Seventh Wettest Water Year Results in Spring-Like Scenery Along L.A. Area Trails

Downtown Los Angeles (USC) finished the 2022-2023 Water Year with 31.07 inches of rain, making it the seventh wettest on record in Los Angeles. The rainfall total includes about three inches of rain from former Hurricane Hilary as it moved through Southern California as a rare tropical storm and post-tropical cyclone.

The effects of all that rain can be seen on just about any trail in Southern California. It has resulted in a false Spring in many areas, with greening hills, out-of-season wildflowers, flowing creeks, and profuse growth throughout the area.

This morning, I returned to the Top of Reseda and Topanga State Park to do a variation of the Trippet Ranch Loop and continue exploring and enjoying the unusual conditions.

After running up to the Hub, this variation does an out and back to Temescal Peak and Temescal Lookout. After returning to the Hub, the route continues on Eagle Springs Fire Road down to Trippet Ranch. From Trippet Ranch, it works back to the Top of Reseda using the Musch and Garapito Trails and connecting sections of fire road. This interactive, 3D terrain map shows a GPS track of the trail run.

Visiting Temescal Peak and Temescal Lookout increases the run’s mileage from 12.5 miles to 16. On a clear day, the runner is rewarded with far-reaching views of the coast, West L.A., Downtown, and the surrounding mountains.

While most of the roads and trails on this route are frequently used and in decent condition, the Garapito Trail has been overgrown all Summer. As of October 8, it was still overgrown. Some people I’ve encountered on the trail were OK with this, but others haven’t been so happy. If desired, the trail can be bypassed by continuing to the Hub on Eagle Rock Fire Road and retracing your route back to the Top of Reseda.

Here are a few photos (and notes) taken on the run.

A Second Spring at Ahmanson Ranch

It’s been about a month and a half since Tropical Storm Hilary soaked Southern California with record-setting rainfall.

The unusual amount of Summer rain has resulted in a second Spring at Ahmanson Ranch, with some plants behaving as if it were March or April.

Not only are plants growing as if it were Spring, some are flowering. The lupine pictured above usually blooms at Ahmanson Ranch in March, April, and May. Now, as a result of T.S. Hilary’s rain, it’s flowering in October!

Those plants that usually flower in the Fall, such as telegraph weed, vinegar weed, and common sunflower, are much more widespread than usual.

Here are a few photos of the unusual conditions at Ahmanson Ranch (Upper Las Virgenes Canyon Open Space Preserve).

Spring-like conditions are present in many areas of Southern California. On Sunday, I ran the Phantom Trail in Malibu Creek State Park. Some sections were so overgrown that it was challenging just to navigate the trail, much less run it. Ticks were also a problem.

I took a few tentative steps into the dense brush and stopped. It was just too overgrown. I backtracked a few feet to the overlook at the top of Lake Vista Trail and reconsidered. If it was this overgrown all along the ridge, it was going to take a long time to get to the summit.

I was trying to get to the top of “Lake Vista Butte,” a high point along a prominent ridge of volcanic rock that stands between Reagan Ranch and Malibu Creek. The ridgeline and summit provide a unique perspective of Malibu Creek, Century Lake, Goat Buttes, Malibou Lake, and much of Malibu Creek State Park.

I dove back in, walking on top of a dense mat of dried deerweed and then working around a thicket of laurel sumac. Even if it was buried in a tangle of chaparral, it helped to know there was a path along the ridge. As I worked east along the ridgeline, the path would briefly emerge, only to disappear under another mass of scrub and brush.

In places, enterprising orb-weaver spiders had constructed intricate webs across remnants of trail. Their artwork was easy to spot in the morning sun, and even though their webs blocked the trail, they could not be disturbed. At least the spiders were out in the open. A rattlesnake could be anywhere in the rocks and brush and might not be kind enough to give a warning.

The route along the ridge wasn’t technically challenging, but like the spider’s web, required patience to complete. Low in the sky, the morning sun complicated the route-finding, making it more difficult to see sections of the trail and link them together.  Far outweighing these inconsequential difficulties were the exceptional views of Malibu Creek State Park’s crags, canyons and mountains while traversing the ridge.

As often happens, the return to the Lake Vista Trail took less time than the ascent. Back at the overlook, I began retracing my steps down the Lake Vista and Deer Leg Trails and over to the top of the Cage Creek Trail. I was headed down to Malibu Creek to check the condition of the Forest Trail.

The Forest Trail is the “Walden Pond” of Malibu Creek State Park. Bordered by Century Lake on one side and the steep slopes of a rocky butte on the other, it is a contemplative place and one-of-a-kind habitat. It is home to towering coast redwoods, sprawling live oaks, sweet-smelling California bay, and water-loving California sycamores. Deer, ducks, bullfrogs, herons, hawks, falcons, and other wildlife may be seen here.

Fallen trees have been accumulating on the Forest Trail for months. On my last visit, following T.S. Hilary’s passage, another large oak had fallen near the beginning of the trail, making it unusable. Today, I was happy to find that the trees had been cleared, and the Forest Trail could be followed to its end at Century Lake Dam.

Here are a few photos taken along the way, including some wildflowers that usually don’t bloom this time of year.

Looking For Local Impacts of Tropical Storm Hilary

Update September 14, 2023. Mustard is sprouting along Ahmanson’s fire roads, and more surprising — a few mushrooms.

Update September 8, 2023. The new grass from T.S. Hilary’s rain is coming in nicely at Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch).

Tropical storms are a different kind of weather beast than usually seen in Southern California. The warmer air associated with such storms can carry much more water and produce unusually high amounts of precipitation.

The rain resulting from Tropical Storm Hilary shattered many daily and monthly records. Over decades of record keeping, most stations in the greater Los Angeles area had previously measured only a trace of rain on August 20 or 21, or at best, a few hundredths of an inch. Some stations had never recorded any rain on these days.

This Google Earth image with precipitation data from the California-Nevada River Forecast Center (CNRFC) shows the remarkable rainfall totals across Southern California for the 24-hour period ending at 5:00 a.m. on Monday, August 21, 2023.

The highest rainfall amounts occurred where the precipitation was enhanced by mountainous terrain. The northeast-facing slopes of the eastern San Gabriel Mountains, near Wrightwood, were ideally positioned in Hilary’s circulation to enhance rainfall. The Big Pine RAWS recorded over 6 inches of rain for the storm, Lewis Ranch slightly over 7 inches, and Lytle Creek nearly 10 inches.

Detailed observation and impact reports for Hilary are available from NWS Los Angeles/Oxnard, NWS San Diego and the Center for Western Weather and Water Extremes.

This crossing of Las Virgenes Creek was about the same as before Hilary.

Curious to see some of the local impacts of the storm, I ran at Ahmanson Ranch on August 22 and then a few days later at Malibu Creek State Park.

My West Hills weather station, about three miles from Ahmanson Ranch’s Victory Trailhead, recorded 3.86 inches of rain for the storm. After an initial technical hiccup, the Cheeseboro RAWS, overlooking Las Virgenes Canyon, recorded 3.52 inches of rain. This and other data suggest rainfall amounts in the Ahmanson area of at least 3.5 – 4.5 inches.

My Ahmanson run started at the Victory trailhead, went out East Las Virgenes Canyon, through part of Las Virgenes Canyon, and then up to Lasky Mesa. With that much rain, I was sure I would be wallowing in the mud and wading the creek crossings. But my shoes didn’t even get muddy!

There was certainly some mud, puddles, and a little erosion, but the impact of Hilary on Ahmanson was surprisingly minor. The ground must have been desiccated because Las Virgenes Creek had almost no increase in flow. The creek crossings near the pipeline station and south of the station were essentially the same as before Hilary. Even more surprising, there was no water at the crossing a little north of the Las Virgenes Trailhead.

As Hilary moved northward in California, the counterclockwise circulation of the storm increased the rainfall in the Santa Monica Mountains. Automated RAWS stations in Topanga, the Malibu Hills, and in Malibu Canyon recorded 4.0 to 4.5 inches of rain during the storm. CNRFC gridded precipitation data indicated higher amounts in some parts of the range.

On August 27, I ran the Bulldog Loop in Malibu Creek State Park. The run started at a small parking area at the junction of Malibu Canyon & Piuma Roads. As I was running up the Tapia Spur Trail, I wondered if State Parks had — as a precaution — removed the seasonal bridge across Malibu Creek on the Crags Road Trail. On August 19, the day before Hilary drenched the area, the bridge had been in place for the Bulldog Ultra. If it wasn’t removed, did Malibu Creek get high enough to damage it?

Once again, I need not have worried. The bridge was just fine, and the reeds in the water near the bridge suggested only a modest increase in streamflow.

It’s unusual for the slopes along Bulldog fire road to be this green in Summer!

It looked like Malibu Creek State Park received more rain than Ahmanson Ranch. There was slightly more erosion on the dirt roads and some small sluffs/slides, including one tree that slid onto Mesa Peak Mtwy fire road. A tree had also fallen near the beginning of the Forest Trail.

Back at Ahmanson on August 31, things were drying out, but it was beginning to look like Spring. Grass was sprouting all over Ahmanson Ranch. It will be interesting to see if the grass survives the inevitable heat and grows enough to turn the hills green. The little bit of rain and cooler weather over Labor Day weekend will help. Some out-of-season wildflowers could also result from a false Spring.

Yesterday, I did a run in Topanga State Park, and the story was much the same. There was some minor erosion on the fire roads, but none of the larger sluffs and slides seen during the rainy season. There was no new damage to the Musch or Garapito Trails. It did look like the flow had increased on Garapito Creek with Hilary’s rain, and there was a still little water in the mainstem of the creek.

Manzanita Trail Plus Mt. Baden-Powell

Update September 3, 2023, 1:15 p.m. Caltrans Quickmap is showing Angeles Crest Highway (Hwy 2)  is now open between Grassy Hollow and Vincent Gap.  Caltrans Road  Conditions says the closure is “5 mi west of Big Pines.” Google Maps and Waze still show the section between Grassy Hollow and Vincent Gap as closed.

Update August 23, 2023. The Big Pines RAWS recorded 6.26 inches of rain, and Lewis Ranch RAWS 7.04 inches from T.S. Hilary. The heavy rain on the north-facing slopes of the eastern San Gabriels may have produced debris flows in the washes crossed by the Manzanita Trail. Excessive runoff may have done more damage to stabilized sections of the Manzanita Trail where it crosses steep slides above Paradise Springs. According to CalTrans, the previously open section of Angeles Crest Highway (Hwy 2) between Grassy Hollow and Vincent Gap is currently closed.

I’d been thinking about doing the South Fork Loop, a challenging loop that I usually start at Islip Saddle. The route descends the South Fork Trail to South Fork Campground (4,565′) and then climbs all the way to the top of Mt. Baden-Powell (9,399′), using the Manzanita Trail and PCT. From the top of Baden-Powell, the PCT is followed back to Islip Saddle.

But there were a couple of problems with this idea. First, the road to Islip Saddle — Angeles Crest Highway — was closed. More importantly, parts of the South Fork Trail were burned in the Bobcat Fire, and heavy snow and rain may have damaged the South Fork Trail or Manzanita Trail.

One of the washes crossed by the Manzanita Trail, about a mile below Vincent Gap.

The road closure would be easy to work around — the loop could be started at Vincent Gap. But I definitely needed to check the condition of the South Fork and Manzanita Trails. The loop is difficult, even when the trails are in good shape.

I decided to check the Manzanita Trail first. If that trail had issues, then the condition of the South Fork Trail didn’t matter.

So that is what I was doing today. The plan was to run the Manzanita Trail from Vincent Gap down to South Fork Campground, then turn around and — just like on the South Fork Loop — take the Manzanita Trail and PCT to the top of Mt. Baden-Powell.

Brush and debris deposited on the Manzanita Trail a couple of miles below Vincent Gap.

I woke early on Sunday and arrived at Vincent Gap at about 6:45 a.m. With much of Angeles Crest Highway closed, I shouldn’t have been surprised that the main parking lot was already full. I nabbed the last spot in the overflow area across the highway. I could only imagine what it must be like on the trail up Baden-Powell.

But I didn’t have to worry about that — not for a while. I grabbed my pack from the back of the car and started jogging down the Manzanita Trail. On that trail, I probably wouldn’t see anyone!

As would be expected on a little-used trail after a hard Winter, the Manzanita Trail was a bit of a mess. In addition to being generally overgrown, there were fallen trees, brush deposited on the trail by runoff or avalanches, minor washouts, and other damage. These slowed the pace but weren’t too much of a problem.

On the other hand, there is a section of the Manzanita Trail that could be a serious issue. It is where the trail crosses several steep, loose, stabilized slides. This area is about 4.4 miles from Vincent Gap and 1.4 miles from South Fork Campground. This section of the trail is almost always damaged, but on past adventures, had always been passable. How bad was it going to be today?

The answer is — pretty bad. As I started across the first slide, it looked like it would go just fine, but then I looked closer. One of the abutments on the down-slope side of the trail had completely given way. The trail had collapsed, leaving only a narrow slice of crumbling dirt along the base of the up-slope barrier. I would have to use the barrier to get past, and it wasn’t in the best shape. I’m sure people have done this, but it seemed like a bad idea. I could see no straightforward way around the collapsed trail. Disappointed, I turned around and started working back up the trail toward Vincent Gap.

I’d been running for a few minutes when I came across a “lightning tree.” These are trees that have been struck by lightning and have a scar spiraling down their trunk. I’ve photographed a number of them. Some are in a location that you would expect to be struck by lightning, but just as many are along seemingly unexposed sections of trail. Once, I was running down the PCT below Mt. Hawkins, well below the crest, and a tree 50 yards down the slope was smoking from just being struck.

On the way back up to Vincent Gap, there would be a little route-finding fun. The Manzanita Trail crosses some small debris-filled washes. Over time, paths develop through the rubble but can be intermittent and indistinct. Debris flows can destroy a part of nearly all of a path.

The wash in Dorr Canyon is the largest crossed by the Manzanita Trail. Keeping in mind that Tropical Storm Hilary may have changed things, on August 13th, the path across the wash was mostly intact. One gotcha was that on the west side of the wash, the path ended short of the Manzanita Trail.

Did I mention the gnats, stinging nettle, and Poodle-dog bush? Oh, the gnats. On the way down the trail they weren’t too bad, but as the temperature warmed, they became increasingly annoying and persistent.

When doing the South Fork Loop, I usually stop for water at the stream that feeds Icy Springs. The trail was overgrown near the stream, and mixed in with the greenery was some stinging nettle. Even knowing it was there, I managed to brush against it on the way down the trail and then again coming back up.

There was also a little Poodle-dog bush on the trail about two miles down from Vincent Gap in a small area that had been burned. As long as you noticed it, it was easy to avoid.

What the heck? As I topped out at Vincent Gap, the sounds of revelry came from across the highway. It was party time in the Baden-Powell parking lot! A large group of people were gathered at the west end of the lot, near the trailhead. Were they preparing to do a mass ascent of Baden-Powell? I quickly refilled my hydration pack, grabbed some food, and headed up the PCT.

Once I escaped the craziness of the parking lot, it turned out to be one of the most pleasant ascents and descents of Baden-Powell I’ve done. Even with the machinations of the Manzanita Trail earlier in the morning and the additional vertical gain, Baden-Powell couldn’t have gone better. Very few hikers were on the trail, everyone was super-friendly, and when I reached the summit, it was empty — at noon, on a Sunday, in August!

Dealing with the Heat on Strawberry Peak and San Gabriel Peak

Last weekend I’d considered doing a run from Red Box, but finally decided to go to higher elevation and do a combination run and climb.

Blazing star.

The puzzle to solve this weekend was to find a run that was closer to home, higher than the Santa Monica Mountains, and had a “decent amount” of elevation gain. The solution put me right back at Red Box, doing two of the most popular peaks in the Front Range — Strawberry Peak (6164′) and San Gabriel Peak (6161′).

I’d done these peaks as a duo several years ago. The basic details remain the same and are described in this post.

The main difference is that the 2018 run/hike was on a cool day in March, rather than a hot day in August. In 2018, I did San Gabriel Peak first, then Strawberry. The order didn’t matter. The temperature on both peaks that day was mostly in the 40s.

Today, it was essential to do Strawberry first, and get started early. The use trail between Lawlor Saddle and Strawberry’s summit faces south and east, and has very little shade. It’s steep and strenuous an no fun at all in the hot sun.

I left the Red Box parking lot at about 6:00 a.m. On the way up, the temperature ranged from the mid-50s to the mid-70s. On the way down, in some places it was already in the 90s. While it was hot in the sun on the upper part of the mountain on the descent, the traverse around Mt. Lawlor on the Strawberry Trail was still mostly in the shade and a relatively cool 75 to 80 degrees.

San Gabriel Peak isn’t the solar oven that Strawberry is. Much of the Bill Riley/Mt. Disappointment Trail faces north and a scrub oak forest provides some shade. Continuing up San Gabriel Peak after doing Strawberry, the temps were generally in the low to mid-80s.
