Out and Back Trail Run to the Ray Miller Trailhead from Wendy Drive

Hikers enjoy the spectacular scenery of California's Point Mugu State Park

When I parked at the Wendy Drive trailhead, there was just enough light to see a wide band of high clouds overhead. That was good news. With a well-advertised storm expected to move through the area the next day, I hadn’t been sure what weather to expect for today’s run.

The general forecast was for low clouds and fog in the morning, giving way to partly cloudy skies in the afternoon. I was going to be running one of the more scenic trails in the Santa Monica Mountains — the Ray Miller Trail. High clouds and sunshine were a much better option than running in the fog or with gloomy, overcast skies.

Shortly after leaving the trailhead, the band of high clouds became underlit by the reds, oranges and yellows of the rising sun. It was going to be a good run.

The route-finding on this run is relatively straightforward. From the Wendy Drive trailhead on Potrero Road, run over to the Satwiwa Native American Indian Culture Center (see Satwiwa map). From the Culture Center run 4+ miles on Big Sycamore Canyon Road/Trail toward the beach. Some of this is paved.

Once past the junction of Sycamore Canyon and Wood Canyon fire roads, take either the Wood Canyon Vista Trail (Backbone Trail) or Fireline Trail up to the Overlook fire road. From the top of the Wood Canyon Vista Trail turn left on Overlook fire road, or from the top of Fireline turn right, and follow the road to the top of the Ray Miller Trail. The Fireline option is about 0.4 miles longer. Here’s a map from the State Park website. Note that the La Jolla Canyon Trail is closed.

The Ray Miller Trail drops about 1000′ over 2.6 scenic miles. There is usually water available at the parking lot at the trailhead. Today the conditions were about as good as they get. The trail was in excellent condition. The temperature was in the mid-70s. The marine layer was holding offshore and a few puffy clouds had formed over the higher peaks.

One of the things about the Ray Miller Trail is that run/hike up it is almost as enjoyable as the run down. It is a very popular, and there are almost always runners and hikers on the trail. Running up a section of trail, I thought I recognized someone going down. It was nine-time Badwater finisher Chris Frost. We talked for a while about trails, running and races.

From Overlook Fire road the route back to Wendy was a familiar one — Hell Hill, Wood Canyon Fire Road, Two Foxes Trail, Big Sycamore Canyon Road, Upper Sycamore Canyon Trail, Danielson Road, and the Satwiwa Loop Trail. Including a short jog over to PCH the run was a little over 24 miles with about 3100′ of elevation gain.

Fogbow Near the Top of Hell Hill in Pt. Mugu State Park

Fogbows form opposite the sun in a manner similar to rainbows, except the water droplets that create a fogbow are much smaller than raindrops. Because a fog droplet is so small, the physics of the interaction is different. The result is often a diffuse, primarily white bow.

The photograph of the fogbow was taken Sunday morning on an out and back run from Wendy Drive to Mugu Peak. The sun was about 14 degrees above the horizon. More about fogbows and other atmospheric phenomena can be found on Les Cowley’s Atmospheric Optics website.

Cool Running at Ahmanson Ranch

East Las Virgenes Canyon Trail in Upper Las Virgenes Canyon Open Space Preserve

Hikers, riders, and runners reveled in the unseasonably cool afternoon temperatures at Ahmanson Ranch (Upper Las Virgenes Canyon Open Space Preserve) yesterday.

According to the NWS, the high temperature of 75 degrees at Woodland Hills (Pierce College) was the lowest for the date on record. The temperature at the Cheeseboro RAWS didn’t reach the 70s until around 1:30 p.m., and finally hit 75 around 4:30 p.m. Earlier in the day, the station recorded 0.03 inch of light rain.

I took advantage of the cooler weather to do an out and back trail run from the Victory Trailhead to Cheeseboro Canyon. The nine mile run has an elevation gain/loss of around 1000′. Except for a couple of hills, it’s a relatively fast-paced route, particularly on the way out to Las Virgenes Canyon. There are two creek crossings in Las Virgenes Canyon. These dried up earlier this year, but in some years the crossings have enough water to get your shoes wet.

It’s not a good run to do when it’s hot, and in the Summer Ahmanson is almost always hot. In-the-sun temperatures are typically above 100 degrees, and sometimes reach 110 degrees or more. More than once I’ve encountered people on Ahmanson area trails that misjudged the conditions and were out of water. And sadly, dogs are especially susceptible to heat.

Here’s an interactive, 3D terrain view of the run. The map can be zoomed, tilted, rotated, and panned. To change the view, use the control on the upper right side of the screen. Track and placename locations are approximate and subject to errors. Poor weather, and other conditions may make this route unsuitable for this activity.

Those that recreate at Ahmanson will recognize the title photo as East Las Virgenes Canyon, about 1.1 mile from the Victory Trailhead. This is where a trail/road to Lasky Mesa forks off the main road.

San Bruno Mountain and Windy Hill Trail Runs

With vaccinations on the increase and Covid on the decline, it was wonderful to once again be able to visit family.

As we always try to do, Brett and I got in a couple of runs. We usually do at least one run that is new to me, and there are certainly plenty from which to choose in the Bay Area.

Our first run was on San Bruno Mountain. We’d previously done the Ridge Trail, so this time opted to do a variation of the Summit Loop. The parking lot at the base was was closed, so we started the run using the Old Ranch Road Trail. This was a plus because it added a little mileage and there were a lot of wildflowers along the trail, including monkeyflower, iris, lupine, yellow paintbrush, daisy, and foxglove.

It was an excellent run on single-track trail. As is the rule on San Bruno, it was a bit breezy, with hazy views of the surrounding communities and the Pacific. An island of open space in an urban sea, San Bruno Mountain is a miracle of land conservation, and an area to be relished. Here is a map of trails in the area.

The next day, after watching a spirited youth soccer match, we headed south on 280. On the way, Brett filled me in on the runs he likes to do in Windy Hill Open Space Preserve and Huddart Park. We couldn’t go wrong with either choice but finally decided to save Huddart Park for another day.

Windy Hill Open Space Preserve is on the northeast-facing slopes of the Santa Cruz Mountains above Portola Valley. We parked near the Alpine Trailhead and ran up the road to the Eagle Trail. Corte Madera Creek was running, but low. Although the grasses along the trail were green and the undergrowth was relatively lush, I suspect the conditions were more like July than May. Open hillsides looked mid-Summer dry and the lichen on the trees was drab and desiccated.

Like the rest of California, the Santa Cruz Mountains have seen well below average precipitation this rain season. One station near Windy Hill, Woodside 3.4 S, recorded only about 28% (12″) of normal precipitation from October 1 to May 19. Another station, Skyline Ridge Preserve, recorded about 41%  of normal (16.5″) from October 1 to May 3.

From the Eagle Trail/Private Road we turned onto the Razorback Ridge Trail. According to my Garmin track, the Razorback Ridge Trail gains 1000′ or so over 2.4 miles to its junction with the Lost Trail. It’s all runnable, switch-backing up a thimbleberry and fern-lined trail, shaded by California bay trees.

While the Razorback Ridge Trail continues up another 0.4 miles to Skyline Blvd., we turned right onto the Lost Trail. This trail parallels Skyline as it works in and out of the tributary ravines of Jones Gulch, on its way over to the Hamms Gulch Trail. Along the way there were views across the valley to Mt. Diablo, some 40 miles distant. Western columbine was blooming along the trail, its bright red color complimenting the green theme.

At the top of Jones Gulch, there is an impressive, old-growth Douglas-fir. At chest height, it is about as wide as Brett is tall. This would put its diameter at over 72″ and its circumference at over 220″, suggesting an age in the neighborhood of 350 years.

The run down the Hamms Gulch Trail was as good as the run up Razorback Ridge. Given the weather was nearly perfect for a hike or run, we were surprised to see only a dozen or so people on the trail.

From where we were parked the run worked out to about 8 miles, with about 1500′ of gain/loss. Here is a trail map of the area, and here is an interactive, 3D terrain view of my GPS track of the loop.

Return to Ross Mountain

South Ridge of Mt. Baden-Powell about a mile from Ross Mountain

When I started up the trail from Vincent Gap (6585′), the thermometer on my pack read 36°F. For the first few switchbacks, the trail was immersed in cloud. Beneath the tall conifers, the sandy soil was dotted with droplets of moisture extracted from the fog.

I was on my way to Ross Mountain (7402′), one of the most isolated peaks in the San Gabriel Mountains. At the end of a rugged, 3-mile ridge extending south from the summit of Mt. Baden-Powell, the peak overlooks the vast canyons of the Sheep Mountain Wilderness.

This morning, the canyons were filled with a 7000′ deep layer of stratus clouds. With a weak upper low over the Southern Sierra, the question of the day was whether the cloud deck would work up the ridge from Ross Mountain and completely envelop Baden-Powell.

Well acquainted with the trail up Baden-Powell, a combination of fast-hiking and slow-jogging put me on top in a relatively comfortable 90 minutes. I’d tried not to overdo the pace, knowing from previous experience that the return from Ross Mountain would be the tough part of the day.

From the summit of Baden-Powell, I gazed across the sea of clouds to Mt. Baldy. There was almost no snow on its steep north face. San Gorgonio Mountain was visible in the haze to the left of Pine Mountain and San Jacinto Peak in the gap between Dawson Peak and Mt. Baldy.

Walking a little down the south side of Baden-Powell, I got my first good look at the South Ridge. Ross Mountain was nearly covered in clouds. Guessing that the deck of clouds might deepen, and a few minutes might make the difference of being in the clouds or out, I started to jog-lope-shuffle down the initial steep slope.

The title photo was taken a bit past Peak 8375, about 1.7 miles from Baden-Powell and 1.2 miles from Ross Mountain. At that time the clouds were spilling over the ridge near Peak 7407 and Peak 7360+, and around Ross Mountain.

The clouds added an aesthetic element to the adventure, as well as a little uncertainty. They accentuated and embellished the terrain, while threatening to make the conditions wet, cold and disorienting. Being familiar with the route helped me to enjoy the experience more than the concerns.

After navigating the false summits along the final stretch of ridge, I finally reached Ross. And, of course, it was in the clouds. That was the tradeoff for the spectacular views of the clouds along the ridge.

I didn’t spend much time on the summit. The more time I could spend out of the clouds, the more enjoyable would be the 2200’+ climb back to Baden-Powell.

It took a little over two hours for the clouds to chase me back up the ridge, but only an hour to run the four miles down from Baden-Powell to the foggy trailhead.

Windy Windy Gap and Sunny South Mt. Hawkins

As shown on fire maps, Windy Gap was not burned in the 2020 Bobcat Fire.

There was hardly any wind on the drive out to Azusa, and I wondered if the offshore wind event forecast to peak this morning was going to happen. But after winding up Highway 39 to the Windy Gap Trailhead, all doubts vanished. The wind was blowing in powerful gusts that shook the car and my enthusiasm.

Not only was it windy, it was cold. I briefly debated going down to warmer climes — temps were forecast to be in the 80s and 90s in the valleys — but decided to at least run up to Windy Gap and see what it was like there.

As is often the case, once I got moving, it wasn’t too bad on the Windy Gap Trail. It was very windy in some spots and nearly calm in others – just what you would expect on the lee size of a mountain ridge. One thing was consistent — there was almost no sunlight on the trail.

I’d been curious to see how the run/hike to Windy Gap (7588′) from the Windy Gap Trailhead (5836′) in the Crystal Lake Recreation Area compared to starting at the Islip Saddle Trailhead (6650′) on Hwy 2. It turns out the distance using either approach is the same — a little over 2.5 miles. But, the Windy Gap Trailhead is lower, so starting there adds a little over 800′ of gain. Today, that extra gain was helping to keep me warm.

As I worked up the last long switchback I could see and hear the trees on the crest being buffeted by the wind. Reaching Windy Gap I’d was relieved to see that it looked the same as it always has. As shown on fire maps, Windy Gap was not burned in the Bobcat Fire.

That relief was short-lived as I was just about knocked down by a gust of wind. I’ve passed by Windy Gap many times, and the wind this morning was the strongest I’ve experienced there.

Later I found that several gusts over 50 mph were recorded at Chilao that morning. Because of terrain effects, I would not be surprised if the gusts at Windy Gap were 60 mph or more. The gusts were “stop you in your tracks, blow you over” strong. And it was cold. The temperature sensor on my pack read 34°F.

Out of curiosity, I ran a short distance along the PCT to see if conditions improved. That was a bad idea. I turned around and got the heck off the crest.

Running back down the Windy Gap Trail, I wasn’t ready to call it a day. It occurred to me that I could run down to the South Mt. Hawkins Trail — the old South Hawkins Lookout service road — and then run up to South Mt. Hawkins. Maybe the old road would be more wind-protected than the Windy Gap Trail.

And maybe not! Looking at the topography, I could not figure out why the wind on some sections of the South Mt. Hawkins road was so strong. Some gusts were as strong as at Windy Gap. The noise from the wind in the trees was deafening, and amplified my concern about falling trees and flying debris. I did not want to have a “Weather Channel” moment.

Although the wind was strong, the sun was now higher, and some sections of the road were warmed by the sun. This made a big difference. As I wound into and out of the side canyons, the temperature varied from the high 30s to the low 50s. In two places there were small, dirty patches of icy snow.

The South Mt. Hawkins Lookout was destroyed in the 2002 Curve Fire. Many, many thousands of trees were killed in that fire and the process of (natural) reforestation can be seen on the slopes above the road.

Ironically, the wind and temperature were relatively moderate on the summit of South Mt. Hawkins! After taking a few photos, I descended the “Ridge Trail” to the South Mt. Hawkins trail/road, and made my way back to the Windy Gap Trail and the trailhead.
