The clouds were associated with a front that stalled to the north of Los Angeles, resulting in some surprising and substantial rainfall totals in Santa Barbara and San Luis Obispo Counties. No measurable rain was reported in Los Angeles County by the NWS.
From an early morning run at Ahmanson Ranch (Upper Las Virgenes Canyon Open Space Preserve) on September 20th.
After weeks of dealing with one heatwave after another it was a strange sensation. I was cold. I had on an extra shirt and sleeves, but the slopes of Mt. Islip were deep in shadow and the wind was gusting to 20 mph. The thermometer on my pack read 41 degrees, but the “feels like” temperature had to be in the 30s.
I was in the first mile of an out and back trail run from Islip Saddle to Mt. Baden-Powell. A San Gabriels classic, the route gains (and loses) about 3800′ over 16.5 miles on the PCT.
This morning I was doing the basic out and back, but Mt. Hawkins, Throop Peak and Mt. Burnham are easy peaks that can done along the way. Mt Islip is is a bit more of a detour, but can also be added to the route.
It’s also possible to start the out and back at the Windy Gap Trailhead (5836′) in the Crystal Lake Recreation Area. The distance to Baden-Powell is about the same, but the lower trailhead adds about 800′ of gain.
As I chugged up one of the initial steep sections, I thought about what it must have been like for this year’s participants in the AC100. This year, because the AC100 was an out and back from Wrightwood to Shortcut Saddle, runners got to do this tough segment after running more than 75 miles!
Update on August 17, 2022. As of today, my West Hills weather station has recorded a high of 100 degrees or higher for 12 consecutive days.
It was another triple-digit Sunday. Once again the high in the west San Fernando Valley was forecast to hit one-hundred and something. I’d hope to beat most of the heat by getting an early start and running where it wouldn’t be quite so hot.
I hadn’t been able to get out to Stoney Point Saturday morning, so was looking to do a little easy climbing as part of my Sunday run. I was considering three options: Topanga Lookout Ridge, Strawberry Peak, and Boney Mountain.
While none of the three are difficult by rock climbing standards, all require the use of handholds and footholds, good route-finding skills, and good judgment. It is entirely possible to fall on any of them.
The Topanga Lookout Ridge loop is about 8.5 miles long with 2000′ of gain/loss. There are a few short climbing segments on the crest of the ridge that can be accessed from the use trail.
The basic loop up the Western Ridge of Boney Mountain and over Tri Peaks to the Backbone Trail and back to Wendy Drive is about 15.5 miles long with 3400′ of gain/loss. It is longer and more difficult than the Topanga Lookout Ridge loop.
The loop over the top of Strawberry Peak from the Colby Canyon Trailhead is about 12 miles long with 3100′ of gain/loss. There is some class 2/3 climbing on the west side of Strawberry, and it is essential to stay on route. There have been a number of rescues of those attempting to climb the peak.
It was a few minutes past six when I pushed the start button on my Garmin and jogged down the hill from the trailhead at Wendy Drive. I’d run about a half-mile when I heard another runner behind me. We chatted for a couple minutes and I learned he was preparing to do the Wonderland Trail around Rainier and then the Bear 100.
We were both going to the same area, but by different routes. I was climbing Boney Mountain’s Western Ridge and then working over to the Backbone Trail. He was doing an out and back to Sandstone Peak via Upper Sycamore, Sycamore Canyon, and the Backbone Trail. We would run into each other again at the Danielson Multi-Use Area on the way back to Wendy Drive.
As always, the climb up the Western Ridge (Mountaineer’s Route) was enjoyable. The rock climber in me always wants to check out potential lines, but this morning there wasn’t much time for that. The longer it took to get up Boney, the hotter it was going to be later in the run!
The temperature was already in the eighties when I reached the Backbone Trail. Before the fires and floods of past decade, the run down the Chamberlain segment of the Backbone Trail was one of the better running descents in the Santa Monica Mountains. From the Tri Peaks Trail junction to the Old Boney Trail it drops about 1500′ over three miles. Today, except for the stretch of trail near Chamberlain Rock, it was nearly back to its original form.
As in other areas of the Santa Monica Mountains, the effect of the heavy December rains was evident. The red shanks, and chaparral in general, seemed to be greener. This year there is a bumper crop of holly-leaved cherries, which must make the coyotes happy. Unlike last year, it looks like there should be some Christmas berries this Winter, since a number of Toyon were covered in green berries.
On the way down the Chamberlain Trail I started to fret that the water at Danielson might not be turned on. The water faucets in Sycamore Canyon are usually dependable, but on a run a few years ago the water system was turned off for servicing. Or what if there had been a drought-related water supply issue?
It turned out the water was still on, and I drank a lot of it. The remainder of the run went well, although I was a little surprised that the sensor on my pack recorded temps in the nineties in Sycamore Canyon. I had expected the south-facing stretch on Danielson road to be torrid, but a nice breeze kept the temperature tolerable.
Downtown Los Angeles (USC) ended the Rain Year (July 1, 2021 – June 30, 2022) with 12.40 inches of rain. This is about 87% of the 1991-2020 Climate Normal of 14.25 inches.
In part because of large amount of rainfall during December — nearly 9.5 inches at Los Angeles — and the meager amount of rain the previous year, the area’s vegetation responded as if there had been above average rainfall. Wildflowers bloomed in abundance and some trails became overgrown.
Yep, that was a rumble of thunder. It was a blustery, Spring-like afternoon and a storm cell had developed a few miles to the WNW of Lasky Mesa.
Before driving over to Ahmanson I’d checked the weather radar and seen cells circulating counterclockwise around a cold upper level low. Most were dissipating as they moved north to south, out over the Valley. The wildcard was that the upper low was moving southward, and the cells might strengthen.
Again there was a low rumble. The cell didn’t seem any closer, but now I could see additional development to the north and northeast of Ahmanson. I picked up the pace.
There’s nothing like the threat and energy of a thunderstorm to incentivize a runner. All the way back to the trailhead it looked like heck might break loose at any moment.
But it didn’t. It was just starting to rain when I got back to the car, and on the way home the streets were wet. The Cheeseboro RAWS recorded 0.06 inch of rain, as did Downtown Los Angeles (USC).
Even though the Rain and Water Year rainfall totals for Los Angeles are about normal for the date, January and February have seen little rain. Precipitation records for Los Angeles indicate the period January 1 to February 28 will be the fourth driest on record.
The precipitation outlooks for Southern California this March don’t look especially promising, with a typical La Nina precipitation pattern expected for the West Coast.
