Canyon View

Cheeseboro Ridge Trail, Cheeseboro Canyon and Sheep Corral Trail

Cheeseboro Canyon is the prominent canyon on the left of the photo. The dirt road is the Cheeseboro Ridge Trail — a power line service road. The Sheep Corral Trail follows the flat-ish terrain in the little valley. It links the Cheeseboro Ridge Trail to the top of the Cheeseboro Canyon Trail about a quarter-mile to the west (right) at Shepherds’ Flat.

There are innumerable trail runs, hikes and rides that pass through here. Here’s a NPS map of the Cheeseboro/Palo Comado area trails (PDF). On this cool, mid-January day I was doing the Upper Las Virgenes Canyon – Cheeseboro Ridge Loop.

Should Los Angeles Have Had More El Nino Rain?

Cirrus clouds

Originally posted January 7, 2016 and rewritten to reflect the current rainfall totals for Downtown Los Angeles.

Based on 1981-2010 climate normals Downtown Los Angeles (USC) receives, on average, 1.04 inches of rain in November, 2.33 inches of rain in December, and 3. 12 inches in January. This past November Los Angeles recorded only 0.01 inch of rain, and in December only 0.57 inch. January rainfall was a few hundredths above normal at 3.17 inches.

The 2015-16 El Nino is one of the three strongest El Ninos in the past 65 years; the other two were 1982-83 and 1997-98. How does the amount of rain we’ve had so far this rainfall year compare to the other two? Is this El Nino failing to produce the expected amount of rainfall in Los Angeles?

On January 7, when this post  was originally written, the rain year totals were in the same ballpark for the date as during the 1982-83 and 1997-98 El Ninos. That is no longer the case, and Los Angeles rainfall totals are falling far behind those other big El Ninos.

As of January 31 Downtown Los Angeles (USC) has recorded only 6.97 inches of rain for this rain year, which is 0.47 inch below normal. At this point during the 1982-83 El Nino Los Angeles had already recorded 12.98 inches of rain, and in the 1997-98 El Nino 9.15 inches.

The good news is that the Sierra snowpack is above average. That helps with the water supply, but not so much with naturally-occurring local groundwater and other drought impacts in Southern California. It does help that the Los Angeles rain year total is nearly normal, but I’m still waiting to see running water in upper Las Virgenes Creek.

Remarkably, as of this morning, the medium range models are forecasting dry weather to predominate over the next 10 days or so and both the GFS and ECMWF show a mega-ridge of high pressure developing over the West Coast this weekend.  We’ll see!

You Can’t See Far in a Cloud

Clouds along the crest of the Santa Monica Mountains near Sandstone Peak

For the most part the upper layer of clouds had been above Boney Mountain. Thin wisps of cloud had clung to the ridges in a couple of places, but the ceiling looked like it was going to remain above the peak.

But then something unusual happened. A lower deck of clouds formed in the Conejo Valley, and then expanded upward, enveloping me as I worked up Boney’s Western Ridge. It wasn’t a whiteout, but in places the visibility was reduced to about twenty feet.

Fog changes the mood and character of a place, particularly a place where airy views and an expansive mindset are the norm. Thoughts turn inward and perceptions more narrowly focused. The big picture becomes entirely virtual.

Earlier in the week the area had been drenched by more than two inches of rain. It had been damp overnight and water filled the profusion of irregular pockets covering the volcanic rock. The rock was plastered with a patchwork of bright green moss and gray-green lichen. Saturated with water, the moss was slippery as ice. I climbed with extra care, especially on the steeper sections.

Where soil collected on tiered steps, obovate leaves of shooting-star and other annuals sprouted, presaging a show of the purple and yellow wildflowers. Chalk liveforever relished the moisture, its drought-scarred leaves rehydrating and recovering.

Higher on the ridge the intricate green foliage of red shanks, still recovering from the 2013 Springs Fire, was heavily-beaded with water. Brushing against it was like being sprayed with ice-cold water.

I remained immersed in cloud all the way up the Western Ridge, past Tri Peaks and over to Sandstone Peak, and didn’t climb above them until near the summit of Sandstone Peak.

A few photos from the climb and run are below. Click an image for more info and to display the image full-size.
