Snow-Covered San Gabriel Mountains From Lasky Mesa

Snow-covered San Gabriel Mountains from Lasky Mesa in Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch)

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.

The paved turnout where I usually park at the Stunt Road trailhead was covered with mud, rocks, and debris. And near the entrance of Calabasas Peak fire road, two large boulders had been dragged to the shoulder to clear the road.

Following another big storm in a Winter of big storms, I was doing the Topanga Lookout Ridge Loop — curious to see what I could see. Nearby Stunt Ranch Reserve had recorded over 10 inches of rain the past three days, and there had been numerous reports of low elevation snow.

Here’s a slideshow of what I found.

Chasing a Sunrise, Taking a Moonshot, Los Padres Snow, and a Dark Line in the Sky

Colorful sunrise in the eastern Santa Monica Mountains

I was running up Calabasas Peak Mtwy fire road trying to get a better view of the eastern sky, but the view in that direction was blocked by a steep hillside. The road turned to the northeast up ahead, and I hoped the best moments of a rapidly-evolving sunrise would not be lost.

A couple of breathless minutes later, I rounded a corner and was rewarded with an unobstructed view of a vivid, pink-red-orange mackerel sky. Focusing on the ridgeline near Topanga tower, I shot several sets of bracketed photos.

Excited by the sunrise, I continued up the fire road, scanning my surroundings for another photo. My eye settled on the gibbous moon. High in the sky, it’s bright face was subdued by a thin veil of pinkish-gray cloud. I’d previously experimented with handheld shots of the Moon using my running camera — a Lumix ZS100. Zooming to an equivalent focal length of about 250mm, I held my breath, steadied the camera the best I could, and took a few shots. Here’s one of the images — cropped and sharpened — with enough detail to see craters, maria, and some other lunar features.

At the bottom of Topanga Lookout Ridge there were several bigberry manzanita bushes covered with flowers. A hummingbird was up before sunrise, buzzing about the blossoms, busily drinking the precious nectar. Although it had rained a couple days before, this rain year there had been little rainfall, and a corresponding scarcity of early season wildflowers.

As I climbed higher on the ridge, the mountains northwest of Los Angeles came into view, white with snow from the recent storm. The snow-covered peaks are south of Mt. Pinos and Frazier Mountain, in the area of San Raphael Peak, McDonald Peak, Sewart Mountain and Snowy Peak.

Like snow on a mountain, there is a purity in the form and appearance of clouds. When a long, dark streak appeared across a layer of high clouds, it was hard to miss. In this case, the dark line appears to be the shadow of a contrail of a jet flying above the clouds. At the time LAX was reporting scattered clouds at 19,000′ and 23,000′, with a broken layer of clouds at 28,000′. Given the height of the clouds and orientation of the contrail, it may have been from a flight from San Diego to San Francisco.

Topping out on the ridge, I smiled when I saw the masked couple dancing on the Lookout, and continued west toward Saddle Peak.

Hard Winter

Broken lodgepole pine near Throop Peak

The out and back to Mt. Baden-Powell from Islip Saddle has become a springtime running ritual for me. Sometime in April, May or June, I like to get back to the high country, and see what there is to see — including whether there’s any snow left on Baden-Powell or Mt. Baldy.

Sentinel satellite imagery showed a lot of snow along the crest at the end of April, but hot weather and dry winds in May accelerated the melt. By early June most of it was gone. It didn’t seem likely I would see any today.

I hadn’t seen any snow along the trail this morning. I’d run past Little Jimmy Camp, Windy Gap, Peak 8426, and was now at an elevation of about 8700′, near Mt. Hawkins. Above me, I could hear the excited voices of a couple of hikers near its summit. Thinking they might be part of a group, I looked up the trail toward the crest.

Something was missing… Where was it? Usually prominent on the skyline at this point, the “Mt. Hawkins Lightning Tree” was gone. I walked up the trail to look for the familiar landmark. The trunk of the lightning-scarred Jeffrey pine had been snapped like a twig. The crown of the tree lay 50 yards down the steep slope, jammed against two trees.

It must have been a hard Winter. Several other live trees along the crest between Mt. Hawkins and Mt. Baden-Powell were either blown down or broken in half. In some cases, the damaging winds appeared to be from the south side of the crest and in others from the north. December 2019 was stormy in Southern California, particularly around Christmas. Weather data suggests this might have been when most of the damage was done.

Today, only two large trees blocked the trail. One, on the west side of Mt. Burnham, was easy to go under or around, but the other, west of Throop Peak, was a bit more of a challenge. Given the brush on either side, climbing over the tree worked for me. Some others had detoured well above or below the tree.

Surprise, surprise! It turned out there were a couple of small patches of snow on the north side of the crest near Baden-Powell. These were the remnants of an area of wind-deposited snow on the lee (north) side of the crest between Mt. Baden-Powell and Mt. Burnham. Large drifts can collect here, and in a heavy snow year, can persist into July. The deposition area can be seen in the Sentinel satellite image.

With its long views, sub-alpine elevation, and weather-worn limber and lodgepole pines, Baden-Powell is a rewarding summit. Just a few miles to the southeast, Mt. Baldy looms above a mile-deep canyon. If the visibility is good, San Jacinto Peak and San Gorgonio Mountain can be seen beyond Mt. Baldy, many miles in the distance.

The distance from Islip Saddle to Mt. Baden-Powell (9,399′), and back, is about 16 miles. The cumulative elevation gain is about 3800′. Here’s an interactive, 3D view of the out and back route.

Trail note: I ran into a “misplaced” hiker that didn’t know what trail they were on or where they started. Take the time to familiarize yourself with the adventure you have planned!

Chilly Rocky Peak

Rocky Peak Road is one of my go-to wet weather running spots. The sandy soil — thanks to the Chatsworth Formation sandstone — doesn’t cake on your shoes when it’s wet. It isn’t entirely mud-free, but as long as you don’t mind a few steep hills, it’s a good choice when the weather turns wet.

According to preliminary rainfall totals tabulated by the NWS, Rocky Peak recorded 1.22 inches of rain during the Christmas storm. The snow level had been forecast to drop to 2000′-2500′ in some areas, so as the storm was breaking up I headed over to Rocky Peak to get in a run, and see what I could see.

I’d dressed for a cool and breezy run, and was comfortable as I worked up the first steep hill. But I hadn’t run half a mile when I stopped and put on some gloves and a pair of stretch shorts. That helped, but the higher I went the colder it got. Up top, a little past Rocky Peak, my thermometer registered a chilly 38 degrees and the wind was gusting 10-15 mph. According to the NWS Wind Chill chart, that put the effective temperature at around 30 degrees.

And that’s what it felt like. Part of the problem was that I was running into the wind, which increased the chill. I had a wind shell in my pack, but once I’d reached my turnaround point and had the wind at my back, it wasn’t needed.

There was no snow on Rocky Peak Road or Oat Mountain, but from time to time the setting sun broke through the clouds and highlighted the snow on the nearby mountains. It was a far different scene than on the usual Rocky Peak run.

December has been wet in the Los Angeles area. As of December 27, Downtown Los Angeles (USC) has recorded 4.84 inches of rain this December, which is nearly three inches above normal. Rain year and water year precipitation totals are also well above normal, and at the moment, ahead of last year. We’ll see what the new year brings!

Update January 24, 2020. Well, the new year hasn’t brought us much in the way of precipitation. January in Downtown Los Angeles has been about as dry as December was wet. So far, Downtown Los Angeles has recorded only 0.32 inch of rain this January, well below the climate normal for the date. If there is no additional rain this month, Los Angeles will end the month with about normal rainfall to date for the Rain Year (Jul 1 – Jun 30) and Water Year (Oct 1 – Sep 30). Then we’ll have to see if there is a pattern change in February, or if it is also drier than normal, as most guidance suggests.
