Track of a Big Rattlesnake in Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch)

Track of a Big Rattlesnake in Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch)

This is the largest Southern Pacific Rattlesnake track I’ve seen in 20+ years of running at Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch) — or anywhere else.

The rattlesnake that made this track looks like it was larger than this Southern Pacific Rattlesnake, photographed at Ahmanson Ranch in April 2010.

Twenty-Plus Years Running the Strawberry Peak Circuit

The repeated cries of a falcon called from high on the north face of Strawberry Peak. Along the sandy trail, lupine, paintbrush, penstemon and yarrow bloomed in a profusion of blues, reds, and yellows. Tracks from running shoes, bikes, boots, and a black bear proclaimed the trail to be truly multi-use.

I sighed and took it all in. I’d been doing this classic 16-mile route for more than 20 years. A favorite of mountain bikers and runners alike, the loop can be broken down into the following segments.

Josephine Fire Road Climb

From the Clear Creek Trailhead, Josephine Fire Road climbs about 1250′ over 2.5 miles to a divide connecting Josephine and Strawberry Peaks. At the junction, the route turns right (east) onto a trail along the divide that goes to Josephine Saddle. A left (west) turn goes to Josephine Peak.

On the way up from Clear Creek, the switchbacks on the fire road look intimidating, but the climb goes relatively quickly. There are good views of Strawberry Peak along the way. In the Spring and early Summer, the bright yellow flowers of invasive Spanish broom line the road.

An out-and-back ascent of Josephine Peak from the junction adds about three miles to the loop.

There is a Remote Automated Weather Station (RAWS) at Clear Creek Station. The “2.0m Temperature” is more or less the temperature in the shade and the “Fuel Temperature” is a good indicator of the temperature in the sun.

The route joins the Colby Canyon Trail at Josephine Saddle. A large cistern is found here. Just past the saddle, the climber’s trail to Strawberry Peak branches off the main trail and goes up the ridge. The Colby Canyon Trail contours along the left (northwest) side of the ridge and traverses a steep slide area. After that, it works around the shoulder of Strawberry, then turns east and descends, winding in and out of the small canyons on the northwest and north slopes of Strawberry.

In the Spring and Summer colorful patches of lupine, paintbrush, and other wildflowers are found on this stretch of trail. Long-limbed big cone Douglas-firs grow on these cooler north-facing slopes.

The bare trunks of trees burned in the 2009 Station Fire are mixed in with surviving trees. Today, I was surprised to find another reminder of the Station Fire — poodle-dog bush. The plant can cause a poison oak-like rash and was much more common following the 2009 Station Fire.

On this stretch, the large rock face on the north side of Strawberry Peak comes into view, and shortly after, the trail passes a huge boulder. The flattish area that follows is Strawberry Protreo. The “meadow” reminds me of lower elevation areas of the Southern and East Side Sierra.

Several climbing routes have been done on Strawberry’s formidable north face. The consensus seems to be that the rock quality is poor and the risk high.

Beyond Strawberry Protreo, the trail descends along the margin of a moraine-like landslide. Then it turns south, reaching a flat, sandy area just before the Colby Canyon Trail – Strawberry Trail junction. I’ve often seen bear tracks on this stretch of trail. The loop takes the right fork onto the Strawberry Trail and climbs to Lawlor Saddle.

The Strawberry Trail gains about 750′ over two miles on its way to Lawlor Saddle. As the post “Trail Games” mentions, this stretch will tell you a lot about how your day is going. It dips in and out of side canyons, passing Strawberry Spring along the way. Today, Strawberry Spring was running, but the spring was dry during our recent drought.  It is generally not a dependable water source.

The 2.5 miles to Red Box are enjoyable single-track trail. Most of it is flat or downhill. On the weekend, numerous hikers are on the trail, heading up to climb Strawberry Peak. It is by far the busiest trail on the loop.

There’s a water faucet at Red Box at the Haramokngna American Indian Cultural Center which generally (but not always) has water.

The 4.4 miles down to Switzer’s include some fast-paced stretches and some of the most technical sections of the loop. It is popular with mountain bikers and V-ed and rutted in places. At one point, the trail drops down to the stream (if it’s running) and crosses the creek twice.

Among the many wildflowers found along this trail is crimson-spotted rock rose.

As the trail nears Switzer’s, derelict nature signs are seen along the trail, which the Forest Service apparently can’t afford to repair or remove.

Nature’s Canteen Trail to Clear Creek

The Nature’s Canteen Trail is roughly half a mile long and connects Switzer’s to Clear Creek. It starts a third of a mile up the steep access road between Switzer’s and Angeles Crest Highway. The trail is sometimes overgrown.

Strawberry Peak Variation

There is a more adventurous variation of the Strawberry Peak Circuit that goes over the top of Strawberry Peak instead of around it. This variation requires good route-finding and rock-climbing skills.

This interactive, 3-D terrain view shows the classic Strawberry Peak Circuit and the Strawberry Summit Loop variation.

California Vole Foraging in Upper Las Virgenes Canyon Open Space Preserve (Video)

Running south in upper Las Virgenes Canyon, I’d passed the connector to Cheeseboro Canyon and was nearing Las Virgenes Creek. Before reaching the creek, I turned left off the main road onto a path that has a log bridge across the creek.

As I stepped onto the berm at the edge of the road, I caught a glimpse of something small and furry moving at my feet. I stopped and stepped back.

That’s when the vole poked its head from a burrow. I could almost see it squinting as it assessed whether or not I was a threat. Deciding to continue foraging, it emerged from the hole as far as it dared, and worked to free a small clump of grass at the margin of the burrow. Mission accomplished, in a flash of fur it returned to its burrow.

Ahmanson Ranch and Upper Las Virgenes Creek After Six Days of Rain

After January 2023’s torrential rains and Hurricane/Tropical Storm Hilary’s drenching in August, here we are again, experiencing record rainfall.

Over the first six days of February 2024, Downtown Los Angeles recorded 10.2 inches of rain. That’s almost three-quarters of L.A.’s normal ANNUAL rainfall in just a few days and the wettest start to February on record! Some stations in the Santa Monica and San Gabriel Mountains recorded even more — over 13 inches in some locations!

How much did it rain at Ahmanson Ranch (Upper Las Virgenes Canyon Open Space Preserve)? Unfortunately the Remote Automated Weather Station (RAWS) on a hill between Upper Las Virgenes Canyon and Cheeseboro Canyon hasn’t been accurately measuring precipitation. A citizen weather station (KCAWOODL130) near the Victory Trailhead at Ahmanson Ranch recorded over 11 inches from February 1 – 6. Another station near Cheeseboro Road in Agoura (KCAAGOUR41) recorded over 9 inches.

Whatever the amount, it was a lot. Here is a short video, from a run at Ahmanson Ranch on February 7, 2024, to check out the conditions and creeks.

As I write this, more wet weather is forecast to affect the Los Angeles area, beginning sometime over the weekend of February 17-18. We’ll see!

Update Friday, February 16, 2024.  Latest forecast for Los Angeles area suggest the rain may hold off until Sunday night or Monday.

Three Bighorn Sheep, a Solar Eclipse, and a New Peak

Had they not dislodged some rocks, I doubt I would have seen the three bighorn sheep in the photo above.  They are easier to see in this zoomed-in photo of the sheep descending the rocky slopes just below Windy Gap (7,588′) in the San Gabriel Mountains. They crossed a brush-covered rib and disappeared from view.

A few minutes after seeing the sheep, I reached Windy Gap and stopped to put my arm sleeves away. It had been cool at the trailhead — about 40 degrees — but the temperature had warmed as I worked up the trail. As its name suggests, the wind can be fierce at Windy Gap, but this morning there was almost no wind, foretelling nearly ideal weather for today’s adventure.

Windy Gap was still in shade, and the sun was just peeking over the ridge to the east. You couldn’t tell, but the eclipse had already begun. The eclipse would be nearly total in parts of Oregon, Nevada, Utah, New Mexico, and Texas. In the Los Angeles area, the moon would obscure more than 70% of the sun’s disc.

From Windy Gap, I headed east on the Pacific Crest Trail toward Mt. Hawkins. From time to time, I would stop and check the progress of the eclipse using eclipse sunglasses. In sunny areas, I looked for lensed images of the sun in the shadows of trees but didn’t see any. Having needles instead of leaves, conifers don’t produce the myriad images of the eclipsed sun seen under trees with leaves.

A few minutes before the eclipse reached maximum, I took this photo of the eclipse with my iPhone, using eclipse glasses as a filter.

With nearly three-quarters of the sun obscured, the light from the sun had become enfeebled. The feeling was more than that of a cloud passing in front of the sun. I stopped and listened… to nothing. It was eerily quiet. No birds called or sang, and only chill zephyrs of wind wafted about the area. Somehow, the sun was broken.

As the eclipse slowly waned, I continued east in the corrupt light, past Mt. Hawkins and Throop Peak, to the PCT’s junction with the Dawson Saddle Trail. In what seemed fitting for the day, instead of continuing to Baden-Powell, I turned left and headed down the trail toward Angeles Crest Highway (Highway 2).

Why? Angeles Crest Highway was closed from Red Box to Vincent Gap, transforming Dawson Saddle into one of the more isolated areas of the Angeles National Forest. I hadn’t been on the Dawson Saddle Trail in years, and with Highway 2 closed, it would be a quirky way to climb Mt. Lewis. Instead of having one of the shortest approaches in the San Gabriels — a few feet from the CalTrans shed at Dawson Saddle — it would involve a trail run of nearly eight miles just to get to the base of the peak.

The eclipse was nearly over when I reached the bottom of the Dawson Saddle Trail on Highway 2. From the trailhead, I ran up an empty Angeles Crest Highway a short distance to Dawson Saddle. Mt. Lewis’ south ridge was accessed from here.

Only about a half-mile long, the south ridge isn’t technical, but the first third is steep and rocky. The elevation gain from the saddle to the summit is about 500′. Offset from the crest of the San Gabriels, the flat summit of Mt. Lewis has unique views of the crest extending from Mt. Baden-Powell to Mt. Islip and beyond.

After a few minutes enjoying the summit, I turned southward and began working my way back down to Angeles Crest Highway, up to the PCT, over to Windy Gap, and back down to the trailhead in the Crystal Lake Recreational Area.

Here are a few photos taken along the way.

Wonderful Wildflowers, a Seasonal Bridge, and a Cranky Rattlesnake on the Bulldog Loop

Update May 5, 2023. Did a run this afternoon in Malibu Creek State Park and the seasonal bridge across Malibu Creek on the Crags Road Trail is back in place!

As I approached the M*A*S*H site, I could see some people taking photos. I stopped to say hi, and without skipping a beat, one of them asked, “Did you wade across the creek?”

He was asking about the creek crossing where Crags Road crosses Malibu Creek upstream of Century Lake and east of the M*A*S*H site.

There’s a substantial log spanning the creek at the moment, and I wanted to answer that I danced across it with my eyes closed. But instead, I explained that I decided to wade — and for sure keep my phone dry — rather than take a chance of falling uncontrolled into three feet of water, ker-splash.

Speaking of which, this morning, I talked to a mountain biker who saw the bridge pulled off to the side of the creek before any flooding had occurred and thought it may have been hauled away. Good news! According to the Malibu Creek Docents, the bridge is seasonal and was designed to be portable. It was removed and stored before this Winter’s rain. It is expected to be reinstalled when the threat of flooding is over — which should be soon.

After crossing Malibu Creek and before continuing to the M*A*S*H site, I took a quick detour on the Forest Trail. Bordered by Century Lake on one side, and steep, rocky slopes on the other, the Forest Trail has a character all its own. It’s a wonderful place to observe, reflect, and enjoy nature. It’s also home to several coast redwoods. Unfortunately, less than half the trees originally growing along the trail survived the 2011-2015 drought. This morning, a redwood that died several years ago had fallen and was partially blocking the trail near its halfway point.

As has been the case in most of Southern California this Spring, the wildflowers on this run were spectacular. Canyon sunflower was particularly prevalent, with many thousands of the bright-yellow blossoms covering the hillsides burned in the 2018 Woolsey Fire.

Also exciting was my first rattlesnake encounter of 2023. I was running down Castro Peak Mtwy Fire Road from the Bulldog “T” when I saw something in the road that looked like a partially exposed root. As I neared, I could see it was a very dark — almost black — Southern Pacific Rattlesnake.

The snake was stretched out straight on the road, basking in the sun. As I approached, it did move, and it did not rattle. Usually, snakes in this state are pretty docile, and I can cautiously walk a few feet behind them. Yikes! This one was super-aggressive. In the blink of an eye, it turned and moved toward me, doubling back on itself. I jumped a mile! It coiled but still did not rattle! It must have recently emerged from its Winter hideaway.

Here are a few photos (primarily wildflowers) taken on the Bulldog Loop.
