Musch Meadow Frost

Frost along the Backbone Trail at Musch Meadow

As I approached Musch Camp, a scrub jay flew from a trailside faucet and into a nearby eucalyptus. There had been a little rain the day before, but the birds at the closed camp were still thirsty. Less than a quarter-inch of rain had fallen, and nearby creeks were still dry.

I was doing a run from the “Top of Reseda,” and on a warmer day would have topped off my water bottle at the camp. I stopped at the faucet and briefly turned on the spigot. Maybe that would make it easier for the jay.

Leaving the camp behind, I continued south on the Backbone Trail, across frost-covered Musch Meadow. Early morning sun had just reached the meadow, and water vapor from the melting frost steamed in the cold air.

In another mile I reached the Trippet Ranch trailhead, and then begin the six mile run back to the Valley. At several points on the run there had been wintry views of the local mountains. On the way back the best view of the snowy mountains was from the Hub, where Mt. Baldy could be seen gleaming white in the morning sun.

A Dry and Dusty Start to the Los Angeles Rain Year

Except for a teaser storm system in early November that brought a smattering of rain to the metro area and some snow to the mountains, the Los Angeles rain year is off to a parched start.

As of December 1, Downtown Los Angeles (USC) has recorded only 0.11 inch of rain since July 1. Along with 1995, this is the 7th driest start to the rain year over the 144 years weather records have been kept in L.A.

Update December 29, 2020. In the first significant storm of the rain year, Downtown Los Angeles recorded 1.82 inch of rain, bringing the rainfall total up to 1.95 inches. The storm total was more than generally forecast, but L.A. is still about 2 inches below normal for the date. The rain does move 2020 out of contention for the driest first six months of the rain year.

Update December 20, 2020. The period July 1 – December 20, 2020 is the driest on record (for that date range) for Los Angeles. As of December 20, the rainfall total for Downtown Los Angeles (USC) remains at 0.11 inch.

While “past performance may not be indicative of future results,” I was curious to see if, historically, a dry start to the rain year has generally resulted in below average annual rainfall.

There have been 16 years in which Los Angeles precipitation was 0.25 inch or less for the period July 1 to December 1. Rain year precipitation (July 1 – June 30) for those years varied from a low of 4.79 inches in 2017, to a high of 23.43 inches in 1937. Overall, these years averaged 11.34 inches of rain annually, which is 3.66 inches below the current normal of 14.93 inches.

Whether or not annual rainfall this rain year is below normal we’ll have to see. An important consideration is that La Nina conditions are present in the equatorial Pacific. This doesn’t necessarily mean less rainfall in the Los Angeles area, but taking into account a number of factors, the Climate Prediction Center is projecting below average precipitation this Winter in Southern California.

A Windy Run, Walk, Ride, for Wildlife Research

The Overlook Fire Road in Pt. Mugu State Park was nearly empty. I’d seen only two hikers between the top of the Fireline Trail and the top of the Wood Canyon Vista Trail. Maybe it was the wind. There had been 20-25 mph wind gusts much of the morning. Along the ridgelines, the gusts were even stronger.

Run, Walk, Ride 2020

I’d picked Pt. Mugu State Park to do a run in support of the Santa Monica Mountains Fund’s Run, Walk, Ride, for Wildlife Research. Many mountain lions have included Pt. Mugu State Park in their home range, including P-1, the patriarch of the mountain lions in the Santa Monica Mountains study.

According to the NPS website, the Santa Monica Mountains National Recreation Area is the world’s largest urban national park. Wildlife in the Park is affected by issues resulting from the proximity of urban and wild areas. Among the problems are poisoning from anticoagulant rodenticides, limited genetic diversity, and vehicular deaths. Only by studying Park wildlife can we better understand and manage these and other issues.

Because water is usually available at several spots in Sycamore Canyon, it’s a great place to do a self-supported ultra-length trail run.

So far, today’s run had taken me from Wendy Drive in Newbury Park to Serrano Valley via the Old Boney Trail. I’d circled past the old ranch in Serrano Valley and then descended the Serrano Canyon Trail to Sycamore Canyon. A short jog south in Sycamore Canyon put me at the bottom of the Fireline Trail, which I’d followed up to the Overlook fire road.

Next up was a scenic loop in La Jolla Valley. After that, I would work my way back to the Upper Sycamore Trail via Sycamore Canyon. From there, it would only be a few miles back to the Wendy Drive Trailhead.

The Santa Mountain Mountains Trails Council has been hard at work. Even though they can’t currently accept volunteer assistance, it looked like the Old Boney, Serrano Canyon, and Upper Sycamore Trails had been recently maintained.

Bulldog Loop Plus the Phantom Loop

The Bulldog Loop, without any extras, is a little over 14 miles long, with an elevation gain of about 2700′.

While doing the Phantom Loop last week, I was reminded that a good way to extend the Bulldog Loop is to combine it with the Phantom Loop. This produces a run of about 19 miles, with an elevation gain of around 3650′.

This weekend I was looking to do something a little longer. With the National Forests in Southern California still closed, the usual high country options weren’t available. The temperature forecast looked warm, but not crazy hot, so it was a good day to do this run.

The Cistern/Phantom Trailhead on Mulholland Highway is a convenient place to start and end the loop. Later in the run, water is usually available from a faucet and fountains adjacent to the restrooms at the main MCSP parking lot. If doing the loop counterclockwise from the Cistern Trailhead, the restrooms and water are about 14 miles into the run.

The main attraction is still the Bulldog climb. From Crags Road to Castro Mtwy, the Bulldog Mtwy gains about 1730′ over about 3.4 miles. From the MCSP parking lot to the high point on the Phantom Trail, the route gains a bit more than 1000′ over 4.7 miles.

Here’s an interactive view of the merged 19 mile loop. A longer variation continues on the Grasslands Trail to De Anza Park and returns to Liberty Canyon on the Talepop Trail.

Redwoods, Raptors, and the Phantom Loop

It was a chilly 45°F as I crossed algae-covered Malibu Creek on a foot-worn log. Following a brutally hot Summer with temps in the West San Fernando Valley reaching 121°F, the chill of the cold air felt especially good.

The plan was to do the Phantom Loop, but first, I was going to run over to the Forest Trail. The side trip was not only to check on the coast redwoods along the trail but to enjoy the calm beauty of the area. To say 2020 has been unsettling is like saying a rattlesnake bite is a little annoying — and the year isn’t over yet.

After crossing the creek, I stopped to photograph the redwood near the junction of the Forest Trail and Crags Road. The sun had just risen, and behind the tree, orange-tinted sunlight illuminated the rocky ridge above the M*A*S*H site.

Continuing along the Forest Trail toward Century Lake, I counted four healthy-appearing redwoods and two struggling trees. Redwoods sometimes grow in a group of two or mote trees, and these were counted as a single “tree.” Near the end of the trail is a naturally-germinated redwood that has grown to about 5.5 inches in diameter. Remarkably, this young tree survived the 2011-2015 drought and the 2018 Woolsey Fire, and appears healthy!

I had just finished photographing the young tree when a Cooper’s or Sharp-shinned Hawk flew from a nearby oak and through the trees along the trail. It landed on the limb of an oak ahead of me but was in deep shade. In a much-enlarged image, the bird looks like a Sharp-shinned Hawk, but distinguishing the two species can be challenging.

A few yards down the trail, a much larger raptor — a Red-tailed hawk — was perched at the top of the tallest redwood. The huge bird had its wings pulled back to expose more of its body to the warming sun. It looked like a giant penguin sitting atop a tree. As I approached, it began to preen its feathers, comfortable with its lofty position.

With a sigh, I left the Forest Trail behind and returned to Malibu Creek. This time I crossed the creek on a plank near the washed-out bridge. This was a more direct route than the fallen tree upstream but only worked because the creek was low. At the crossing, a passing runner asked if he was on the Bulldog Loop. I assured him he was and was a little envious that he was getting to experience that excellent run for the first time.

As usual, Crags Road and the High Road were busy thoroughfares. The easy running under the sprawling coast live oaks was pleasant, and the morning view of Malibu Creek and Goat Buttes outstanding.

In a few minutes, I’d reached Mulholland Highway and then followed the Grasslands Trail to the Liberty Canyon Trail. From Liberty Canyon, the Phantom Trail gains about 750′ in elevation over about 1.5 miles to a high point and ridgeline with excellent views of Saddleback Peak, Las Virgenes Canyon, Brents Mountain, Goat Buttes, Castro Peak, Ladyface, and Boney Mountain.

The air quality this morning hadn’t been too bad. From up on the ridge, I could see there was far less smoke to the west of Las Virgenes Canyon than to the east. Yesterday, I’d done a run in the eastern Santa Monica Mountains and had to cut the run short because of smoke. That wasn’t a problem today, and the run had been a good one.
