Out and Back Trail Run from the Top of Reseda to Parker Mesa Overlook

The view from Parker Mesa Overlook was the uniform gray of the inside of a cloud. I was about 30 minutes too early, and the low clouds hadn’t cleared. The Pacific Ocean was out there somewhere.

Even so, the run from the Top of Reseda to the Overlook had been excellent. The hills and canyons were painted in a muted palette of sun and shadow. Purple-pink prickly phlox brightened the roadside, and the “Beech-nut Gum” scent of Bigpod Ceoanthus filled the air.

Fire Road #30, Eagle Springs Fire Road, and East Topanga Fire Road had all been cleared of the sluffs and slides that resulted from January’s rainstorms. Overnight, there had been a little drizzle, but the fire roads hadn’t been muddy at all.

Rather than just retracing my steps, on the way back to the Top of Reseda I opted to do the Musch and Garapito Trails. I had run the Garapito Trail in mid-January but hadn’t been on the Musch Trail since the January deluge.

The Trippet Ranch parking lot had been packed, and several groups appeared to be on their way to Eagle Rock via the Musch Trail. Overall, the trail weathered the storms reasonably well, but one badly eroded section and a couple other spots will need some work.

While it still had some issues, use of the Garapito Trail had moderated its condition since the last time I was on it. Some brush that had blocked the trail had been removed, and paths were evolving through the collapsed sections of trail. However, some extra care was still required in some spots.

The Bent Arrow Trail was closed, necessitating a return to dirt Mulholland on Fire Road #30, following the same route as had been used at the beginning of the run.

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.

Downtown Los Angeles (USC) Already at 94% of Normal Annual Rainfall

La Ninas are fickle beasts, and particularly in a time of climate change, the existence of La Nina conditions in the equatorial Pacific is no guarantee of a dry rain season in Southern California.

According to preliminary rainfall data, from December 1, 2022, to January 16, 2023, Downtown Los Angeles (USC) recorded 11.01 inches of rain. This was 77% of the normal rainfall for an entire year.

This brings the Rain Year total precipitation for Los Angeles up to 13.38 inches — the sixth wettest for the date going back to 1877 — and 94% of the normal ANNUAL rainfall.

Ahmanson Ranch Out and Back Trail Run from the Victory Trailhead to the Las Virgenes Trailhead Via Lasky Mesa

The direct out and back trail run from the Victory Trailhead at Ahmanson Ranch through East Las Virgenes Canyon to the Upper Las Virgenes Canyon Trailhead is about 3 miles each way.

This variation bypasses most of East Las Virgenes Canyon. It climbs up to Lasky Mesa and then descends “The Beast” to East Las Virgenes Canyon about 0.4 mile before it joins the fire road in Upper Las Virgenes Canyon. This fire road can be followed south to the Upper Las Virgenes Canyon Trailhead, the turnaround point.

Depending on the exact route, the trail run totals about 7.5 miles, with about 825 feet of cumulative elevation gain. The Beast is the longest continuous hill and is about 0.8 mile in length.

Here is an interactive, 3D terrain view of my out and back trail run from the Victory Trailhead at Ahmanson Ranch to the Las Virgenes Trailhead via Lasky Mesa. The direct route through East Las Virgenes Canyon is also shown. The map can be zoomed, tilted, rotated, and panned using the navigation control on the right. Track and placename locations are approximate and subject to errors. Poor weather and other conditions may make this route unsuitable for this activity.

When it rains a lot, sections of East Las Virgenes Canyon can get really muddy. This route avoids the worst of the gooey, stick-on-your-shoes mud.

Update January 17, 2023. With the additional rainfall this January the “best” route up to Lasky Mesa is on the dirt road. The single track is wet and muddy in spots.  The lower half of the Beast is eroded and somewhat muddy. I have a pair of shoes that I use in the muck and wet. They haven’t dried out for weeks.
