What the… Until I saw the water bottle and that the person was talking on a cell phone, I wasn’t sure what I was seeing.
Then there was the rattlesnake — well actually, the two rattlesnakes! Here’s an video snapshot of one of the rattlesnakes. This is an average size Southern Pacific rattlesnake. Because of our cool Spring weather they’ve been slow to appear, but are now out and about.
The Wendy Dr. trailhead in Newbury Park is a gateway to some of the most scenic and spectacular trail runs in the Santa Monica Mountains. Runs, hikes and rides on the extensive and diverse network of trails can range from a few minutes, to many miles and hours.
Today my run was of the “few hours” variety. The weather in Pt. Mugu State Park was perfect for a longer run — partly cloudy, light winds, and the temperatures ranged from the high 40s in the morning to the high 60s midday.
La Nina or El Nino, rain seasons as wet as the 2010-11 season are relatively rare. The wet weather produces a cascade of effects, resulting in conditions that might not be seen again for years. Streams that had not run for years were flowing; numerous wildflowers were blooming; the chaparral and other plant communities, and their inhabitants, were flourishing. I did not want to miss anything.
With that thought in mind, my route took me up and over Boney Mountain and Tri Peaks to the Backbone Trail, and then down the Chamberlain Trail and Old Boney Trail to the Serrano Valley Trail. After running through resplendent Serrano Valley, I continued down Serrano Canyon, crossing the creek 15 times, all the while trying to avoid the lush growth of poison oak along the trail. Even the miles returning up Sycamore Canyon were enjoyable, and involved a few stream crossings. The Upper Sycamore Trail and Danielson Road led back to Satwiwa and the trailhead.
On this particular day it was as fine a trail run as I have done, and probably the most scenic loop I’ve done in the Santa Monica Mountains.
This weekend I decided to give my legs a break and instead of 9 pounds per foot of ski, binding, boot and climbing skin, treated them each to 13 ounces of running shoe. I was thinking about it the other day — skiing up San Jacinto with my tele gear is a little like strapping two 5 lb. bags of sugar to each foot, going up to (on average) 9,500 feet, and then climbing 4,000 or so stairs. I either need to get lighter gear, or go back to using my Europa 77s!
Today’s run was an elongated loop through one of the more isolated and rustic areas of upper Las Virgenes Canyon. From the Las Virgenes trailhead of Upper Las Virgenes Canyon Open Space Preserve the 14.5 mile route followed upper Las Virgenes Canyon and Bell Canyon roads to the overgrown (and easy-to-miss) single track that leads to the west and connects to the Edison powerline service road. This Park Service PDF includes a map of the area, and this interactive Cesium browser View shows a trace of my route.
After climbing up and over a rocky ridge and down to the junction with the Sheep Corral Trail, the service road continues south along Cheeseboro Ridge all the way back to the Las Virgenes Canyon trailhead. With all the rain, and recent warm weather, Spring was happening in a big way in the chaparral. Over the course of the run I photographed nearly 40 species of plants that were in bloom. Here are a few of the wildflowers:
Orographic lift, waves, and turbulence over the San Jacinto Mountain Range
After last Sunday’s record-setting storm in Southern California, and the cool, unsettled weather during the week, we expected snow conditions on Mt. San Jacinto to be even better than on previous trips this March. But snow conditions — especially backcountry snow conditions — aren’t always what you expect. The new snow, maybe a foot of it, was as thick as wet concrete. If we’d had a little kiwi fruit flavoring, it would have been perfect for shave ice.

Even if the snow wasn’t what we had hoped for, the day was extraordinary. Another weak front was moving into Southern California and the strong onshore flow ahead of the front was creating several kinds of interesting mountain weather phenomena — some common and some not so common.
Riding up the tram, we could see plumes of dust blowing across the desert floor east of Banning Pass, and a stack of lenticular clouds hovered over the mountains east of San Gorgonio Mountain. It was breezy at the upper tram station, and from the walkway descending to Long Valley, we could see rimed trees on the southeast side of San Jacinto Peak.

We skied up a beautiful untracked drainage south of the Round Valley trail, and eventually worked our way over to Long Valley Creek and then to Tamarack Valley. We were almost to the top of the steep step above Tamarack Valley, and had paused for a moment to look around. There was a distinctive wave cloud to the southeast, and the lower cloud deck was beginning to engulf Toro Peak (8716′). I turned to continue up the slope, and as I looked up, the first of a series of tumbling and twining filaments of gossamer cloud swept past in the turbulent west-northwest flow (video).
Six months ago, also before the passage of a cold front, I’d seen similar clouds on Boney Mountain, in the Santa Monica Mountains. In that case and here on San Jacinto, a moist layer in a stably stratified westerly flow was being lifted over a mountain range. Depending on whether the flow remained laminar, or became transitional or turbulent; a wave cloud, transient wave cloud, or these turbulent thin sheets of cloud might form. In each case the atmosphere was becoming more moist and the clouds were precursors to the formation of a more widespread and persistent cloud layer.

These vaporous, turbulence-induced clouds bear a striking resemblance to interstellar molecular clouds. Both appear to occur in a high-Reynolds-number regime, and each appears to consist of a cohesive, thin sheet of condensate that can be stretched, sheared, undulated and torn. As in the case of its interstellar counterpart, when viewed edgewise, the clouds look like they are comprised of thin, web-like filaments.
The title photo was taken a little below the summit, after ascending the peak. It’s a view to the south, past Jean Peak (10,670′) and Marion Mountain (10,362′), and shows the terrain induced uplift, waves, and turbulence over the San Jacinto mountain range. The flow is from the right to left.
Weather models were forecasting anywhere from 3.5 to 5.5 inches of rain at Van Nuys for the storm coming in tonight, so this afternoon seemed like a good time to get in a run.
I hadn’t run the Bulldog loop since the Bulldog 50K last August, and needed to catch up on trail conditions, what was blooming, and re-familiarize myself with the difficulties of the Bulldog Climb.
The short version is that the trail along Malibu Creek near the M*A*S*H site wasn’t flooded, but would be in the next 24 hours. Tree poppy, nightshade, hummingbird sage, woolly blue curls, ceanothus and paintbrush were blooming. And the Bulldog Climb was still hard.
It looked and felt like the day before a big storm. Temps were cool, and there was a thick deck of high clouds. Along the crest between the Castro “T” and the Malibu Bowl landslide the wind was blowing in strong gusts from the ESE, and it looked like the clouds might lower, thicken, and unleash a torrent at any time.
Near the end of the run, descending to Tapia Park, I was surprised to see my shadow and some blue sky. That didn’t last for long. By 7:00 the first drops of what would be a record-setting storm started to dot the driveway.

If you were going to pick the most pleasant conditions possible to ski San Jacinto Peak (10,834′), today’s weather would be hard to top. The midday temperature on the summit of the peak was around 40-45 degrees. Winds were light, and it was pull-up-your-sleeves warm — but not broiling — most of the way up the peak.
There was still a lot of untracked snow from last week’s storm, and overall the snow conditions were very good, especially on the steeper, sun warmed slopes southeast of the summit, and in the trees lower on the peak. Here are a few additional photos. Click for a larger image and description:
