Comfortable, cushioned and durable. That's how I would characterize the adidas Response Trail. I've had two pairs of the Response Trail 14s in my shoe rotation since September 2007, and logged around 1000 miles between them. (Your mileage may vary.)

About a month ago I replaced one of the pairs with the adidas Response Trail 15s. I've put 75 miles on the new pair, and other than a change in colors, it seems not much has changed in the shoe. It's still well-cushioned, comfortable and lightweight. The new pair weighed in at 24.7 oz./pair (US 9.5). At $80 or less, the Response Trail 15s are an excellent value.

At the moment, my primary trail running shoes are the Salomon XT Wings (105 miles), Salomon SpeedComp (110 miles), and adidas Response Trail 15s.

Our latest storm added another half inch of rain to our water year total in Los Angeles. This brings the water year rainfall total to 2.85 inches. This is 1.35 inches above normal for the date. As much as a foot of snow was reported in the Antelope Valley and the snow level dropped to near 2000 ft in the foothills and mountains of Ventura and Los Angeles counties.

What's next? Things should stay dry in Southern California until around Monday, when a fast moving front sweeps through the state. Later in the week, sometime around Christmas, the models are suggesting the possibility of a major system impacting California. We'll see!

The photograph of Oat Mountain was taken this morning on an out and back run on Rocky Peak fire road. The highest stretches of the fire road were covered with an icy layer of snow.

Growing in clusters at the top of a bristly, 1-2m, gray-green stem, the flowers of telegraphweed (Heterotheca grandiflora) are a striking yellow.

The plant is native to California. From a Fall run at Sage Ranch.

This grass is not native to California. From a run in October.

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.

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, 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.

We stopped for a few moments at the river crossing, where water stood in pools waiting for Winter rain. Instead, cold air flowed down its course, cool and refreshing. From this point there would be little shade. Rarely cold, the climb out from the West Fork San Gabriel River to Shortcut Saddle is often warm, and sometimes debilitating.

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.
