Bridge Fire Perimeter and Some Area Trails

2024 Bridge Fire Perimeter and some trails in the area

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. The timestamp for the perimeter is the poly_CreateDate specified with the perimeter data.

GPS tracks of some trails in the area are also shown. Placename and trail locations are approximate and may be incorrect.

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

Back to Baden-Powell – August 2024

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.

It was great to be back on the Rim Trail! One of the most underappreciated trails in Angeles National Forest, the 3.6 mile trail was closed in October 2020 because of the Bobcat Fire. It finally reopened in June of this year (2024).

This morning’s run had started at the top of the Kenyon Devore Trail from the same turnout on Mt. Wilson Circle Road as two weeks before. This time, instead of running down Mt. Wilson Road, I had descended a short distance on the Kenyon Devore Trail and turned right (east) on a half-mile long trail that connects to the main Mt. Wilson parking lot. From there I followed the “Authorized Vehicles Only” road toward the observatory about a quarter-mile to the signed start of the Rim Trail. Interpretive signs along the road note some of the area’s plants and trees.

When done as a counterclockwise loop from Mt. Wilson, the Rim Trail switchbacks down Mt. Wilson’s steep northeast ridge and then contours along the north side of the West Fork – Santa Anita Canyon divide to Newcomb Pass. Along the way are spectacular views of the Mt. Wilson Observatory complex, the canyons of the West and East Forks San Gabriel River, and the high country of the San Gabriel Mountains. On a clear day, Saddleback, San Jacinto Peak, and San Gorgonio Mountain can be spotted from the trail. To the north, the vast Mojave desert stretches out from the foot of the mountains.

Even though it was closed for nearly four years, the Rim Trail was in remarkably good shape. The trail dips into and out of the Bobcat burn area as it works down the ridge and along the divide. Much of the trail was unscathed, but some sections were severely burned. Sadly, this beautiful bigcone Douglas-fir was destroyed.

Poodle-dog bush marks the stretches of trail burned in the Bobcat Fire. With care, it was generally avoidable, as was the abundant poison oak found on some sections of the trail. (Like poison oak, Poodle-dog bush causes a rash in many people.)

On the way down the Rim Trail, I’d debated which route to take from Newcomb Pass. One option was to run over to Newcomb Saddle and take Rincon-Redbox Road to West Fork. Another was to follow the Gabrielino Trail to Devore Camp and then West Fork. The single-track route through Devore Camp is a more interesting option and is usually my choice.

As I neared Newcomb Pass, I was surprised to see recent trailwork on the isolated stretch of trail. This was a hopeful sign the Gabrielino Trail between Newcomb Pass and Devore Camp might be in decent shape.

At Newcomb Pass, all signs of any trailwork ended. I looked at the first few overgrown yards of the trail connecting to Newcomb Saddle and thought, “I’ll give the Gabrielino Trail a try.” I could see an ill-defined path where the Gabrielino Trail should go and tried to follow it. No go. A lower path also appeared to be a dead end.

I enjoy the challenge of following little-used trails, but today was more interested in running than bushwhacking. Retracing my steps, I returned to the trail connecting to Newcomb Saddle.

It wasn’t as bad as I initially thought. The trail was a bit overgrown, but was on an old roadbed and pretty easy to follow. (Later, I discovered I had a bite from a larval tick, which I’m sure I picked up in the Newcomb Pass area.)

Rincon-Redbox Road was wide open and in great shape. When I reached the point where the Gabrielino Trail crosses the road, neither direction on the trail looked particularly promising. Up the trail looked overgrown, and down the trail was blocked by a newly constructed drainage conduit. The Gabrielino Trail is a National Recreation Trail in a National Monument, so should (hopefully) be fully restored.

Running down Rincon-Redbox Road and lost in thought, I was somewhat startled to see a red truck round a bend. I was even more surprised when it turned out to be race director and trailmaster Gary Hilliard. Gary and Jose were out the weekend before the AC100 trying to chase down a couple of logs — one reported to be blocking access to the Newcomb Saddle aid station and another on the Gabrielino Trail “a half-mile from West Fork.”

I’ve had the privilege of running in all of Gary’s ANFTR/Mt. Disappointment races. No one works harder or is more dedicated to the trails of Angeles National Forest and trail running. I didn’t recall a log blocking the road, but it would only take Gary a few minutes to drive up to the aid station and be sure. With cruise control on and lost in thought, I continued running down to West Fork.

At West Fork, I stopped at “the pipe” to get water and cool off. From here, it’s a memorable 5-mile, 2600′ climb to the top of the Kenyon Devore Trail.

I’d been here two weeks before. The Rim Trail – Newcomb Saddle – Kenyon Devore Loop is the mirror image of the Mt. Wilson – Red Box – Kenyon Devore Loop. Two weeks ago it was around 10 degrees warmer and humid. I’d bonked on the climb, and wasn’t looking to repeat that experience today.

This morning – except for a couple of rattlesnakes – the run from West Fork couldn’t have gone better! I even jogged some of the less steep sections of the Kenyon Devore Trail!

As I drove east on the 210 Freeway, a long bolt of lightning erupted from high in the clouds and pierced the valley below. The thunderstorm near Mt. Lukens looked spectacular. It was backlit by the rising sun, and intermittent lightning flashed against its dark gray clouds.

Theoretically, I was headed to Mt. Wilson. It was July. It was hot. It was time to get on the ANFTR/Mt. Disappointment race course! But was that going to be a good idea? A slight chance of a thunderstorm was forecast for the afternoon and already there was an active storm right in front of me.

The Angeles National Forest Trail Races (aka Mt. Disappointment) is a popular event usually run in the heat of Summer after the Fourth of July. Because of the pandemic, Bobcat Fire, and trail and road closures, the race has been on hiatus since 2020, but a new race date appears to be in the works!

Another ragged bolt flashed horizontally across the clouds. The cell looked isolated and appeared to be moving to the north. I decided to take a chance and bet that the morning storm was a quirk. Still, it suggested a real possibility of a thunderstorm later in the day.

About the time I passed Trail Canyon on Big Tujunga Canyon Road, it started to rain, and the rain continued much of the way to Red Box. The activity was actually more extensive than the cell near Mt. Lukens — a band of thunderstorms had swept through the San Gabriel Mountains between Mt. Lukens and Mt. Wilson.

Mt. Wilson Road was still wet as I started down the first leg of the ANFTR/Mt. Disappointment 60K/50K/25K courses. If you have to run on pavement, running downhill on super-scenic Mt. Wilson Road after a thunderstorm is about as good as it gets! The cleansed atmosphere and vivid smells in the wake of the storm were remarkable — as were the views down into the canyon of the West Fork San Gabriel River.

This morning, I was doing the 25K course, but all the distances follow the same route to Red Box. They start by running down Mt. Wilson Road to Eaton Saddle and then following Mt. Lowe Fire Road through Mueller Tunnel to Markham Saddle and the San Gabriel Peak Trail. The San Gabriel Peak Trail leads up to the Mt. Disappointment service road and, surprisingly, the high point of the 60K/50K/25K courses. This stretch of service road is higher than the start/finish on Mt. Wilson!

Even if you have run a trail many, many times — and think you’re familiar with it — sooner or later, you’re going to encounter something you didn’t expect. From the Mt. Disappointment service road, the ANFTR/Mt. Disappointment courses turn onto the Mt. Disappointment/Bill Riley Trail. After the first couple of switchbacks, there were an increasing number of cut limbs on the trail. Initially, the cuttings were not much of an issue, but became worse as I continued down the trail.

Partway down, I encountered two very upset hikers who had lost the trail. They had just decided to leave the trail and hike on the service road. They cautioned me that the section where they had problems was just below. They weren’t kidding. I’ve done this trail innumerable times and at one point also had difficulty locating it. I had to wade through an expanse of cuttings to stay on the trail.

I’ve been on trails impacted by forest thinning projects before. The crews that worked on those projects at least made an effort to keep the trails clear. No such attempt was made here — the cuttings were left where they fell, and if that was on the trail, too bad!

It was a relief to get off the Mt. Disappointment/Bill Riley Trail and down to Mt. Wilson Road and Red Box.

Unlike last year, Rincon-Red Box Road was in great shape. It was so well-graded that a Prius might have been able to drive down to West Fork. Much of the 5.5 miles down to West Fork are in full sun, so the temperature has a substantial impact. In the 2019 ANFTR/Mt. Disappointment 50K, the thermometer on my pack read about 80 degrees. In the 2017 50K, the temp on the same stretch was about 100 degrees. Today, it was around 90.

Whatever the temperature, there are excellent views down the West Fork and of the Mt. Wilson area. The towers on Mt. Wilson always look tantalizingly close, and the climb up Strayns Canyon doesn’t look that bad. (Ha!) Like last year, there were four or five creek-like crossings of the West Fork San Gabriel River.

The area around the spring at West Fork was a bit overgrown, but a trampled path through the grass below the cistern led to the outflow pipe. I refilled my hydration pack and drank my fill before setting off on the Gabrielino Trail. With the temperature in the sun at West Fork around 95, I should have spent more time at the spring cooling down.

It’s only about 1.6 miles from the spring to where the Kenyon Devore Trail forks left off the Gabrielino Trail, but it often seems longer. Probably because I’m anticipating the turnoff and don’t want to miss it. This morning, it was also the hottest stretch on the course, with the temperature in the sun topping out at around 100 degrees.

Based on some recent runs, I expected the Poodle-dog bush on this stretch to be a problem, but most of the Poodle-dog bush had been trimmed or was wilting. It wasn’t the only thing that was wilting. Shortly after turning off the Gabrielino Trail and onto the Kenyon Devore Trail, the combination of heat and humidity hit me like the proverbial brick. I had to back off the pace.

Not long after that, I was startled by a runner coming up behind me. It turned out to be another runner from the West San Fernando Valley! Charlie was training for UTMB and putting in a tough 27-mile, 8700′ gain day. We had a great conversation about races, running, and adventures in the mountains. Despite the heat, he was moving well and soon disappeared up the trail.

I continued chugging up the trail, noting familiar features as I climbed higher and higher. Eventually, the white dome of the Hooker 100 inch Telescope came into view, and I knew I just about done!

As I worked up the final half-mile of trail, I could see only a couple of  isolated build-ups of cumulus clouds. One was over the desert  and the other was to the east near San Gorgonio.  The sky over Mt. Wilson was mostly clear.

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!
