Backbone Trail Mystery

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.

Rainy Weather Running on Rocky Peak Road

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!

Snow-Covered San Gabriel Mountains From Lasky Mesa

It had rained another inch overnight, and my shoes were soaked from the wet grass along the trail. Seeking some relief from the 20 mph northwest wind, I descended a single-track trail to an old paved road east of the ranch house on Lasky Mesa.

Motivated more by staying out of the wind than anything else, I did two sets of hill repeats on different sections of the road. Then, on tired legs, I jogged up to Lasky Mesa and was greeted by an Arctic blast. The temperature had dropped to the mid-40s, and the wind was blowing a steady 20 mph, gusting to around 30 mph. I didn’t need a wind chill chart to tell me the effective temperature was in the 30s.

I was so focused on dealing with the cold I wasn’t paying much attention to my surroundings. Deciding to do one more hill, I rounded a corner, and the brilliantly sunlit, snow-covered San Gabriel Mountains came into full view. It was just jaw-dropping!

Here is a wider view of most of the Front Range of the San Gabriels, white with snow.

More Malibu Creek Flooding (January 2023)

April 26, 2023 Update. As it turns out, the shiny, new bridge on the Crags Road Trail that made it easy to cross Malibu Creek was not washed away! According to the Malibu Creek Docents, the bridge was designed to be portable, and 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.

I was just a couple of miles into an extended version of the Bulldog Loop. The temperature was in the mid-30s, and once again, I was having to cross Malibu Creek on a makeshift bridge of wobbly limbs and debris.

The flood was the result of a series of three increasingly wet storms between December 30 and January 10. During that period, the Malibu Canyon RAWS recorded about 13 inches of rain. In the last storm of the series, 6 inches of rain was recorded in about 33 hours.

The flooding along the Crags Road Trail from the Forest Trail junction to the M*A*S*H site was similar to the February 2017 and December 2021 events. In the January 2023 event, more debris was deposited on the trail, and sections of the trail were obliterated. That stretch of trail is popular, and a new use trail is already taking shape.

Rainfall and runoff were even higher in Santa Barbara and Ventura Counties. The Rose Valley RAWS recorded over 22 inches of rain for the three storms. According to preliminary streamflow data, the Ventura River Near Ventura reached a new record stage height of 25.42 feet on January 9. The Sespe Creek Near Fillmore gage malfunctioned at the peak flow but reached at least 20.38 feet.

Popular Trails in Topanga State Park Damaged by Winter Storms

Several popular trails and fire roads in Topanga State Park have been damaged by the cumulative effects of Winter 2022-2023 rainstorms.

Since December 1, 2022, the Topanga Remote Automated Weather Station (RAWS) has recorded nearly 16 inches of rain. The most rainfall occurred January 9-10, when about 5.4 inches was measured.

On Sunday, January 15, I did an exploratory trail run from the Top of Reseda that took me through some popular areas of the Park. This included Fire Road #30, the Hub, Temescal Peak, Temescal Lookout, Temescal Ridge Fire Road, Eagle Springs Fire Road, Eagle Rock Fire Road, the Garapito Trail, and the Bent Arrow Trail.

There were numerous mudslides on the fire roads. The larger slides were on Fire Road #30 below the Hub and Temescal Ridge Fire Road between the Backbone Trail junction and Temescal Lookout. There was also significant roadbed and shoulder erosion in places. At the time, all were passable on foot.

The trails were a different matter. Unfortunately, much of the repair work done on the Bent Arrow Trail following last year’s rain was damaged or destroyed.

The Garapito Trail was blocked in two places on the upper part of the trail. One problem was from a sluff of soil and brush sliding onto the trail. The other was from the collapse of a section of trail. There were additional sluffs, limbs, and washouts on the trail that were passable at the time.

Update February 5, 2023.  The Bent Arrow Trail is closed. Fire Road #30, Eagle Springs Fire Road, and East Topanga Fire Road to Parker Mesa Overlook had all been cleared. The Musch Trail was eroded in spots but OK. Use of the Garapito Trail has moderated its condition. Some brush had been cleared and paths have evolved through the sections of collapsed trail. Extra care is required in some spots.

Here are a few photos taken along the way.

Other trails and fire roads in Topanga State Park likely had similar impacts. I would expect, like last year, sections of the Santa Ynez Trail lower in the canyon to be washed out.
