You Can’t Run Just Part Way Up Serrano Canyon

Serrano Valley and Boney Mountain

Today’s plan was to get in around 25 miles, and like last Saturday, I was trying to keep the elevation gain down to something reasonable. I’ve been doing longer weekday runs, longer weekend runs and more days with runs. If I increased the elevation gain by the same percentage as the mileage I didn’t think I would be able to keep up with the extra training.

Today’s long run had started with a low impact 8.5 miles from Wendy Drive & Potrero road down Sycamore Canyon to the beach. That had gone well. I’d hooked up with a group training for the L.A. Marathon, and they had set a comfortable — but steady — pace.

Sycamore Canyon Campground was just beginning to stir as I ran down the access road. Warm sunlight was finding its way into the camp and other than the camp host, not many people were out and about.  Overhead a raucous gang of crows jeered a passing band of parrots, and across PCH a wave crashed on the rocky shore.



I continued running through the campground to the day use parking lot and then down onto the sand at the PCH bridge. The tide was high and from time to time whitewater from a larger wave would rush up the sand slope under the bridge and spill over the berm. I thought of bare feet on cold Rincon sand and how 55 deg water would at first feel warm on a Winter day.

With Part A of my run complete, I started thinking about Part B. If I was going to reach my mileage goal I needed to extend the return route by about 7 miles. To keep the elevation gain to a minimum, I came up with the contrived idea of doing out & backs up Serrano Canyon and Wood Canyon on the way back up Sycamore. It didn’t sound very appealing, but would add the necessary miles. Leaving the sand and seagulls behind, I started the long haul back up the canyon.

It wasn’t as cold in Sycamore Canyon as last Saturday, but with the down-canyon breeze it was still chilly in the shade. In about 15 minutes I reached the Serrano Canyon Trail and turned east up the canyon. The initial part of the canyon was quite flat and I resigned myself to the idea of running part way up the classic canyon and turning around just before reaching one of the most scenic spots in the Santa Monica Mountains.



At the landslide a half-mile into the canyon the trail steepens briefly and climbs above the creek. Just before starting up the hill I stopped to take a photo of the slide. Looking closer at one of the large boulders, I noticed it contained shell impressions and remnants similar to those found on the Fossil Trail. After snapping a photo I continued up the canyon.

Much of Serrano Canyon was in shade on this Winter morning; but in places the sun would find its way through the twists and turns of the canyon, warming me as only the morning sun can do on a cold day. With almost no water in the creek the 15 or so creek crossings in the canyon were just dips in the trail and the running was free, easy and enjoyable.

I passed the two mile turnaround point with little thought of plans, miles, races or elevation gain, and soon found myself standing on the edge of Serrano Valley’s spectacular grasslands. Rock formations on the southern flank of Boney Mountain towered above the valley and a green undercoat of Winter growth accented the trails and terrain. With a deep sigh I continued running into the Boney Mountain wilderness.

*****

I did get in my 25 miles, but not in the way I planned. From Serrano Valley I followed the Ray Miller 50K course backward, running the Serrano Valley, Old Boney, Blue Canyon, and Sin Nombre trails to the Hidden Pond Trail. There I lef the Ray Miller course and followed the Upper Sycamore Trail to Danielson Road and Satwiwa.

This route bypassed Sycamore Canyon road almost entirely and avoided the toil of having to run back up the road after just running down it. One minor issue was that when I got back to Satwiwa, I’d only run 21 miles. That was remedied by running over to Ranch Overlook and back.

Back to Mugu Peak

Hikers nearing the summit of Mugu Peak

The difference in temperature from the bottom of Sycamore Canyon to the top of the Wood Canyon Vista Trail had to be at least 30 degrees. Down on the Sycamore Canyon Fire Road the mud and mud puddles were frozen and I could feel the cold through my sleeves, shirts and gloves. In the sun near Overlook Fire Road it felt like it was a toasty 60-something degrees.

Trying to get in some less hilly miles, Craig and I were doing the run from the Wendy Drive trailhead to Mugu Peak. There would be no personal bests today. We both had long races coming up and this run would be combined with another (shorter) run tomorrow.

It’s tough to find a 20+ mile trail run in the Los Angeles area that doesn’t have much elevation gain. Wendy Drive to Mugu Peak has about 2700′ of gain. Bypassing the peak would reduce the total to around 2300′. One flatter option in this area might be Wendy Drive to PCH and back with a mile or so side trip up Wood Canyon.

Wendy Drive – Mugu Peak Challenge

Top of Mugu Peak

Running should be fun! If you’re comfortable running twenty miles (round trip) and are familiar with the trails of Pt. Mugu State Park this training “challenge” is way to get in a mix of running on pavement, dirt roads, single track trail, fast downhill, runnable uphill, and a brutal hill climb, and wrap it all up in a fun-to-solve route-finding puzzle.



The “challenge” is to run from the trailhead at Wendy Drive & Potrero Road in Newbury Park to the flagpole on the summit of Mugu Peak. That’s it — the route you use is entirely up to you, as are all other details of the run. At the top of Mugu Peak (if it’s not foggy) you’ll be rewarded with great views of the coast near Pt. Mugu, the Channel Islands, La Jolla Valley and Boney Mountain.

I ran it last Sunday. A middle-of the pack runner, my training goal was to do it in under two hours. My time was 1:55:30. Turns out my route was about a half-mile longer than what I believe to be the shortest possible route. I pushed the pace some, but have a race coming up, so didn’t go all out.

Based on my times in some similar XTERRA races I’m thinking my race pace goal should be around 1:40. A very fast runner might be able to do it in around 1:10. You’ll have to decide what’s a good goal for you. Just remember that once you get to Mugu Peak, you have to get back! (And keep an eye out for those pesky rattlesnakes and other wildlife!)

Update April 12, 2014. In near perfect weather did the peak from Wendy in 1:42:02.

Update January 5, 2014. In less than ideal conditions did the peak in 1:47:49, so it looks like 1:40 should be possible for me.

Coastline From Mugu Peak

Coastline south of Pt. Mugu from Mugu Peak. The trail wrapping around the lower peak is the Mugu Peak Trail. It leads to the La Jolla Loop and Canyon trails. There were several runners on the Mugu Peak trail, training for the XTERRA Pt. Mugu Trail Run.

From Sunday’s out and back run from the Wendy Drive to Mugu Peak.

Boney Mountain Eclipse Run

Narrative about 2012 solar eclipse

Some things in nature are supposed to be constant. The ground shouldn’t move; a mountain that is here today should be here tomorrow; and if skies are clear and blue, the sun shouldn’t grow mysteriously dim.



Imagine the consternation of our early ancestors, keenly attune to nature, feeling the sun dim and then looking for a cloud they could not find. There is still much of them in us. When the earth shakes or the sun fades, even moderately, we can’t help but react at the most visceral level.

While ee still can’t predict an earthquake with any certainty, we can predict eclipses. Fred Espenak’s NASA Eclipse Web Site includes maps and tables for several millennia of solar and lunar eclipses. Using the web site’s JavaScript Solar Eclipse Explorer you can find the solar eclipses that will be (or have been) visible at a particular location, as well as the type of eclipse, it’s magnitude, and when it will start, end, and reach its maximum. In 2002 I used the Eclipse Web site to plan a trail run to coincide with the June 10 solar eclipse. This afternoon I was doing another eclipse run — the north side loop on Boney Mountain.



Perched on rocky ledge on the western ridge of Boney Mountain, I watched as the light on the landscape became increasingly muted. At the eclipse’s maximum almost 80% of the sun’s area would be obscured and about 85% of its width. The descending veil was tangible. I could not only see it, I could feel it. Even though I understood what was occurring, and that it would not last, ancestral fears were welling up and whispering, “Something is wrong…”



As the time of maximum eclipse approached, bird songs increased as if it was dusk. The wind, which had been blowing in fits and starts began to blow steadily from the west. The temperature dropped another degree or two.

Once the eclipse’s maximum had passed, I continued to work up the ridge, enjoying the extraordinary light. I hoped my wife was getting some good shots of the eclipse in our backyard. Many eclipse viewers are so focused on the sky, they don’t notice the spectacular lensed images projected on the ground and elsewhere by sunlight filtering through trees. The gaps between the leaves of a tree work like a giant pinhole lens, with a focal length of many feet. In the case of the trees in our backyard this produced images of the eclipsed sun 10 inches or more in diameter. Lensed eclipse images were also projected by  sunlight filtering through the chaparral on Boney Mountain.

I topped out on the western ridge around 7:10 and jogged up to the high point between the western and eastern ridges. Across the way three fellow eclipse watchers were on Tri-Peaks, and it sounded like there was a party over on Sandstone Peak. Even with the sun low on the western horizon, you could feel its intensity returning. Only about one-third of the sun was now obscured, and minutes before sunset — about 7:43 — the eclipse would end.



Marine layer haze and long shadows were filling the valleys as I began the second half of my eclipse adventure — running down the eastern ridge and trying to reach the trailhead before it was pitch black. Much of the route was illuminated by the setting sun, and I was able to get past most of the technical running and down to the Danielson cabin site before it became difficult to see. Once on Danielson road the bright western sky provided enough light to run. I made good time down to the creek in Upper Sycamore Canyon and then pushed up the road to Satwiwa. Just enough light remained to run the connecting single track back to the Wendy Drive trailhead.

Boney Mountain – Serrano Valley Adventure Run

Craig running in Serrano Valley

Craig had never done any rock climbing, but was doing a great job of scrambling up the steep gullies, and climbing the short sections of knobby, low angle volcanic rock. We were climbing up through a maze of brush and rock formations on the steep ridge that follows Boney Mountain’s western escarpment. The scramble up the western ridge would be well worth the effort. The route is a shortcut to the Backbone Trail and some of the most spectacular running in the Santa Monica Mountains.



Our run had started at Wendy Drive & Potrero Road in Newbury Park. We were doing a 20 mile loop that was about as varied as a trail run can be. In addition to the 1.5 mile ascent of Boney Mountain, there would be about 13 miles of single track trail, 4.3 miles of dirt road, and even 1.7 miles of paved road.

After getting through the maze to the Backbone Trail we would do the classic run down the Chamberlain Trail to the Old Boney Trail. From the bottom of the Chamberlain Trail there are four major variations. Three of these lead to Big Sycamore Canyon and one loops directly back to the start of the climb up Boney Mountain:

– Turn left (west) on the Old Boney Trail and at the junction of the Serrano Valley & Old Boney trails follow the Serrano Valley Trail and then the Serrano Canyon Trail to Big Sycamore Canyon. This was the route we were doing today.

– Turn left (west) on the Old Boney Trail and follow it all the way to Big Sycamore Canyon.

– Turn right (east) on the Old Boney Trail and at the junction of the Blue Canyon & Old Boney trails, continue down the Blue Canyon Trail to the Danielson Multi-use area in Big Sycamore Canyon.

– Turn right (east) on the Old Boney Trail and at the junction of the Blue Canyon & Old Boney trails, turn up the Old Boney trail and  follow it  over the shoulder of Boney Mountain and back to the point where the ascent of Boney Mountain began.



In Big Sycamore Canyon there are many options. Today we would run up Sycamore Canyon Rd to Wood Canyon Rd and pick up the Two Foxes Trail. This trail continues up-canyon and eventually rejoins Sycamore Canyon Rd, which would take us to the Upper Sycamore Trail, and from there to Danielson Road and Satwiwa. Here’s an interactive Cesium browser View of a GPS trace of our route. And 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.

Note: There is an easier alternative to the western ridge route on the north side of Boney Mountain. The route starts near the Danielson Memorial, and ascends a use trail up the eastern ridge on the north side of the mountain. In places the (unmaintained) trail is very steep, eroded, and rubbly but it is more straightforward and less technical than the western ridge.
