Valley Oak Sunset

After chugging up the long climb, I pause on the crest of the hill. Open space surrounds me. In a nearby oak, small birds twit and twitter, preparing for the night. In the distance coyotes yip and yell, an announcement on one hilltop, and an answer on another. A cold ribbon of wind brushes against my leg.

I take a deep breath and smile. At sunset the day melds to an end, becoming rich with sights, smells, and sounds. In the moment, senses converge and thoughts coalesce.

There is form in the oak’s twisted limbs. A dove dives from its branches, and I turn for home.

Water Droplets on Coffee Fern

Water droplets on the leaf segments of coffee fern (Pellaea andromedifolia).

More delicate than the finest holiday crystal, the leaf segments of this coffee fern (Pellaea andromedifolia) are covered in tiny spherical water droplets. The largest of these droplets is about the size of the head of a pin, the smallest perhaps the size of a grain of salt.

Initially green, coffee fern turns various shades of red, brown, or purple with age.

Clearing Clouds from Sage Ranch

Clearing clouds, northwest of Los Angeles, following the passage of an upper low storm system that resulted in widespread rainfall in Southern California.

Clearing clouds, northwest of Los Angeles, following the passage of an upper low storm system that resulted in widespread rainfall in Southern California. Several rainfall records for November 26 were broken in Los Angeles County.

Update 12/5/08 P.M. High amplitude flow continues to wreak havoc with forecasts. Our on-again, off-again chance of a shower this weekend might be on again. Original cut-off upper low center is still well offshore, but another low center has developed on the downstream side of high amplitude ridge, and this one is much closer to the Southern California coast. The low appears to be entraining some moisture, and could produce some showers, particularly as the low moves onshore and is absorbed in the main flow. We’ll see!

Update 12/5/08 A.M. No rain is expected in SoCal this weekend… The cut-off upper low set up much further west than suggested by models Tuesday and now is spinning out in the eastern Pacific, nearly halfway to Hawaii. At the moment, it looks like it could be mid-month before our next chance for significant rain.

Update 12/2/08. Computer models have been having a tough time with both the short and medium term forecasts for Southern California. Recent runs have been hinting at the possibility of some rain Saturday or Sunday. This would depend on the strength, position and behavior of an upper low that is forecast to form off the Southern California coast Thursday.

Fossil Trail – Pt. Mugu State Park

Shell impressions on the Fossil Trail in Pt. Mugu State Park.

The Fossil Trail is a steep, approximately mile-long trail in Pt. Mugu State Park that connects the Upper Sycamore Trail, near its junction with Sycamore Canyon Road, to the Old Boney Trail. The most obvious fossils are shell impressions and remnants found in an exposed layer of sandstone about a tenth of a mile below the Old Boney Trail junction. Some of the shell impressions are palm-sized and larger.

The shells appear to be a type of cockle (Anadara devincta) that is an indicator of Miocene-age formations. (See the Oregon Sea Grant publication “Fossils You Can Find on Oregon Beaches.“)  In this case, the fossil exposure appears to be in the Lower Topanga Formation, which is believed to have been formed in the middle to early Miocene, about 20 million years ago.

The shape, thickness and ribbing of this type of shell increases its strength and resistance to crushing — improving the shell’s chances of remaining intact when buried in sediment, and during subsequent geologic processes. This may be one of the reasons it is a prevalent indicator fossil.

Sesnon Fire Recovery – First Growth

Terminal budding in yerba santa 3 weeks after the 2008 Sesnon Fire.

Only three weeks after the area was burned in the 2008 Sesnon Fire, this yerba santa shrub on the Chumash Trail has started the process of foliage replacement. In many areas along the trail, grasses and other annuals (many invasive) were consumed, but adjacent chaparral shrubs were only scorched. Many of these shrubs look like they will be able to recover through budding of existing stems, rather than crown-sprouting.

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.

See the Santa Monica Mountains Trails Council web site for more info.
