Southern Pacific rattlesnake at the Victory Trailhead of Upper Las Virgenes Canyon Open Space Preserve.

I pressed the START/STOP button on my Garmin watch and started to walk over to the horse/hiker entrance at the Victory Trailhead of Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch). This “end of an Ahmanson run” routine is something that I repeat around 150 times a year. It’s so routine, it’s rote. I’m not thinking about rocks or ruts, or how far I have to go. It’s a time I can relax and reflect on the run, the weather, or whatever.

Continuing toward the trailhead entry, I pulled the water bottle from my pack. Lifting my head to take a drink, and still on auto, I began to step over the first of two large wooden beams forming the entrance.

Some primitive, protective mechanism recognized the threat before I did, and I stopped mid-stride. Then it registered — a sizable Southern Pacific rattlesnake was undulating through the boxed-in area between the two beams of the entryway.

Moving quickly through the entry and into the grass, the snake barely reacted to me. With single-minded resolution, it continued on a beeline toward the brushy area near the trailhead. A single shake of its rattle was all the bother I was worth. Here’s a short video of the Southern Pacific rattlesnake at the Ahmanson Ranch trailhead.

Surprisingly, this was the first rattlesnake I’ve seen this year at Upper Las Virgenes Canyon Open Space Preserve . I’ve seen numerous gopher snakes, a couple of California kingsnakes, a California whipsnake, and the tracks of many rattlesnakes, but no actual rattlesnakes. Others have described various rattlesnake encounters at Ahmanson — one friend saw three on one ride!

Note: Most of these snakes were old enough to have survived the November 8, 2018, Woolsey Fire.

An Upper-Level Low Sunrise, Shower, and Sunset

first published & last updated

Sunset in West Hills, CA, associated with an upper-level low off the coast of Southern California.

It was about 15 minutes before sunrise when I started my run from the trailhead at the “Top of Reseda.” After running up to Mulholland and partway down Fire Road #30, I could see a batch of tropical-looking clouds to the southeast. These were associated with a cutoff upper-level low that had formed off the coast of Southern California on Halloween.

The behavior of cutoff upper-level lows is difficult to forecast. They are usually separated from the general west to east flow and typically wobble around like a spinning top. A cutoff low can remain off the coast for several days or more. Just where they wobble can dramatically impact the weather. So far this morning, the only effect of this weak low had been to embellish the sunrise with a few clouds, but such lows can be capricious, and this one was no exception.

My first stop was going to be Temescal Peak, and I picked up the pace a bit, curious to see how the clouds and sunrise might look from that viewpoint. Temescal Peak is just off the Backbone Trail, near its junction with Temescal Ridge Fire Road. On a clear day this tiny peak affords an exceptional 360-degree view that can include Mt. Baldy, San Gorgonio Mountain, San Jacinto Peak, Mt. Pinos, Hines Peak, and other area landmarks.

Turning left at the Hub, it didn’t take long to get to Temescal Peak. Westward from the peak, a veil of smoke could be seen in the vicinity of the Maria Fire. Nearby, some of the canyons in the area of the Getty Fire were filled with a smoky haze. In the distance, a few mercurial clouds were scattered across the eastern sky.

At the time, I couldn’t tell if the clouds were approaching or receding, developing or dissipating. Returning to the Hub, I turned left on Eagle Springs Fire Road and began the descent toward Trippet Ranch. On the way, it became clear the clouds were headed my way. By the time I’d run to Trippet Ranch and up to the top of the Musch Trail, the band of clouds covered much of the eastern sky.  Virga streamed from the bases of some of the clouds, and  I wondered if a few rogue drops might be reaching the ground.

Over the remainder of the run — past Eagle Rock and through Garapito Canyon — the clouds continued to move overhead. A few drops of rain found me near the end of the run, but the most pleasant surprise occurred on the drive home, when showers dampened the  streets of the western San Fernando Valley.

There had been no rain in the Los Angeles area this October, and the showers reminded me of the erratic nature of Autumn precipitation in Los Angeles. Even though “normal” rainfall in October at Downtown Los Angeles (USC) is 0.66 inch, no one familiar with L.A. weather is surprised when October is dry. Over 143 years, Downtown Los Angeles has recorded no October rainfall 26 times, 0.10 inch or less 54 times, and 0.25 inch or less 74 times.

The upper-level low continued to influence the day’s weather, and while the low remained mostly offshore and didn’t generate any more showers in the West Valley, it did produce a colorful sunset!

Visualizing Trail Runs and Other KML Data Using Cesium 3D High Resolution Terrain

Cesium ion 3D view of San Gorgonio Mountain

Google discontinued its Google Earth API/Plugin in January 2017. That technology was used on PhotographyontheRun.com for 3D visualizations of trail runs, fire data, and other data.

I’ve been looking at alternatives since then, and have recently implemented an interactive viewer using the CesiumJS and Cesium ion components of the Cesium 3D Geospatial Platform. No browser add-on or plug-in is required. The viewer uses the Cesium World Terrain high-resolution global terrain tileset, with resolutions to 0.5 meter. The West Coast of the US is one of the areas covered by this resolution.

Following are example 3D visualizations of some of my recent runs. The views are interactive and can be zoomed, tilted, rotated and panned. Click/tap the “?” in the upper right corner for help manipulating the scene. Mileages and elevation gains/losses are approximate.

San Gorgonio Mountain Trail Run (21 mi, 4700′ gain/loss)

The initial view is of San Gorgonio Mountain from the northeast, showing the trail to the summit and the Sky High Trail. The large cirque held one of several glaciers on San Gorgonio Mountain. The GPS track is from a run in September.

San Gorgonio Mountain Trail Run and Lake Fire Burn Area

Another view of San Gorgonio Mountain with the 2015 Lake Fire burn area added. The initial view is from the northwest. The GPS track is from my run in September.

Bulldog Loop Variation (17 mi, 3250′ gain/loss)

The initial view of this popular loop is from the northeast. This variation starts/ends at the Cistern Trailhead on Mulholland Hwy. The GPS track is from a run of the loop in September.

Three Points Loop Around Mt. Waterman (20 mi, 4000′ gain/loss)

The initial view is from the Buckhorn (east) side of the loop. The loop includes a segment of the PCT in Cooper Canyon. The GPS track is from a run in October.

Top of Reseda to Parker Mesa Overlook (18.5 mi, 3100′ gain/loss)

The initial view is from the northeast, on the Valley side of the route. The Musch, Garapito and Bent Arrow Trails were done on the way back from Parker Mesa. The GPS track is from a run in October.

California Fuchsia Along East Las Virgenes Canyon Road

California fuchsia in Upper Las Virgenes Canyon Open Space Preserve

If the wildflower is red, the season is Fall, and you are in Southern California, the flower is probably California fuchsia. You might also find there is a hummingbird feeding on the “hummingbird trumpets,” or hovering nearby, watching over its flowers.

As a result of the wet 2018-19 rain season, and somewhat cooler than normal summer, California fuchsia is especially abundant this Fall, with some exceptional displays along local trails.

I’ve added California fuchsia, and a few other flowers that are blooming this Fall, to my Weekday Wildflowers slideshow. These are wildflowers photographed this year on weekday runs from the Victory Trailhead of Upper Las Virgenes Canyon Open Space Preserve.

What? My iPhone (And Camera) Have Been Disabled?

first published & last updated

iPhone is disabled

There aren’t many things more frustrating to a photographer than seeing a potentially good photo and discovering your camera is unusable.

I almost always run with a camera. As part of my routine before a run, I swap out the camera battery for one that is fully charged, check the flashcard, check the lens, check the camera settings, and take a test photo. This helps ensure the camera will be ready to go when needed.

Often I’ll run with a camera and phone, but sometimes I’ll just take the phone. Three or four times over the past two years I’ve been running, stopped to take a photo, and discovered my iPhone X has been disabled. How does that happen?

From what I can determine, there is only one way you can be locked out of your iPhone — by entering an incorrect passcode too many times.

You might reasonably ask, “Why were you having so much trouble entering your passcode?” The thing is, I wasn’t entering any passcodes. My phone was becoming disabled while in a pocket of my running pack.

At first, I thought the phone’s “Raise to Wake” feature was the culprit, but disabling that setting didn’t fix the problem.

For a while, I overlooked the “Tap to Wake” setting, thinking that a tap would require human interaction. But it doesn’t. An iPhone X sitting in a pocket that is moist from sweat can interact with the fabric touching the screen to wake the phone up, swipe up, and then enter passcode numbers.

Now, when I run with my phone, in addition to having “Raise to Wake” disabled, I temporarily disable “Tap to Wake.” Since doing this, my phone — and camera — haven’t been inadvertently disabled.

The easiest way to locate these settings is to enter “wake” in the Search box at the top of the Settings screen and then tap on either “Raise to Wake” or “Tap to Wake.”

For detailed info about what happens when you repeatedly enter incorrect passcodes on your iPhone, see Encryption and Data Protection > Passcodes in the Apple iOS Security guide.

An Out-of-the-Way Trail, Two Peaks, a Wheelbarrow, and Washington’s Monument

Forsee Creek canyon from the John's Meadow Trail in the San Gorgonio Wilderness.

Wow, what a fantastic trail, canyon, and morning!

The view above is from the John’s Meadow Trail, a circuitous trail that winds its way through a less-traveled part of the San Gorgonio Wilderness.

The prominent canyon in the photo is home to Forsee Creek. During the last ice age, it held one of San Gorgonio’s small glaciers. I’d just crossed the Forsee Creek a few minutes before, and in a few hours would run past its source high on the crest — Trail Fork Springs.

The peak at the head of the canyon is East San Bernardino Peak (10,691′). Its summit marks the crest of the divide and the location of the San Bernardino Peak Divide Trail. That’s where I was headed, but the path would be anything but direct.

From the Forsee Creek crossing at 7270′, the John’s Meadow Trail climbs about 1000′ in 2.3 miles to join the Divide Trail at “wheelbarrow junction,” about 5 miles west of East San Bernardino Peak. From that point I worked up the popular and scenic Divide Trail, visiting Limber Pine Bench (9330′), Washington Monument (10,290′), and San Bernardino Peak (10,649′) along the way to East San Bernardino Peak.

Using this roundabout — but very scenic — route, it took me about the same time to reach San Bernardino Peak from the Forsee Creek Trailhead as it does to do San Gorgonio Mountain from the South Fork Trailhead. From San Bernardino Peak it’s a little less than a mile to East San Bernardino Peak and from there only about 0.75 mile to the lateral to Trail Fork Springs.

From the westernmost Trail Fork Springs junction with the Divide Trail the theme was downhill, downhill, and more downhill — about 3800′ of downhill over 6.7 miles.

The running on the Forsee Creek Trail was generally very good. I was glad I did the loop counterclockwise. The John’s Meadow Trail and its extension are enjoyably primitive — they appear to be “use” trails that have evolved over time. On the other hand, the Forsee Creek Trail is a constructed trail. It was designed as a pack trail, so is generally well-behaved. Great for going down, but a long haul up with a heavy pack!

Here are a few photos taken along the way, and here is an interactive Cesium ion view of the GPS trace of my route. The 3D view can be zoomed, tilted and panned.

Note: Water is generally more reliable and accessible on the John’s Meadow Trail than on the Forsee Creek Trail. Trail Fork Springs and Jackstraw Springs are seasonal water sources that may not have water. Check with the Mill Creek Ranger Station for the current conditions and more info.
