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.
The title photo of silhouetted mountain bikers is from this afternoon’s run at Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch). The image is an example of a “silhouette illusion.” Are the riders going toward or away from the camera?
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.
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.
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.
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.
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.
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.

After so many years of doing the Angeles National Forest Trail Race, I’m not sure I even had a choice. At about 7:00 a.m. on Saturday, July 11, 2020, I found myself running down Mt. Wilson Road.
It was odd not to be surrounded by runners. Gary Hilliard had not done his one-of-a-kind pre-race briefing. There had been no hugs or handshakes at the start of the run. No runners commented on the temperature or talked about past or future races. Thanks to COVID-19, the 2020 ANFTR race had been canceled.
But the mountains and trails were still there, and by running the 25K course, I could get a good idea of what the 2020 race might have been like.
I was not racing the course. The forecast was — of course — for a hot day. And in these covid times, I was running solo. I was out to enjoy “being there” — seeing what I could see, learning what I could learn.
The single-track trail leads up to the Mt. Disappointment service road. The high point of the 60K, 50K and 25K courses — about 5780′ — is along this short stretch of road. For the 25K course it’s (almost) all downhill from here to West Fork. A winding, and usually dusty, single-track trail turns off the service road and leads down through scrub oaks to Mt. Wilson Road, just above Red Box.
The time of day when you do the 5+ mile segment from Red Box to West Fork makes a huge difference. On hot race days, such as in 2012, 2017 and 2018, the road bakes and in-the-sun temps can reach well over 100 degrees. (This isn’t the only part of the 50K/60K course that can be hot!)
Because I was running the 25K course, I was on Red Box road relatively early. It was probably in the 90s in the direct sun, but there were still some cool stretches of shade. In years with average or above-average rainfall, there are usually a few little stream crossings where capfuls of water can be dumped on your head. They were flowing today. Usually at West Fork there is a hose/shower setup to use for cooling.
There was a collapsed sycamore on the trail near the spring, but it didn’t look like it was going to be much of a problem. On the run down to West Fork, I’d noticed an increasing number of trees on the road. About a mile from West Fork, a large oak had fallen down a road-cut, blocking the road and bringing with it a pile of debris.
Leaving West Fork on the Gabrielino Trail, I worked around the fallen sycamore and then continued up the trail. Within yards there was another fallen tree, then another, and another. The number of trees down on the trail was remarkable. Part of the reason is that the Forest Service isn’t currently allowing volunteer groups to do trail maintenance. I’m sure ANFTR R.D. / AC100 Trail Boss Gary Hilliard is going crazy not being able to work on the trails.
But I think there’s more to it than trail maintenance. There are far more trees down on the trail than I’ve seen in other years. The area is covered in scrub oaks and bay trees that were killed by the Station Fire. I suspect the same storms that broke and toppled trees in the San Gabriels high country over the Winter, toppled dead trees here as well.
It became a mantra — over, under, around or through? Over, under, around or through? Tree after tree. It was warming up, and the extra work of battling the trees added to the effort. On the Gabrielino segment of the route, trail users had trimmed some small limbs from a few of the trees, and that helped.
I thought that once I got out of the scrub oaks and into the forest proper, there wouldn’t be so many trees on the trail. That was mostly true, but there were still several tree challenges higher on the Kenyon Devore Trail. One large log was perched across the trail at the top of a steep gully. I didn’t want to slip and started to use the log for hand-holds. Bad idea! Who knew how little force would be required to dislodge the tree.
Eventually, I reached a point on the trail where I could just hike and didn’t have to climb over, under, around or through anything. What a relief!
It’s difficult to estimate just how many trees were down on the trail. Fifty? Sixty? I have no idea. There were many small trees I didn’t even think about, and there were multiple trees down in some spots. However many there are, if another Winter passes before the trails can be maintained, it will require a massive effort to get them cleared.
Based on the temperatures recorded at the Clear Creek RAWS, this would have been the #3 or #4 hottest of the ANF Trail Races. Compared to the other hot races, temps were a few degrees cooler early, but reached similar temperatures by mid-afternoon. The Clear Creek RAWS recorded average hourly temperatures as high as 96°F and average hourly fuel temps as high as 121°F.
