It was a little past 3:00 in the afternoon when I passed this straight-backed wooden chair along an Ahmanson Ranch trail. The Tempe thermometer clipped to my pack read over 100 degrees.
It gets REALLY hot at Ahmanson Ranch (Upper Las Virgenes Canyon Open Space Preserve). In the direct sun the temperature can be 10°F-15°F hotter than in the shade, and there is very little shade at Ahmanson. In-the-sun temperatures of 100°F or more are common in the Summer but can occur just about any time of the year.
There are two weather stations I use to get an idea of the weather conditions at Ahmanson Ranch — the Cheeseboro RAWS and Valley Circle Estates Weather Underground station. Weather station thermometers are usually shielded from the direct sun by a white, ventilated enclosure. The Cheeseboro RAWS includes a measurement of the “Fuel Temperature.” This is generally a better indication of the temperature experienced by a runner, hiker, or rider in the direct sun.
Update on July 29, 2023. Rounding the temperature to whole degrees, my West Hills weather station recorded a high of 100°F, or higher, for 15 consecutive days this July (7/13/23 to 7/27/23). The station is about three miles from the Victory Trailhead at Ahmanson Ranch.
You might not see it from the Los Angeles side of the mountains, but there is still some snow on the higher, north-facing slopes of the San Gabriel Mountains.
During and after storms, snow-laden southerly winds dump their load on the backside of the crest, creating deep drifts, cornices, and compacted slabs of snow. This snow is often the last to melt, not only because it doesn’t face the sun, but because there is more of it.
This morning, I was doing an out-and-back from the Windy Gap Trailhead in the Crystal Lake Recreation Area to Mt. Baden-Powell. The Windy Gap Trail climbs 1730′ in 2.6 miles, joining the PCT at Windy Gap. From there the trail follows the spine of the San Gabriels past Mt. Hawkins, Throop Peak, and Mt. Burnham to Mt. Baden-Powell.
I usually do this run from Islip Saddle, but with Angeles Crest Highway (Highway 2) closed between Red Box and Vincent Gap, the Islip Saddle trailhead isn’t accessible.
Whether you start at Crystal Lake or Islip Saddle, the length of the run is about the same — a bit over 16 miles. The main difference is that the Windy Gap Trailhead is about 800′ lower in elevation. On the plus side, the Windy Gap Trail is very scenic; on the minus side, it faces south and can bake in the midday sun.
On today’s run, I encountered the first snowbanks at an elevation of 8870′, near the Dawson Saddle Trail junction. Out of curiosity, I tried to follow the trail and soon realized that was a mistake. I was more or less forced to skirt the downhill side of a lengthy and deep drift — it being too steep and icy to cross directly.
For the remainder of the run, I switched to the early season tactic of staying on the crest when the trail deviated onto shaded, north-facing slopes. These areas might have significant snow on the trail. This only happens in a few places, such as when the PCT works around Mt. Burnham. There is a use trail that ascends the west ridge of Mt. Burnham, and then returns to the PCT.
The conditions today are reminiscent of those found here in early July 2005. July 3rd of that year there was still snow on the summit of Baden-Powell, and there was deeper snow in the areas where there was snow today. We had a lot of storms this rain season, but in Rain Year 2004-2005 Downtown Los Angeles (USC) recorded about 9 inches more rain than during the 2022-2023 rain year!
Starting at the Wendy Drive Trailhead, I’d crossed Satwiwa, run down Danielson Road, rock-hopped across Upper Sycamore Creek, and picked up the Old Boney Trail. The condition of the Old Boney Trail between Danielson Road and the Fossil Trail junction was better than expected. Maybe the trail was going to be in good shape after all.
Wrong! Once I passed the turnoff to the Fossil Trail, the vegetation closed in. In places it was so thick I couldn’t see the trail at my feet, much less a few yards ahead. All I could do is smile and work my way through it. Everything was overgrown — bushes, grasses, wildflowers. And everything was wet with dew. A hundred yards past the Fossil Trail, I was soaked from head to toe.
I tried to see the positive. It was an amazing display of the effect of a wet rainy season. Without trail work and use, it wouldn’t take long for the trail to be completely consumed.
The Old Boney Trail continued to be a tangle of chaparral for about two miles — until I reached the Backbone Trail at Blue Canyon. At that point, it becomes part of the Backbone Trail system, and I was relieved to see that some work had recently been done on the trail.
As I worked up the Backbone Trail toward the Chamberlain Trail junction, I recalled other times I’d run to Serrano Valley using Old Boney. What would the condition of the trail be beyond this point? I’d been on that part of the Old Boney Trail following a wet rain season and knew how overgrown it could be. Some refer to that section of trail as “tick alley.”
But when I got to the junction, surprise, surprise, the Old Boney Trail had been trimmed. More than two miles of trail were groomed. It was good all the way to the Serrano Valley Trail and partway into Serrano Valley. The trail in Serrano Valley was a little overgrown, but NOTHING like the Old Boney Trail between the Fossil and Backbone Trails.
Part of the fun of doing this route is all the stream crossings in Serrano Canyon — what is it 13 or 14? Today, most of these could be done without getting your shoes wet — especially if you have poles. I didn’t have poles, and my shoes and socks were already wet, so I didn’t worry about keeping them dry. Some sections of the Serrano Canyon Trail were also overgrown, but not bad. However, there was a lot of poison oak, some of which wasn’t avoidable.
After getting a drink of water at the faucet at the junction of the Serrano Canyon Trail and Sycamore Canyon Fire Road, I headed up-canyon. Almost immediately, the fire road crossed Big Sycamore Canyon Creek. I did this first crossing without getting my shoes wet, but nine more crossings followed, and most resulted in soaked shoes. The water crossings and wildflowers helped distract me from the five mile run up Sycamore Canyon to the Upper Sycamore Trail.
Getting off Sycamore Canyon Road and onto the Upper Sycamore Trail was a relief. Whatever run I do from Wendy Drive, I always finish it via this trail. The trail gets enough use that it was in good shape. This time all the creek crossings could easily be rock-hopped.
Even with a few tedious sections, it was an adventurous and mostly enjoyable 20 miles. Here are some photos taken along the way.
After doing a climbing /trail running combo in Pt. Mugu State Park last Sunday, I headed back to Wendy Drive this morning to do a trail run to Mugu Peak and back.
The plan was to get in a long run (20 miles) with fewer “get your feet wet” stream crossings, and also check out the conditions on several trails I hadn’t done this year.
So much for keeping the feet dry! The temp was in the mid-30s when I turned off Big Sycamore Canyon fire road and onto Wood Canyon fire road. The main creek draining Sycamore Canyon cuts across the fire road here, and there was no way I was going to get across it without wading. Some smaller stream crossings followed, ending with Wood Canyon Creek.
Several trails/roads converge at the top of Hell Hill, and I turned right onto the fire road that leads to the La Jolla Valley Loop Trail. I like to do Mugu Peak as part of a counterclockwise loop that combines segments of the La Jolla Valley Loop Trail and Mugu Peak Trails.
Long stretches of the La Jolla Valley Loop Trail between the walk-in camp and Mugu Peak were sopping wet. I’ll be curious to see how quickly it dries out, but today (April 2) it was really, really wet.
Mugu Peak was pretty much as it always is on this side — busy and steep. The steepness of the “Direct” trail helped wring the water from my Ultraglides and Injinji socks. By the time I reached the top, my feet were only damp.
Mugu Peak is VERY popular, and there are almost always a few people taking in the wide-ranging views from the summit. Most do the short, steep hike from PCH on the Chumash Trail. A few start at the Ray Miller Trailhead — or like I was doing today — the long route from Wendy Drive.
Although I usually climb the peak, two other options are worthwhile: the loop around the ocean-facing side of Mugu Peak and
the loop around La Jolla Valley.
The wildflowers along the Mugu Peak Trail and La Jolla Loop Trail were fantastic. California poppies were plentiful on the south-facing slopes. The vibrance of the bright orange poppies could not have been better accentuated than by purple lupine. Yellow bush sunflower, royal blue phacelia, and rich red paintbrush also decorated the trail.
I followed my usual route on the way back to Wendy — returning to the Hub, descending Hell Hill, retracing my steps in Wood Canyon, then following the Two Foxes single-track trail north to a short connector to Sycamore Canyon Road. This is near the Danielson Multi-Use Area. Once on Sycamore Canyon Road, the route back was the same as last week — up 1.8 miles of paved road and then onto the Upper Sycamore Trail. After that, up Danielson Road and across Satwiwa to the Wendy Drive trailhead.
The morning was beautiful and sunny. It hadn’t rained for two days, and except for a few contrails, the sky was nearly cloudless.
Earlier in the morning, I’d climbed the Western Ridge of Boney Mountain, then worked my way over Tri Peaks to the Backbone Trail. I’d been on cruise control running down the Chamberlain/Backbone Trail, enjoying the pleasant weather and wide-ranging views.
Passing a gap in the ridge, I was surprised to see a person on the hillside, a few yards below the trail. It was an odd place to be.
The person was partially hidden by grass and brush, and all I could see was their head and shoulders. They were wearing an odd helmet and were busy working on something that looked like a pack. I didn’t see a mountain bike.
None of it made sense. Was it someone doing the Backbone Trail? Had they slept there overnight? What was with the helmet? Reaching the end of the Chamberlain Trail, I turned right on the Old Boney Trail and continued the descent toward Blue Canyon.
Partway down, I heard the clap-clap-clap of helicopter blades approaching the canyon, and that’s when it all fell into place. The mysterious person along the Chamberlain Trail was a SAR crew member.
The helicopter was yellow, probably from the Ventura County Sheriff Search and Rescue Aviation/Medical Team. I’ve seen them in the area a number of times doing exercises.
This wasn’t the first time I’d seen something strange from the Chamberlain Trail. A few years ago, I’d noticed an odd-looking object below the Chamberlain and Old Boney Trails junction. It turned out to be a rescue manikin strapped onto a litter. Practice makes perfect, and exercises help ensure the safety and success of demanding SAR operations.
Farther down the Backbone Trail, there was a striking display of California poppies and bush sunflowers on the hillside above the junction of the Backbone and Old Boney Trails. After photographing the poppies, I returned to the Backbone Trail and entered Blue Canyon. To this point, I’d managed to keep my shoes and socks dry. But that was going to end.
I’d done a similar route in January, partly to see the condition of the Chamberlain, Blue Canyon, and Upper Sycamore Trails. That was the case again today. In the two months since the January run, nearby Circle X has recorded over 13 inches of rain. Not surprisingly, that has resulted in more water in the streams, more wildflowers along the trails, and a bit more eroded and rougher trails.
I like splashing through streams as much as anyone does, but today I wanted to try and keep my shoes and socks dry. This Winter that’s been surprisingly hard to do.
Weekdays, I often run from the Victory trailhead at Ahmanson Ranch over to Las Virgenes Canyon and back. But it had rained in the Los Angeles area for four days straight. There was just no question that Ahmanson was going to be wet and muddy, and Las Virgenes Creek would be too wide to jump. I’d have to wade the creek crossings — again.
That’s why this afternoon, I was doing an out-and-back run on Rocky Peak Road from the 118 Frwy trailhead. As a result of the area’s sandstone geology, Rocky Peak Road is usually a pretty good place to run during periods of wet weather. For one thing, there are no creeks to cross. Plus, the rocky and sandy road doesn’t have many areas of “glob on your shoes” mud. It also has excellent views of the San Fernando and Simi Valleys and surrounding mountains.
My turnaround point today was the top of the Chumash Trail, which is a little less than four miles from the Rocky Peak trailhead. I sometimes continue past the Chumash Trail another mile to Fossil Point.
Today, there was one short, muddy stretch that could be mostly avoided and a few large mud puddles I could walk around. At the end of the run I didn’t have to switch shoes to drive home!
