta, a little time in Google Earth should help clarify the options. This particular course worked out to about 21 miles, with about 2200 ft. of elevation gain/loss. Here’s a Google Earth image and 3D interactive view of a GPS trace of my route.

Boney Mountain – Big Sycamore Canyon Circuit – Coyote Trail Variation

https://photographyontherun.com/content/binary/BoneyMountain1000130b.jpg

It’s fun to link together several trails into a loop, and it’s even more fun when the trails are single-track, or at least have a single-track flavor. The Boney Mountain – Big Sycamore Canyon circuit links together segments of more than ten trails and roads in Rancho Sierra Vista/Satwiwa and Pt. Mugu State Park. The route is characterized by airy ridges, steep climbs, wide-ranging views, towering rock formations, and one of the best downhill running segments in the Santa Monica Mountains. Today’s run expanded the loop, adding even more single-track trail — and elevation gain.

This route also climbs over Boney Mountain and descends the Chamberlain Trail segment of the Backbone Trail. However, at the Old Boney Trail junction, instead of descending to the Danielson multi-use area on the Old Boney Trail (northbound) and Blue Canyon Trail, this route follows the Old Boney Trail (westbound) to Sycamore Canyon Fire Road.

From the junction of the Old Boney Trail with the Sycamore Canyon Fire Road the goal is to hook up with the Coyote Trail, which can be seen switchbacking steeply up a slope on the other side of the canyon. We did this by continuing about 0.5 mile down Sycamore Canyon Fire Road, and then turning right on Wood Canyon Fire Road. The Two Foxes Trail starts a short distance up the fire road, and in about 0.4 mile leads to the start of the Coyote Trail. Once on the Coyote Trail it is about 2.3 tough — and often hot — miles to the start of the Hidden Pond Trail at Ranch Center Road. The rest of the route is the same as in the Boney Mountain – Big Sycamore Canyon circuit.

All in all the course is about 21 miles long, with 4000 ft. of elevation gain/loss. Here’s a Google Earth image and Google Earth KMZ file of a GPS trace of the route.

Mt. Disappointment 50K 2008 Notes

North face of Strawberry Peak from near the junction of the Strawberry and Colby Canyon trails.

Note: The Mt. Disappointment Endurance Run is now the Angeles National Forest Trail Race.

Updated 8/05/09. Added browser view of GPS trace of the course. Uses Google Earth plugin.

Updated 8/20/08. Added Split Rank listings (PDF) for 2007 50K and 50M, and related comments.

Winding down the precipitous Mt. Wilson road, I thought about the run ahead. To my left granite and pine glowed golden in the morning sun, and to my right the mountain plunged in long shadows, 2000′ into the canyon of the West Fork San Gabriel River.

In a few hours I would be somewhere down in that canyon, plodding along sun-baked Red Box road. By then the temperature would be in the mid-eighties, but in the full sun it would feel like a hundred. That would be around mile 23. I kicked a pebble and winced as it almost hit the heel of the runner in front of me. Only at mile 1-something, there were a lot of miles to go.

This was the fourth running of the Mt. Disappointment 50K, and my fourth as well. If ever a race route mirrored the character of its organizer, the Mt. Disappointment Endurance Runs reflect the tough and tenacious character of race director Gary Hilliard. Starting and ending near the summit of 5710′ Mt. Wilson, the figure-8 50K course is a challenging mix of mostly single track trails and dirt roads with an honest 5800′ of elevation gain/loss. A very difficult 50 mile option was added in 2007, and is a favorite of runners training for the Angeles Crest 100.

Even for the experienced trail runner, the Mt. Disappointment 50K is no gimme. Consider the following stat:


Nearly half (44%) of the 5800′ of elevation gain is in the last 5.3 miles of the 31.5 mile race!

Did you push the downhills too hard? Not eat enough? Electrolytes low? Whatever miscalculations have been made earlier in the race will be rung up here — ka-ching! The runner that has nothing left for this climb can take hours to complete it.

One possible gotcha is that 8.6 miles of the first 11 miles are downhill, and it is very difficult to resist being swept along by gravity and the crowd. The early enthusiasm of surrounding runners is contagious.  In 2007, I pushed the pace to Clear Creek too hard, and bonked on the backside of Strawberry Peak. I could barely run. The uphill stretch on the Strawberry Trail to Lawlor Saddle seemed to go on forever, and even the downhill to Red Box was hard to run. I didn’t see how I could finish the race.

How bad did it get? Out of curiosity I used the splits from the 2007 race to calculate each runner’s rank at each aid station, as well as their time between each aid station. At Clear Creek my rank was 58th, and by Red Box it had blossomed to 82nd. That means between Clear Creek and Red Box I was passed (and encouraged) by 24 runners. Here are the calculated 2007 50K Split Ranks and the 2007 50M Split Ranks. Some splits were missing and had to be estimated — these could be wildly inaccurate.

I did finish, but it wasn’t fun. This year I was determined not to repeat that experience. The plan was to be about 10 minutes slower at the Clear Creek aid station; gain back that time, and more, by Red Box (Aid #3); run the Red Box Rd. segment in about an hour; and then do the final climb back to Mt. Wilson in about 1:40. That would put me closer to my 2005 and 2006 times.

Here are some notes from along the way. Times are from aid station to aid station, and are approximate.

Mile 0 to 5.7 (Red Box Aid #1): Kept the pace easy on the paved road down to Eaton Saddle. Didn’t push the climb up Mt. Disappointment, or on the steep, switchbacking trail down to the Mt. Wilson road. 2007: 59 min 2008: 66 min

Mile 5.7 to 10.8 (Clear Creek Aid #2): Continued to hold back some on the pace down the old roadbed to Switzers. Felt good on the short climb from Switzers to Clear Creek and passed a couple of runners. 2007: 58 min 2008: 63 min

Mile 10.8 to 21.2 (Red Box Aid #3): Ran some of the more gradual uphill stretches on the Josephine Fire Road, but walked the majority of it. Passed a few people. The average grade of the 2.8 mile segment up the Josephine Fire Road is about 520 ft./mile, which is somewhat less than Kenyon-Devore’s 616 ft/mile. Enjoyed some watermelon and chips at the “water only” aid station at the top of the climb (mile 13.4). Time up the hill was 43 minutes — about the same as in 2007. Unlike last year was able to run and enjoy most of the Colby Canyon Trail, as well as the downhill from Lawlor Saddle to Red Box. The uphill stretch from the Colby Canyon Trail JUnction to Lawlor Saddle was still a long — and warm — 1.8 miles. Its average grade is about 411 ft/mile. 2007: 172 min 2008: 150 min

Mile 21.2 to 26.2 (West Fork Aid #4): In previous years this section has been the most difficult for me, and it was again this year. I could whine about the heat, but I think this is where extra training miles would make a big difference. I was happy to see the creeks running again this year, and stopped a couple of times to dump water on my head. Ahhhh… 2007: 66 min 2008: 61 min

Mile 26.2 to 31.5 (Finish on Mt. Wilson): By the time I got to the West Fork aid station, I was ready for something other than downhill. At the aid station I gulped down three cups of defizzed Coke and some water, and refilled one bottle with Heed and the other with ice and water. I still had two GU’s for quick energy later in the climb. I was able to run part of the 1.5 miles up the canyon to where the Kenyon DeVore trail splits from the Gabrielino trail, and the 3.1 mile Kenyon-Devore trail went well. Many of my long trail runs this Summer — in the Sierra, San Gabriels and on San Gorgonio — have been on steep terrain, and that, along with a slower start, probably helped here. 2007: 112 min 2008: 100 min

Overall, my time was 27 minutes faster than in 2007. But that’s just a figure on paper and doesn’t begin to describe how much better I felt during the race, and how much more I enjoyed it. Start slow, start slow, START SLOW is an ultrarunning adage we all know, but in the fervor of race it is often one of the first maxims that is forgotten.

Again this year, Gary Hilliard and crew made sure everything was just so — trails, aid, awards, finish line food, 2000 lbs. of ice, Brooks t-shirt, goody bag and more. Always an adventure, the Mt. Disappointment 50K is a trail running classic. Many thanks to all that make it happen!

The title photograph was taken at about mile 17.5 on the course, just past the junction of the Strawberry and Colby Canyon trails, and is looking back at the terrain traversed by the Colby Canyon Trail on the north side of Strawberry Peak. It is from November 2007.

P.S. About 20 minutes after I finished the 50K, Jorge Pacheco completed the 50 mile race in an astounding 7:41, crushing the course record he set last year by almost 45 minutes! Full results are posted on the Mt. Disappointment Endurance Runs web site.

Islip Saddle – Mt. Baden-Powell South Fork Loop

View of the South Fork Big Rock Creek and Devil's Punchbowl from Mt. Baden-Powell.

Maybe it’s because it’s been in the news recently,  but when pondering how to characterize today’s trail run, I couldn’t help but think of the JFK quote, “We do these things not because they are easy but because they are hard…” This loop is arduous, adventurous, and challenging. While the difficulty of this route is one of the things that makes it interesting, it isn’t just the difficulty that makes it appealing.

Part of the appeal is the mix of trails and terrain, and the contrasting environments. The high point of the route is 9,399′ Mt. Baden-Powell. Cool, airy and alpine, it is the home of ancient Lodgepole and Limber pines. The low point of the route is 4,560′ South Fork Campground. On the margin of the Mojave Desert, it is often hot and sometimes torrid. Midday temperatures here can reach well over 100°F. The route encompasses life zones ranging from the Upper Sonoran to the Hudsonian, and passes through a variety of plant communities. The San Andreas Fault Zone runs along the base of the mountains, torturing the area’s rocks, and producing a complex and fascinating geology.


Erosion gulley on the Manzanita Trail.
From Islip Saddle the route descends the South Fork trail to South Fork Campground, then climbs 5000′ on the Manzanita and Pacific Crest trails to the summit of Mt. Baden-Powell. From here it follows the PCT back to Islip Saddle. In general, the part of the route that is on the PCT — above Hwy 2 — is well marked and maintained. However, on the South Fork and Manzanita trails — below Hwy 2 — you are on your own.

There are rock slides on the South Fork trail, and there are steep, washed out erosion gullies on the Manzanita trail. Recent thunderstorms have further damaged the eroded sections of the Manzanita Trail. In addition, the Manzanita trail crosses boulder-strewn washes that can make the trail difficult to follow. It is not a trail I would want to be on when there is heavy rainfall. The South Fork and Manzanita trails are part of the High Desert National Recreation Trail.
