Facing a Future of Runaway Wildfires in Southern California
It was a sobering sight. I had stopped at a point on Mt. Waterman burned by the Station Fire in 2009 and the Bobcat Fire in 2020.
To the east, smoke from the Bridge Fire filled the canyons and clung to the ridges between Mt. Baldy and the East Fork San Gabriel River. A group of skeletal Jeffrey pines, once full and green, stood starkly in the foreground.
Another devastating fire had stormed through the San Gabriel Mountains, destroying homes and ravaging the forest and all that lives within. Not far away, the Line and Airport Fires were also burning, the extent of the three fires totaling over 117,500 acres.
Conventional methods of land and fire management usually do not prevent the rapid spread of a fire when forest or weather conditions are extreme — and extreme conditions are now the norm.
Incremental changes to long-established policies will not be enough to prevent runaway wildfires. Novel approaches must be considered, researched and evaluated. New tools and technology, including AI, need to be more widely applied. The hesitancy to spend money proactively must be overcome.
Today, it is difficult to do a hike or run of more than a few miles in the foothills or mountains of Southern California without passing through an area that has been burned in the past 25 years. In 50, 100, or 200 years what will the outdoor experience be? Will conifers only exist in widely scattered stands? Will the ecology be forever compromised?
Every effort must be made to mitigate the impacts of runaway wildfires and preserve the nature and ecology of our open space areas and wildlands.

Back to Baden-Powell – August 2024
Above are thumbnails of a few photos from the 16-mile out-and-back trail run to Mt. Baden-Powell from the Islip Saddle Trailhead. Click on an image for a larger photo and more information.
I plucked a currant from the bush and popped it into my mouth. In some years, the red berries are little more than a desiccated bit of pulp. This year’s crop was plump, flavorful, and almost could be described as juicy.
Almost two months had passed since I’d been on the PCT between Islip Saddle and Mt. Baden-Powell. Not a lot changed in the routine of the city in those seven weeks. The street sweeper still came by on Wednesday mornings, the trash was picked up each Friday, and the neighborhood looked pretty much the same as it did at the end of June.
But a lot happens along a mountain trail in seven weeks. The Poodle-dog bush was now wilted and brown. Currants and elderberries had ripened. Rabbitbrush, the messenger of Fall, was blooming, its yellow replacing the pastel purple of Grinnell’s beardtongue. Chinquapin bushes were covered in spiny, green nut burs. Pendulous, resin-coated cones hung from the ends of the long limbs of the sugar pines.
Angeles Crest Highway was still closed between Islip Saddle and Vincent Gap. Gone was the noise of vehicles on the road below, replaced by the sound of the wind in the trees and the occasional outburst of a Clark’s nutcracker.
At the saddle near Mt. Hawkins, I stopped to photograph the stump of the Mt. Hawkins lightning tree. Perhaps weakened by one or more lightning strikes, this Jeffrey pine lost its crown during the Winter of 2019-2020. Now without bark, it’s easy to see that lightning followed the spiral grain of the tree. This tree has a right-hand spiral grain. When viewed from above, it is twisted counterclockwise.
Once again, the visibility from the summit of Mt. Baden-Powell was excellent. San Gorgonio (57 miles) and San Jacinto (72 miles) could be seen far to the east.
It was windy and cool at higher elevation. The National Weather Service’s Wind Chill Temperature formula doesn’t apply to temperatures over 50°F, but with bare arms and legs, it can be surprisingly chilly when there is a strong wind and the temperature is in the 60s. Had I not been pushing the pace, I would have needed to pull the sleeves and shell from my pack.
Here is an interactive, high resolution, 3D terrain view of the out and back from Islip Saddle to Mt. Baden-Powell. An alternative start at the Windy Gap Trailhead in the Crystal Lake Recreation Area is also shown. Starting at this trailhead adds about 800′ of elevation gain. The map can be zoomed, tilted, rotated, and panned using the navigation control on the right. Track and placename locations are approximate and subject to errors. Poor weather and other conditions may make this route unsuitable for this activity.

Out and Back Trail Run from Islip Saddle to Mt. Baden-Powell – July 2024 Update
Update July 22, 2024. The Poodle-dog bush along the PCT near Islip Saddle has been cleared by Gary Hilliard and the AC 100 Trail Team!
When I reached the summit of Mt. Baden-Powell (9,399′), it was empty, save an opportunistic raven who was evaluating the chances that the Larabar I was eating might fall to the ground.
On top, the heat of the strong Summer sun was offset by a cooling breeze. There was still a few thin ribbons of snow in the chutes on Mt. Baldy. With the excellent visibility, San Jacinto Peak could be seen in the notch between Mt. Baldy and Dawson Peak, and San Gorgonio Mountain was sharply visible to the left of Pine Mountain.
Other than a few people at Little Jimmy hike-in camp, I saw no one on the way up from Islip Saddle. A quarter-mile from the trailhead, there was an astonishing display of Poodle-dog bush along the PCT. In 2011, when a large part of Angeles National Forest reopened following the Station Fire, I developed an extensive rash after bushwhacking through Poodle-dog on overgrown trails. After that experience I’ve been more careful around the plant, and haven’t had a bad case since.
Trees were across the trail in a few places. Most were fairly easy to bypass, but a couple were “inconvenient,” such as this big log, about 0.75 mile east of Windy Gap.
As I worked up the switchbacks above the log, to the southwest I could see the observatory and towers on Mt. Wilson. As a result of the damage to Chantry Flat in the Bobcat Fire, Mt. Wilson was on the Angeles Crest 100 Mile course last year, and will be again this year. As the raven flies, Mt. Wilson was only about 16 miles away, but for someone running the AC100, the miles along its challenging course would total well over 50!
For several years I’ve been following the regrowth of conifers in four places along the PCT that were burned in the 2002 Curve Fire. What has been underscored in my informal study is a) trees take a long time to regrow, and b) frequent fires in an area are particularly devastating. Stand #1 (1.5 miles east of Islip Saddle on the PCT) was recovering nicely from the 2002 Curve Fire when it was burned in the 2020 Bobcat Fire. This comparison shows the result. The other three stands continue to recover well, with south-facing Stand #4, west of Throop Peak, growing particularly vigorously.
Ascending the final 400′ of gain on Baden-Powell’s west ridge, I was surprised to see a couple of small patches of snow remained on the north side of the ridge. The snowpack here was nowhere near as big as in 2023, but it was still pleasing to see that a little of the white stuff survived until July.
No out and back to Baden-Powell is complete without a quick stop at Little Jimmy Spring. Today, the water from spring was so cold it was painful to hold my hand in the water flowing from the pipe!

Searching For Another Blue Oak In Upper Las Virgenes Canyon Open Space Preserve
After the Ahmanson Blue Oak in East Las Virgenes Canyon died this Winter, I started to search for another blue oak (Quercus douglasii) in Upper Las Virgenes Canyon Open Space Preserve (aka Ahmanson Ranch). Blue oaks are rare at the southern limit of their range, but I was hopeful that if there was one blue oak at Ahmanson, there might be another.
Typically, blue oak leaves are noticeably different than valley oak leaves. The Jepson eFlora describes the leaf margins of blue oak as being more or less entire, wavy, or more or less lobed. The leaves of the Ahmanson Blue Oak fit this description. Valley oak leaves are usually much more deeply lobed and readily identified.
Recently, while on a run, I noticed an unusual oak near the top of a service road on the western margin of Lasky Mesa. Its leaves are not deeply-lobed and are a bit more dusky than the usual valley oak leaf. But the tree doesn’t look quite the same as the Ahmanson Blue Oak. One difference is that the shape of the leaves is not as uniform as those of the Ahmanson Blue Oak. This might be due to the wet 2022-2023 rain season and the flourish of leaves that resulted. And, as with the Ahmanson Blue Oak, this oak was burned in the 2018 Woolsey Fire, and its trunk is partially hollow.
Based on its leaves, the “West Lasky Mesa Oak” could be a blue oak, blue oak hybrid, or valley oak hybrid. A 2002 study of a mixed stand of blue and valley oaks found that appearance can be misleading. When DNA tested, four of the five hybrid-appearing oaks in the study were not classified as hybrids. Of the four trees deemed most likely to be hybrids, only one oak was intermediate in appearance.
Although it seems unlikely this tree would have been overlooked, I could find no specific reference to the oak in the various studies and surveys done of Ahmanson Ranch. Please get in touch with me if you can provide additional information about this tree or how a DNA analysis can be arranged.
