Goldfields are tiny wildflowers, but their bright yellow color more than makes up for their diminutive size.
Goldfields bloomed a little early on Lasky Mesa this year. Depending on the conditions, they usually begin to bloom in mid-February. Because of this rain year’s wet December and dry January-February, the goldfields began to bloom a little early — around February 4. The flowers aren’t as numerous as last year, but there are still a few small patches of goldfields to be seen.
Usually, about the same time goldfields begin to bloom, valley oaks are starting to sprout new, bright green leaves. This Winter, the foliage on valley oaks at Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch) began to turn brown in mid-December and I saw the first new leaves begin to sprout at the end of February. This sprawling valley oak is in East Las Virgenes Canyon.
The view above is from the John’s Meadow Trail, a circuitous trail that winds its way through a less-traveled part of the San Gorgonio Wilderness.
The prominent canyon in the photo is home to Forsee Creek. During the last ice age, it held one of San Gorgonio’s small glaciers. I’d just crossed the Forsee Creek a few minutes before, and in a few hours would run past its source high on the crest — Trail Fork Springs.
The peak at the head of the canyon is East San Bernardino Peak (10,691′). Its summit marks the crest of the divide and the location of the San Bernardino Peak Divide Trail. That’s where I was headed, but the path would be anything but direct.
From the Forsee Creek crossing at 7270′, the John’s Meadow Trail climbs about 1000′ in 2.3 miles to join the Divide Trail at “wheelbarrow junction,” about 5 miles west of East San Bernardino Peak. From that point I worked up the popular and scenic Divide Trail, visiting Limber Pine Bench (9330′), Washington Monument (10,290′), and San Bernardino Peak (10,649′) along the way to East San Bernardino Peak.
Using this roundabout — but very scenic — route, it took me about the same time to reach San Bernardino Peak from the Forsee Creek Trailhead as it does to do San Gorgonio Mountain from the South Fork Trailhead. From San Bernardino Peak it’s a little less than a mile to East San Bernardino Peak and from there only about 0.75 mile to the lateral to Trail Fork Springs.
From the westernmost Trail Fork Springs junction with the Divide Trail the theme was downhill, downhill, and more downhill — about 3800′ of downhill over 6.7 miles.
The running on the Forsee Creek Trail was generally very good. I was glad I did the loop counterclockwise. The John’s Meadow Trail and its extension are enjoyably primitive — they appear to be “use” trails that have evolved over time. On the other hand, the Forsee Creek Trail is a constructed trail. It was designed as a pack trail, so is generally well-behaved. Great for going down, but a long haul up with a heavy pack!
Note: Water is generally more reliable and accessible on the John’s Meadow Trail than on the Forsee Creek Trail. Trail Fork Springs and Jackstraw Springs are seasonal water sources that may not have water. Check with the Mill Creek Ranger Station for the current conditions and more info.
One day while running at Ahmanson Ranch, I was admiring the stately limbs of a large valley oak, and noticed that along the margin of the canopy were several sapling oaks. As I continued my run, I found that only a few other valley oaks hosted a brood of young trees.
That oaks would sprout on the margin of the canopy made sense. There is an abundance of acorns at the ends of the limbs. It is also where water drips from the oak’s leaves on foggy days or when there is light rain or drizzle. The mix of sun and shade on the edge of the canopy is the perfect place for a young oak to thrive.
The surprise came when I took a closer look at the young trees. Most were valley oaks — the same as the shepherding tree — but in some cases the young trees were coast live oaks! And sometimes there was no obvious parent coast live oak nearby.
Of course, there are plenty of coast live oaks at Ahmanson and several ways for their acorns to find their way under a valley oak. Birds and squirrels love to stash acorns, and gravity is good at moving round things downhill.
Time is at a different scale for a tree. In my mind’s eye I accelerated time and watched as the young oaks surrounding a guardian oak grew in stature. Fire sweeps through the frame on several occasions. During one fire the old brood tree collapses and in another fire, the collapsed tree disappears from the frame. Of the young oaks that have survived, one dominates, spreading its limbs and growing large and robust. Along the margins of its canopy, I can see several sapling oaks…
Note: The young oaks in the title photo are an older brood that survived the Woolsey Fire, but many younger sapling oaks were killed. Introduced grasses, black mustard, and other introduced plants produce higher fuel loads than native equivalents and increase fire mortality.
Parked in a turnout on Mulholland Hwy, I finished putting on sunscreen and then pushed the Start/Stop button on my watch to dial in the GPS and pair my HRM. Outside, it was a chilly 43 degrees. Sunrise was nearing and the strengthening March sun was forecast to push temps well into the 70s.
In the aftermath of Woolsey Fire, I’d returned to Malibu Creek State Park to see the wildflowers; gauge the response of the creek to heavy Winter rains; check on the health of the redwoods along the Forest Trail, and assess the ongoing recovery of the burned chaparral.
Today’s run of the Bulldog Loop would be a follow-up to two runs in the park in December 2018, which found a fire-ravaged landscape just beginning the long process of recovery.
Many of the live oaks and valley oaks in the Woolsey Fire burn area have withered, brown, scorched leaves. As bad as they look, most of these trees will replace their foliage and recover.
Today I was excited to see foliage replacement occurring on several live oaks in the northeastern area of the fire. This also happened about a month after the 2005 Topanga Fire.
Back in 2005, valley oaks also started replacing their leaves about the same time as the live oaks. That might not happen this time. Valley oaks are deciduous and the Woolsey Fire occurred later in the Fall than the Topanga Fire. Now is about the time valley oaks would be losing their leaves. That may affect the timing of their foliage replacement. We’ll see!
I’d done a long run the day before in Pt. Mugu State Park, so the plan for this morning was to do a short run and check out the Woolsey Fire impacts between Century Lake and the MAS*H site in Malibu Creek State Park.
In addition to checking the condition of the coast live oaks and other native trees, I was curious to see how the coast redwoods along the Forest Trail had fared. These trees were planted nearly a century ago and in recent years have struggled with the drought. Had they survived the fire?
It had been about a year since I had checked on the redwoods. The good news is that a few of them still appear to be viable. The bottom limbs on some of the trees were scorched, but I think they will be OK. Of the 16 or so redwoods, about five have died, about five are in poor shape, and five or six appear to be OK. There is one young naturally occurring tree that was severely scorched and may not survive. We’ll just have to see.
While there was some damage to the MAS*H site, the picnic tables, ambulance, and signpost made it through the fire. Some repairs will be necessary.
I was supposed to turn around at the MAS*H site, but you know how that goes. I wanted to see “just a little” of the Bulldog climb… and a little more… and a little more. I finally ran out of time about 2.5 miles up Bulldog Mtwy and headed back.
Even when you expect it, it is sobering to see areas of high soil burn severity. Thirty-six years of robust chaparral growth were just… gone. Also startling were the stream flows and debris flows that resulted from “only” about 1.5 – 2.0 inches of rainfall in early December. An atmospheric river event of the magnitude that caused the Malibu Creek flooding in February 2017 would be catastrophic.
A lot of work had been done on Bulldog Mtwy. It had been repaired and graded. Where there was still brush and trees along the road the branches had been trimmed!
