Three Points Loop Plus Mt. Waterman

If you spend much time in the mountains, sooner or later you’re going to get caught in a severe thunderstorm. I don’t mean you’re going to hear a little thunder and get a little wet. I mean you’re going to find yourself in the middle of a heart-pounding, ear-splitting, ozone-smelling, sense-numbing storm that drenches you through and through and wrings the nerves from your body.

Having been caught in such thunderstorms while climbing in Yosemite, running in the San Gabriels, and running at Mt. Pinos, I do my best to avoid the beasts. Sometimes, it is not an easy thing to do.

Take this weekend for example. I have a 50K race coming up, and in addition to increasing my weekday mileage, I needed to do a Sunday run of about 20-25 miles — preferably in the mountains.

The Sierra was out. A monsoon pattern virtually assured widespread, and possibly severe, thunderstorms. Some forecast models were saying that the focus on Sunday might be the Ventura County mountains, so Mt. Pinos — the site of my most recent thunderstorm adventure — was also out. Both San Gorgonio and San Jacinto had been hit pretty hard on Saturday. That left the San Gabriels, and thunderstorm activity was expected there as well.

The choices were A — get up really early and try to beat the heat and humidity and run local; or B — get up really early and try to get in a mountain run before the weather OD’d…

Running up the Mt. Waterman Trail, one of my ever-optimistic running partners voiced, “Hey, have you heard about the unusual number of lightning deaths recently?” So far it had been a spectacular day. A broken layer of mid-level clouds — remnants of yesterday’s storms — shrouded the sky. By keeping things a little cooler, the clouds had delayed the development of today’s thunderstorms.

We had started at Three Points and run up the Pacific Crest Trail to Cloudburst Summit, then down into Cooper Canyon, where we left the PCT and ascended the Burkhart Trail to Buckhorn Campground. In Cooper Canyon it was obvious there had been heavy rain the day before. Everything was wet, and the willows and lupines along the creek glistened in the muted morning sun. Rivulets of rainwater had incised rills in the trail, pushing pine needles and other debris into patterned waves.

I had already lost the “when it would start raining” bet. I had said 11:00. It was 11:00 now, and still there was very little cloud development. So little in fact, we decided to do a quick side trip to Mt. Waterman (8038′), and jokes were being made about the rain gear in my pack. (My GoLite 3 oz shell made a huge difference in the severe thunderstorm on Mt. Pinos.)

About the time we summited Waterman, things started to cook. The canopy of protective clouds was beginning to thin and dissipate and some cumulus cells were starting to build. I wondered if we would make it back to the car before it dumped.

We didn’t. About 30 minutes later, as we worked down the back side of Mt. Waterman toward the junction with the Twin Peaks trail,  we heard our first grumbling of thunder. In another 30 minutes it started to rain; slowly at first, with large icy drops, then building in intensity, as prescribed in long established thunderstorm protocols. Periodic claps of thunder echoed overhead, and to the north and east.

About 3 or 4 miles of trail remained. Here, the trail winds in and out of side-canyons and for the most part is well below the main ridge, but at some points it is very exposed. Minutes before, we had run past a lightning scarred Jeffrey Pine. Burned and blackened, the bolt had killed the tree. I pick up the pace and try to put the tree out of mind.

It rained hard for a while and then the intensity diminished. The air temperature didn’t drop and the wind wasn’t strong. It seems most of the lightning is cloud-to-cloud and away from us. I’m drenched, but happy — instead of being fierce and frightful, this thunderstorm has been almost puffy-cloud friendly.

In steady rain, we cross Hwy 2 and jog up the trail toward the Three Points parking lot (5920′). As we near our cars, we’re startled by a loud boom of thunder directly over our heads — a not so gentle reminder that thunderstorms come in all sizes, and none come with a guarantee.

Here’s a Google Earth image and Google Earth KMZ file of the loop, including the side trip to the summit of Mt. Waterman.

La Nina Fades as SoCal Rain Season Nears End

It’s been late February since Southern California has had a good soaking rain. As of May 1, the water year rainfall total for Downtown Los Angeles (USC) stands at 13.42 inches. This is 90% of the 1921-2006 average of 14.87 inches. According to the NWS 1921-2006 dataset, the average amount of precipitation in May and June is 0.3 inch and 0.1 inch, respectively. We’ll see if we get that much this year!

La Niña appears to be winding down.  In it’s April 30 ENSO Wrap-Up, the Australian Bureau of Meteorology characterizes Pacific climate patterns as being generally neutral, “with the majority of indicators returning to near-normal levels.” The April 28 ENSO Update from the CPC suggests that La Niña will continue through May-July 2008, but many of the factors discussed indicate general weakening of La Niña. Based on the ONI and MEI, La Nina conditions have existed since about August of 2007.

The photograph of the sun-parched mustard leaf is from a run at Ahmanson Ranch on April 29, 2008.

A Long Run Kind of Day

The beauty and intensity of the day was infectious. Hours before a cold low pressure trough digging down from the Pacific Northwest had carried showers, thunder, hail, and chilly temps into Southern California. Its rainfall had refreshed the greens of the hills, and accentuated the yellows, purples and reds of the wildflowers along the trail. Its blustery winds had cleansed the sky.

A few minutes before I had completed one run, and now was starting another. I wasn’t certain how much farther I would run — I just knew I had to run.

The day had begun with friends on the Secret Trail in Calabasas. We had run up and over the shoulder of Calabasas Peak, and then ascended Saddle Peak via the Stunt High Trail and Backbone Trail. The view from the summit of Saddle Peak had extended beyond Santa Monica Bay and Palos Verdes Peninsula to the South Bay and Saddleback Mountain. New snow glistened on Mt. Baldy, and to the west the rocky summits on Boney Mountain stood in bold relief.

That 14.5 mile run had ended at Tapia Park. Now I was on the Tapia Spur Trail on the first climb of the Bulldog Loop. On the wind sheltered slope the bright yellow blossoms of tree poppy had begun to unfurl, absorbing the warmth of the midday sun. Distant peaks loomed to within an arm’s reach, and my legs seemed to draw energy directly from the trail. It was a long run kind of day.

Notes: The title photograph is of Saddle Peak from the Backbone Trail, in the Santa Monica Mountains, near Los Angeles. Mt. Baldy can be seen in the distance. The combined length of the runs was about 29 miles with an elevation gain of about 5000 ft.

This photograph of downtown Los Angeles and Century City was taken Sunday morning from the Backbone Trail in Topanga State Park while doing the Will Rogers – Temescal Loop from the “end of Reseda” in the San Fernando Valley.

At the time an offshore wind was scouring out low-lying fog trapped in the Los Angeles basin by a low altitude temperature inversion.

Vernal Pool at China Flat

Vernal pool near the sheep corral at China Flat in the Simi Hills.

In normal to wet rain seasons vernal pools can be found throughout the Simi Hills. The pool pictured above is near the sheep corral at China Flat, and another small pond was found nearby, along Albertson Motorway fire road. I’ve also found vernal pools in the Rocky Peak area and near Sage Ranch.

Geologically, the Simi Hills are characterized by the sandstone rocks of the Chatsworth formation. These inclined layers are of varying hardness, and erode at different rates. It’s my guess that water collects in sandy soils between, or at the base of, the more resistant layers.

The photographs of the ponds at China Flat are from Sunday’s Scenic Route to Simi Peak run.
