The photograph Moon and Sycamores was taken at dawn, near Malibu Canyon and Piuma Road, at the start of this morning’s Bulldog Loop trail run in Malibu Creek State Park.
According to the Tempe sensor on my pack, the temperature ranged from a chilly 32° F along Malibu Creek to around 65° F on the crest. It was a near perfect morning to be outdoors.
As of March 1, Downtown Los Angeles had recorded only 1.99 inches rain over the past eight months. Most of that was recorded in one storm in early January. It was the second driest July 1 – February 28 on record.
Following the January storm, temperatures warmed up and stayed relatively warm for much of the next 30 days. In the West San Fernando Valley the high temperature hit 89 °F at Pierce College on February 4, and was over 80 °F for 12 consecutive days. Some plants (and some rattlesnakes) responded as if it was Spring.
In mid February Winter returned, with cool daytime temperatures and cold nights. There were Frost and Freeze Warnings on several nights.
In March the ridiculously resilient ridge of high pressure over the West Coast finally relented, resulting in above normal rainfall. It took awhile, but the March rain and April sun eventually produced an assortment of wildflowers.
The high point of the 14+ mile Bulldog Loop in Malibu Creek State Park is near the center of the skyline in the photo above. The Bulldog fire road can be seen cutting across the peaks on the right. Bulldog tops out at the Castro Peak fire road, which is the fire road leading up from the Corral Canyon Road parking area. Castro Peak (privately owned) is the peak on the left with the antennae.
From Crags Road to Castro Peak fire road, the Bulldog fire road gains about 1727 feet in 3.4 miles. The steepest mile starts at mile 2.0 of the climb and gains about 732 feet.
Today I was running the loop clockwise, so got to run down Bulldog for a change!
My plan had been to check on the MCSP redwoods and then do the Phantom Loop. Running along Crags Road west of Century Lake I started noticing flood debris along the trail, but it wasn’t until I reached the bridge across Malibu Creek that the magnitude of the flooding became evident. Most of the bridge’s wooden railings had been swept away and debris hung in the trees 10-15 feet above the creek.
The flooding resulted from heavy rainfall associated with an atmospheric river that hit the area on February 17. Between 4:00 a.m. and midnight the Remote Automated Weather Station near Malibu Canyon Road and Piuma Road recorded 4.45 inches of rain. Runoff was increased by the soil being nearly saturated from the above average rainfall we’ve experienced this rain season.
Many streams in the area experienced high flows on February 17. According to provisional USGS data Sespe Creek near Fillmore peaked at 34,000 cfs at 7:45 p.m.; the Ventura River near Ventura peaked at 20,400 cfs at 5:45 p.m. and the Los Angeles River at Sepulveda Dam peaked at 16,700 cfs at 4:30 p.m.
Eventually I returned to the Forest Trail and checked on the redwoods. My impression is that the trees in trouble have continued to degrade and the trees in better condition are holding their own. I will be curious to see how much new foliage there is later in the growing season.
I never did make it to the Phantom Trail but did have a nice run over to the Tapia Spur Trail.
