Upper Las Virgenes Canyon: Humboldt Lily Run

Humboldt lily in Upper Las Virgenes Canyon

Was looking to get in a short run this morning and decided to check if any Humboldt lilies were blooming in Upper Las Virgenes Canyon.

The last time I’d seen Humboldt lilies bloom here was June 2006, following an unusually wet Spring and a two year period in which Downtown Los Angeles recorded 50+ inches of rain. 

This Spring some months were wet and some months were dry, but December 2010 was the wettest in Los Angeles in 121 years. Add to the mix that the last two water years Los Angeles recorded above average rainfall, and it seemed there was a pretty good chance the Upper Las Virgenes Canyon lilies would be in bloom.

I’d seen lily stalks in other areas in recent weeks, and some blooming Humboldt lilies in the San Gabriel Mountains, but when I checked Upper Las Virgenes Canyon in early May, there had been none. But today there was — right in the middle of thorny patch of blackberry bushes.

Also blooming in the canyon were California wild rose and the non-native plant moth mullein — so named because of the similarity of the flower’s anthers to the fuzzy appearing antennae of a moth.

Atmospheric Dynamics

Complex of mountain wave clouds to the north-northeast of Mt. Pinos

These unusual clouds are a complex of lenticular clouds to the north-northeast of Mt. Pinos, photographed this morning from near Mt. Abel. They were produced by strong south-southwesterly winds blowing across the east-west oriented Emigdio and Tehachapi mountain ranges, north of Los Angeles. Here’s another view of these clouds from near the summit of Mt. Pinos.



The winds were associated with the circulation of an unseasonably strong low pressure system off the California coast. The storm system has resulted in measurable rain as far south as Santa Barbara County, and new rainfall records for the date were set in San Francisco, Paso Robles and Santa Maria.



The photographs were taken during a blustery out and back trail run from Mt. Pinos to Mt. Abel on the Vincent Tumamait Trail in the Chumash Wilderness. At the start of the run, the temperature at the Chula Vista trailhead (8400′) on Mt. Pinos was a chilly 39°F. In exposed areas the wind speed was 20-25 mph with gusts to around 50 mph.

Other than the potential for deadfall, the wind wasn’t too bad in the trees. The Vincent Tumamait Trail was in the best condition I’ve seen in years.

Update June 6, 2011. The low that was off the Central California coast Saturday and most of Sunday and an associated cold front set a new rainfall record for June 5 at Santa Barbara Airport, and produced a few sprinkles and showers in the Los Angeles area.

View west across Topanga Canyon to Saddle Peak from viewpoint near the Temescal Ridge Trail.

Southern California doesn’t get much rain in May. On any given day in the middle of May the chance of measurable rain in Los Angeles is around 4 in 100. Overnight we’d beat those odds, and this morning the weather looked more like March than May.

The view above, across Topanga Canyon to Saddle Peak, is from a popular viewpoint off the Temescal Ridge Trail (Fire Road #30), about 4 miles into the Trailer Canyon – Trippet Ranch Loop. This 17 mile route is one of several excellent trail runs that start at Marvin Braude Mulholland Gateway Park in the San Fernando Valley. It crosses the Santa Monica Mountains on the Temescal Ridge and Trailer Canyon fire roads, dropping down to Pacific Palisades, and then returns by way of Santa Ynez Canyon, Trippet Ranch, and the Musch & Garapito Trails.

Mt. Waterman Pines & Clouds

Last Sunday started with light rain in western Los Angeles County, and on the drive to the San Gabriel Mountains, I wondered if the Three Points trailhead would be above the mile deep cloud layer. It was, but barely so, and at the start of the run a couple of scuddy clouds hung over the parking lot.



These were soon left behind, and while the lowlands dealt with damp, dreary weather, my Easter morning run on the PCT continued toward Cloudburst Summit under a bright sun and mostly cloudless skies.

I encountered my first patch of snow a little past Camp Glenwood, on a shaded north-facing slope at about 6300′, nearly three miles into the run. With the above average snowpack, it would have been a surprise not to find some patchy lower elevation snow. Much more snow could be seen on the higher elevation slopes, and the big question was: how much snow would there be on the Mt. Waterman trail?

From Cloudburst Summit I continued eastward on the PCT to Cooper Canyon — one of the most idyllic places in the San Gabriel Mountains. Snowmelt had increased the streamflow, and to start the climb to Buckhorn, two creek crossings were required. It was cool enough that if I could avoid it, I didn’t want to soak my shoes. On the other hand I would rather have wet shoes, than fall bodily into a creek trying to keep them dry. A makeshift trekking pole helped prevent either scenario. Cooper Canyon Falls was spectacular.



On a Summer day this route can be quite warm, and I usually top off my Camelbak at Buckhorn Campground. Good thing it was a cool day — Buckhorn Campground was closed and the water in the campground was turned off. It looked like the Forest Service was doing a major revamp of the campground.

From the campground I still couldn’t tell if the Mt. Waterman trail was going to go. There was a lot of snow on the north-facing slopes, but I was betting it wasn’t going to be as choked with snow as it looked. Worst case, I could turn around, so I decided to continue until there was some reason not to.

There was some snow, and at one point I left the trail to avoid a particularly steep snow slope. About a mile from Hwy 2, the trail worked up onto a broad east-facing ridge, and from that point the trail was mostly free of snow.



No sooner had the snow issue been resolved, when clouds began to spill over the ridges and increase overhead. I knew — or at least thought I knew — that other than decreasing the visibility and temperature, these clouds shouldn’t be a problem. Even so, I was very glad to know the terrain and route well, and have some additional gear in my pack.

The title photograph is from the upper section of the Mt. Waterman trail. The clouds are in the deep canyon between east ridge of Waterman Mountain (8038′) and Twin Peaks (7761′).

Wow, What a Great Day for a Trail Run!

Ridge near summit of Tri Peaks

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.

Even in Southern California, Spring can be a fitful beast. This afternoon the temperature was in the low 50s, and the wind was blowing hard enough it was difficult to take a photograph. Just one week ago it had been a stifling 95 degrees — a temperature swing of more than 40 degrees.
