Topic Is: Things Crawling on the Ground at Ahmanson Ranch

I’ve encountered some interesting things crawling on the ground at Ahmanson Ranch this Fall.

Gopher snakes are the snake I see most frequently at Ahmanson Ranch (Upper Las Virgenes Canyon Open Space Preserve). Recently, I came across this sizable gopher snake crossing the dirt road on the long switchback above the Victory Trailhead. Despite the small size of its head, a gopher snake can consume prey much larger than might be imagined.

Just a few days ago — in virtually the same place as the gopher snake — I encountered a good-sized Southern Pacific rattlesnake serpentining across the dirt road and continuing up the brush-covered hill (video). The snake reminded me of a rattlesnake I photographed near the Victory Trailhead in November 2019. In the Fall, Southern Pacific and other rattlesnakes are said to return to the same den year after year. This rattlesnake had about 13 rattle segments, and the November 2019 rattlesnake about 10. Both were headed in the same direction. Might they be the same snake going back to a den?

On that same run as when I encountered the rattlesnake, I came across this remarkably colored and patterned caterpillar on Lasky Mesa. It turns out to be the caterpillar of a white-lined sphinx moth — a type of hummingbird moth.

A few days later — near the same place where I encountered the gopher snake and rattlesnake — I happened upon this tarantula scurrying across the road. Male tarantulas search for mates in the Fall.

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.

Malibu Creek State Park: Lake Vista Ridge, the Forest Trail, and September Wildflowers

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.

Apple Galls on Scrub Oak Along the Stunt High Trail

Apple Galls on Scrub Oak Along the Stunt High Trail

The eye-catching colors of apple galls are like nothing else in chaparral and impossible to miss. These are on scrub oaks along the Stunt High Trail in the Santa Monica Mountains.

The galls are chemically induced by the larva of the California gall wasp, which uses the gall for food, protection, and to pupate. The rose color appears to result from exposure of the gall to sunlight.

I was descending the Stunt High Trail after visiting Saddle Peak while doing the Topanga Ridge Loop. As in other parts of the Santa Monica Mountains in which I’ve run following Hilary’s deluge, the trails were somewhat more eroded than usual but in OK shape.

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.

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.

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!
