2024 Bridge Fire Perimeter and some trails in the area

October 18, 2024. Updated approximate Bridge Fire Closure boundary for Forest Order 05-01-24-11.

October 13, 2024. Updated Bridge Fire perimeter. Added the Vista Fire perimeter. Added trails from the National Forest System Trails Feature Layer. Added a “guesstimate” of the Bridge Fire Closure boundary. See below for an explanation.

The information in this post may be incorrect or out of date. For official information see the Bridge Fire incident page on Inciweb, the Angeles National Forest updates on Facebook, and the Angeles National Forest website. The perimeters are from the Wildland Fire Interagency Geospatial Services (WFIGS) Group and National Interagency Fire Center (NIFC) website.

Following are several 3D terrain views of the Bridge Fire perimeter from various perspectives:

– Overview of the Bridge Fire perimeter

– View of the Bridge Fire perimeter zoomed in on the Wrightwood area.

– View of the Bridge Fire perimeter zoomed in on the Mt. Baldy area.

– View of the Bridge Fire perimeter zoomed in on the Mt. Baden-Powell area.

The initial view can be changed using the control on the upper right side of the screen, the CTRL key and your mouse, or touch gestures.

As mentioned above, a guesstimate of the Bridge Fire Closure boundary (magenta) for Forest Order 05-01-24-11 (Oct 17, 2024) is now included in the views. The boundary corresponds closely with the PDF map(s) of the closure published on the Angeles National Forest website. There seems to be at least one discrepancy between the Forest Service maps and order description. In the area of East Fork Road, the order description appears to place the closure boundary one section to the west (dashed line). I contacted the Forest Service for clarification, but have received no reply.

Multi-year fire closures have become common on the Angeles. Generally, trails and the land affected by trail are is a minuscule percentage of the area burned. Some jurisdictions reopen parklands and open space areas weeks after a fire with no apparent negative impact on the area’s recovery. Is there science to support multi-year closures of trails in fire areas?

In some cases, closures include trails that are outside of the fire’s perimeter and didn’t burn. These closures may make sense in the short term — when there is a plausible threat from the fire, such as the recent flare-up east of South Mt. Hawkins. But many times, these unburned trails remain part of a long term, multi-year closure. Sometimes it seems the trail just happens to be on the wrong side of a section line, road, or other feature that is convenient to use as a closure border.

Trails that were closed in Forest Order 05-01-24-10, but now appear to be open according to Forest Order 05-01-24-11:

Dawson Saddle Trail
PCT east of Windy Gap to Vincent Gap

Trails outside of the Bridge Fire and Vista Fire perimeters that remain closed according to Forest Order 05-01-24-11:

Devil’s Backbone Trail
Hawkins Ridge Trail
South Hawkins Trail

The following summits are within the updated closure area, but did not burn and are accessible via unburned trails. Peaks marked with ** are just inside of the closure boundary:

Mt. Baldy
Mt. Baden-Powell**
Mt. Burnham**
Mt. Hawkins**
Throop Peak
Sadie Hawkins
South Mt. Hawkins

For those of us passionate about the outdoors, the closure of any trail or peak is a loss. But the long term closure of the most popular trails and peaks in the San Gabriel Mountains without justification would be indefensible. Hopefully, the closure order will be modified when the Forest Service determines the threat from the Bridge Fire is past.

Feeling a Little Like Fall on the Three Points – Mt. Waterman Loop

Rabbitbrush along the PCT east of Winston Peak.

Even with the warm weather, it was beginning to feel a little like Fall in the San Gabriel Mountains. Yellow goldenrod and red California fuchsia bloomed along the trail, and the canyon live oaks were covered in green acorns.

I was back on the Three Points – Mt. Waterman Loop and having a better time of it than in June. The June run had been near the Summer Solstice, with in-the-sun temperatures reaching 100°F. Today’s run was a few days away from the Fall Equinox. Not only was the temperature about 10 degrees cooler, the sun was lower in the sky and less intense.

But much was the same as in June. There was still plenty of whitethorn on the first couple of miles of the Three Points – Mt. Waterman Trail — and a few prickly passages for anyone wearing shorts and short sleeves. Some trailwork had been done higher on the mountain, but a few fallen trees were still on the trail. Most of these were easy to step over, around, under, or through.

There was very little monsoon rainfall this Summer, but consecutive wet rainy season and a tropical storm had already recharged the seeps and small creeks. The creeks were only slightly lower than in June, and the places that had been wet and muddy in June were still wet and muddy. At Waterman Meadow, a few late-season blooms of sneezeweed beamed yellow in the midst of the greens of the grass and ferns.

The high point of the Three Points – Mt. Waterman Trail is near the junction with the trail to the summit of Waterman and the trail that comes up from Highway 2. It’s at an elevation of about 7686′. Including detours to get around downed trees, the junction is a bit more than 6 miles from Three Points. The junction marks the start of a nearly 2000′ descent over 4.7 miles to the PCT in Cooper Canyon.

This morning, I encountered no one on the Three Points – Mt. Waterman Trail and only one pair of hikers on the normally busy Mt. Waterman Trail. Buckhorn Campground was nearly empty. I topped off my water at a convenient faucet at the campground and then started down the Burkhart Trail.

The creek in the canyon below the Burkhart Trail happily bubbled and gurgled, its water easily outpacing me as I descended to the PCT. Some work had been done on the trail to help those hiking to Cooper Canyon Falls cross the muddy seeps. Near one seep, a patch of dazzling red California fuchsia contrasted sharply with the coal black of a tree burned in the Bobcat Fire.

I wouldn’t say the trail has been abandoned, but it’s been quite a while since any trailwork has been done on the PCT between the Burkhart Trail and Cloudburst Summit. A mass of trees is still blocking the trail near the creek crossing at the bottom of Cooper Canyon. As expected following a fire, trees continue to fall on the trail. Parts of the trail along the creek or near seeps are overgrown with “Hey Bear!” willows.

The PCT in Cooper Canyon has been isolated by the 19-year closure to protect the critically endangered mountain yellow-legged frog. In December 2005, Angeles National Forest “temporarily” closed the Williamson Rock climbing area and the PCT between Eagle’s Roost and the Burkhart Trail. This Summer, the Forest Service extended the closure to at least December 31, 2026.

It’s difficult to accept that the Forest Service, conservation groups, and involved agencies have not agreed on a solution. Can’t the short stretch of the PCT that impacts frog habitat be rerouted? Only a few climbs at Williamson Rock directly impact the frog habitat. Does the entire climbing area need to be closed? Can’t bridges, walkways, and other structures be used to protect and even enhance frog habitat? There has to be solution. In 2005, I could not have imagined that 21 years later Williamson Rock would still be closed, and I might not have the opportunity to climb there again.

On this run, it wasn’t necessary to stop at Cooper Camp to cool off. Although the temperature was in the 90s on the south-facing slopes traversed by the PCT, there was a bit of a cooling breeze. This and the lower sun angle made it far more pleasant than earlier in the year.

Continuing up the trail above Cooper Camp, I could see smoke from a flare-up on the north flank of the Bridge Fire. Closures related to the Bridge Fire will further isolate the Cooper Canyon segment of the PCT. Multi-year closures are common on the Angeles, and often the closures include popular trails that were not burned.

From Cloudburst Summit, it’s a little over five miles of (mostly) downhill to Three Points. Most of the running is on an old road bed. Although it can be tedious — especially when it’s hot — the segment is relatively fast-paced. Depending on the year, there are usually a couple of places to soak a hat and pour water over your head. But, as I learned one hot day, a rattlesnake may take exception to your intrusion!

Were Changes in a Pool on Upper Las Virgenes Creek a Precursor to the September 2024 Malibu Earthquake?

Much-diminished pool on Las Virgenes Creek on September 11, 2024, the day before the 4.7 Malibu earthquake.

It was very odd. After persisting in Upper Las Virgenes Canyon for 18 months, the pool on Las Virgenes Creek had unexpectedly receded.

When I’d run past the pool on September 6, it had been full. Just five days later — the day before the 4.7 Malibu earthquake — it had shrunk to a small puddle.

Anyone that hikes, runs, or rides in Upper Las Virgenes Canyon would be familiar with the pool — it’s where the fire road crosses the creek, about a quarter-mile south (downstream) of the pipeline monitoring station and 0.7 mile from the Las Virgenes Trailhead. A use trail has evolved to the east of the road to bypass the pool.

The earthquake occurred on September 12, 2024, at 07:28:21 PDT. That afternoon I ran out to Upper Las Virgenes Canyon and checked the pool again. It was already refilling. Five days later it was nearly back to its normal level.

Was the change in the pool level a precursor to the Malibu earthquake?

The pool is about 11 miles from the earthquake’s epicenter. Water level changes in wells miles from an event have preceded earthquakes similar in size to the Malibu quake. It’s something to wonder about.

Facing a Future of Runaway Wildfires in Southern California

A group of Jeffrey pines on Mt. Waterman killed by the Bobcat Fire with smoke from the Bridge Fire in the distance.

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.

Late Start on the Bulldog Loop

Saddle Peak from the Mesa Peak Mtwy on the Bulldog Loop.

It was near dawn, and I was driving west on the 101 Freeway, going to the Wendy Drive Trailhead to do a run in Pt. Mugu State Park.

I’d just passed Moorpark Road and changed lanes to exit at Lynn Road. Suddenly, the whole car started to shake. The vibration was so intense it took a moment to realize I had a flat tire. [Expletive deleted!] I pulled onto the shoulder of the freeway and cursed again.

After decades without a flat, I had managed to have two in just three weeks. Both were early on Sunday morning and on the way to do a run. The first happened on Angeles Forest Highway while driving to Islip Saddle. That time, I was able to pull into a large turnout and change the tire. Traffic wasn’t an issue. Not so on the Ventura Freeway. The flat was on the driver’s side, and the shoulder was narrow. I called for service.

Apparently, there aren’t many roadside service vehicles out and about before sunrise on a Sunday. An hour and a half later, I was finally headed back to the San Fernando Valley.

I was first in line when Tires Buy Mark opened at 10:00. While waiting for the tire to be patched, I debated a Plan B for a run. Eventually, I decided to do an extended version of the Bulldog Loop. The run would be in the middle of the day, which wasn’t ideal, but it was nearby. It would be an excellent 16-mile run, even if a little on the toasty side.

At 11:30, I started up the short hill at the beginning of the Cistern Trail. Even though it wasn’t an unusually hot day, the temperature in the sun was already in the 90s, and there wasn’t a cloud in the sky.

It was slightly cooler on the trail along Malibu Creek. There was still water pooled in the creek, and I was glad the seasonal footbridge was in place. A pool near the M*A*S*H site was surprisingly large.

A section of Bulldog Mtwy low on the climb.

I expected it to be warm on the Bulldog climb, and it was. I just pretended I was on the second loop of the Bulldog 50K and continued chugging up the hill. Speaking of which… The Bulldog Ultra was the previous weekend, and a new course record was set in the 50K. Anthony Fagundes did the 29 mile course in the remarkable time of 3:30:03. This works out to an AVERAGE pace of 7:15 min/mile! His race analysis on Strava lists a split on the downhill on Mesa Peak Mtwy fire road at 5:25 min/mile. I don’t have the exact time, but on the first loop it looks like he did the Bulldog climb — from Crags Rd. to Castro Crest Mtwy — in about 30 minutes.

It took me a little longer than that to get up Bulldog. There was a noticeable drop in temperature as I worked up to the top of the long climb. On Castro Crest and Mesa Peak fire roads, the temperature was a relatively comfortable 80-something. The breeze from the ocean was intermittent, but when present, felt like air conditioning.

There weren’t many wildflowers. One interesting exception was Santa Susana tarweed (Deinandra minthornii). It was blooming on the sandstone rocks where the Backbone Trail goes through a prominent rock gateway, east of the Corral Canyon Trailhead.

Santa Susana tarweed along the Backbone Trail, east of the Corral Canyon Trailhead.

The plant has a California Rare Plant Rank of 1B.2, which means it is considered “rare, threatened, or endangered in California and elsewhere…” The plant normally blooms after Winter rains. In the ANF technical notes** accompanying its description on SMMflowers.org, B. A. Prigge & A. C. Gibson describe how the plant may produce out-of-season flowers in the Summer, following a wet rain season with late Spring precipitation.

Here is an interactive, high-resolution, 3D terrain view of a variation of the Bulldog Loop that starts at the Cistern Trail. The notations assume the route is being done counterclockwise. An optional out-and-back on the Forest Trail is shown as a red track. Two routes are shown for crossing Malibu Creek in Tapia Park. One route uses a trail that rock-hops across the creek, and the other the bridge on Malibu Canyon Road, near the Piuma Road junction.

The option on Malibu Canyon Road requires crossing the highway twice. There is a pedestrian walkway on the east side of the bridge and a traffic light and crosswalk at Piuma Road. The trail that crosses the creek directly can be a little tricky to find because of other use trails in the area. When there is heavy rain, the flow may be too high to cross the creek safely.

Today, I decided to use the highway. There was a never-ending line of cars headed to and from the beach. It probably would have been faster — and safer — to use the trail. After crossing the creek on the highway bridge, and before doing the climb on the Tapia Spur Trail, I topped off my water at a faucet in the Tapia Day Use Area. Later, I also grabbed a quick drink at the water faucet next to the restrooms at the main Malibu Creek State Park parking lot.

From the main parking lot, it’s about 1.4 miles along Crags Road to the bottom of the Lookout Trail, and from there another three-quarters of a mile back to the Cistern Trailhead on Mulholland Highway.
