Up, Down and Around on Mt. Pinos’ Tumamait and North Fork Trails

A Chumash spirit tower on Sawmill Mountain, near Mt. Pinos

Yellows, reds and greens marked its location, but the seep above Sheep Camp was dry. As I approached the camp, the uppermost campsite was empty and I wondered if the spring at the camp was also going to be dry. If it was, I was going to have to revise my running plan.

So far the run had gone well. From the Chula Vista parking area (8350′), I’d run the service road up to Mt. Pinos (8831′), then followed the Tumamait Trail west to Mt. Abel Road. Along the way Sawmill Mountain (8818′)and Grouse Mountain (8582′) had been short side trips; and from the end of the trail, the summit of Mt. Abel (8280′) was a short hike up through the pines.

Compared to the triple-digit temperatures in the parched West Valley — as high as 117 °F this July — the temps on the Tumamait Trail had been wonderfully cool. The hotter than average weather seems to have become the new norm, and also — unfortunately — the resulting wildfires.

On a run here Last July, smoke from a fire near Lake Cachuma had nearly enveloped Mt. Pinos. Today several fires were burning in California, and once again smoke could be seen in the valleys and canyons to the north of the mountain.

To get in a bit more mileage and elevation gain the next part of my run was supposed to be an out and back to the sun-baked environs of Lily Meadows (6600′). That wasn’t going to happen if the spring was dry.

When I stopped at the wildflower-accented spring I could see that there was the barest thread of water trickling from the pipe. It didn’t look like much, but it filled my 18 oz. cut-off water bottle in about three minutes. I gulped down most of the first bottle and it took a couple more to fill my Camelbak. In about 10 minutes I was headed downhill.

The North Fork Trail is far less used than the Tumamait Trail. That’s part of the fun. Thunderstorms had not only wiped away any previous tracks, but had severely eroded some sections of the trail as well.

With the loss of elevation came an increase in temperature. By the time I reached Lily Meadows Camp the temp was in the 90s. This time of year there were no lilies or meadows at the campsite, but there was a nice grove of Jeffrey pines and a new camp table!

I didn’t spend much time down there. There was a hill to climb and the cool temps along the crest were only about an hour away.

Lemon Lilies, Tree Rings and More Heat Training on the Three Points Loop

Lemon lily and sneezeweed at Waterman Meadow in the San Gabriel Mountains.

There seems to have been some carryover from the wet rainy season we had in 2016-17 to this year. The 2017-18 rain season was very dry — the third driest on record at Downtown Los Angeles — but seeps at Waterman Meadow, along the Burkhart Trail below Buckhorn were still wet. In general plant growth along trails has been more than I expected in such a dry year.

Wet and dry periods can be seen in the growth rings of the large Jeffrey pine along the Three Points – Mt. Waterman Trail just west of the Twin Peaks Trail junction. A more careful count of its rings totaled about 500. No matter how careful the count, because of the various anomalies that occur with tree rings, some form of crossdating is usually required to confidently assess the age of a tree. Even so, it is clear this was an old tree.

The first few miles of the loop were gloriously cool, but by the time I reached Cooper Canyon and was working up to Cloudburst Summit on the PCT, the sun beat down on me in a familiar refrain.

Here are a few photos taken on the loop.

Another Scorching Angeles National Forest/Mt. Disappointment Trail Race

Sunrise on Mt. Wilson prior to the start of the 2018 Angeles National Forest/Mt. Disappointment Trail Race

It was “déjà vu all over again” for the 12th running of the Angeles National Forest Trail Race on Saturday. When the sun rose over Mt. Wilson Saturday morning, the temperature was already in the 80s and monsoon clouds were scattered across the eastern sky. We all knew it was going to be a hot day. The only question was how hot?

Following weeks of seasonable — and often cool — weather, temps began to ramp up Thursday. On Friday many daily and some all-time record high temps were set around the Los Angeles area. Van Nuys set an all-time record high of 115°F. Downtown Los Angeles set a new daily record of 108°F and Woodland Hills set a new daily record of 117°F.

The record-breaking heatwave continued race day with temps on the ANFTR course surpassing the torrid temps of 2017. The Clear Creek RAWS recorded average hourly temperatures as high as 100°F and average hourly fuel temps as high as 123°F. The highest temperature measured at Clear Creek was 105°F — five degrees higher than last year’s race.

Once again, despite the heat, there were some AMAZING performances. In the 60K, first and second place in both the Mens and Womens division finished only a couple minutes apart. Mario Martinez’s 6:41:25 just edged Rupert Romero’s 6:43:27, and Katie Asmuth’s 7:29:11 was just ahead of Teresa Kaiser’s 7:32:21. Chase Coffey ran the 50K in 4:25:26, which I believe is the fastest time for the normal 50K course. (In 2009 we ran all the way to Red Box on Mt. Wilson road.) Ana Suchey was the top woman in the 50K with a time of 6:04:30. In the 25K Victor Martinez bested the record he set last year, running the course in 2:07:27. Jennifer Sunahara was first among the women, with a time of 2:58:29. Not all the great performances were from the fastest runners. Sa Il Hong, age 80, completed the 50K in fine form.

Many thanks to Gary and Pam Hilliard and all the ANFTR staff and volunteers! It wasn’t just hot for the runners! And those setting up the event and marking the course had to endure Friday’s record-setting temps, spend a warm night on the mountain, and then work in the heat again on Saturday!

See the ANFTR web site, Facebook page and Facebook group for more info. The Angeles National Forest Trail Race is the new name for the Mt. Disappointment Endurance Run. Only the name changed. All the results for the ANFTR/Mt. Disappointment races since 2005 can be found on Ultrasignup.com.

Note: The temperature in a commercial weather station is measured inside a white, ventilated instrument housing, several feet off the ground. Mid-day temperatures in the sun, in the summer, with a cloudless sky will be much warmer than this. Some stations, such as Clear Creek, also measure the fuel temperature — the temperature of a pine dowel in direct sun about a foot off the ground. According to the NWS (and common sense) exposure to full sunshine can increase heat index values by up to 15°F. In my experience the fuel temp gives a better indication of the actual temperature a runner can experience in the sun, especially on exposed mountain slopes facing the sun.

Still a Little Snow in Southern California

Snow patch at about 11,000' on San Gorgonio Mountain on June 9, 2018.

Given that Southern California has had way below average precipitation this rain year, I was a little surprised to find a few widely scattered patches of snow on San Gorgonio Mountain this past Saturday.

The patch of snow in the title photograph was at 11,000′, about a mile from San Gorgonio’s summit. This Google Earth image from last year shows an overview of the area. There was a lot more snow last year, but the same patch — in a deposition area — is near the “San Bern” in the “San Bernardino Peak Divide Trail” label.

There was “shorts and short sleeves” weather for the entire run from the South Fork trailhead.

Here are a few photos taken along the way.

Cool Weather, Old Trees, Grape Soda Lupine and a Restored Trail

Section of Three Points - Mt. Waterman Trail cleared of trees killed in the 2009 Station Fire.

The weather was surprisingly cool for a Memorial Day weekend in the San Gabriel Mountains. At Three Points (5925′) the temperature was a brisk 43°F when I started my run, and it remained in the 40s as I worked up the Three Points – Mt. Waterman Trail toward Twin Peaks and Mt. Waterman. The trail from Three Points is a long-time favorite and part of an adventurous — and scenic — 20 mile loop around Waterman Mountain.

In 2009 the Station Fire ran up the ribs and gullies of the south face of Mt. Waterman, ravaging some slopes, but leaving others untouched. Many trees were killed, including some old growth incense cedars and Jeffrey pines. On a run in March 2017 I counted more than 40 dead trees down on the trail. At that time a few trees had already been cleared from the trail and in the following months many more would be.

One particularly hard hit area is about a half-mile west of the Twin Peaks Trail junction. Last Summer dead trees blocked the trail in this area and in places were stacked one on top of another. The title photo is of the same area after the trail was cleared.

On a previous run I’d photographed the growth rings of a burned Jeffrey pine above the Twin Peaks Trail junction and estimated the total at about 325. Today, a recently cut Jeffrey pine just west of the Twin Peaks Trail looked like it might be considerably older. A very rough count of its rings totaled 475.

On this run the Three Points – Mt. Waterman Trail was almost entirely clear of trees and in the best condition I’ve seen since the Station Fire. Many thanks to Alan and the SoCal Hikers & Trail Builders for restoring this trail!

Here are a few photos from the run.

Breezy San Bruno Mountain Ridge

Running along the San Bruno Mountain Ridge Trail

I staggered in the wind gust. It had to have been at least 45 mph. The views along the undulating ridge to the Bay were spectacular, but the wind was ferocious.

Brett and I were running on the San Bruno Mountain Ridge Trail. We’d started at the summit parking lot and weren’t exactly sure where we were going to turn around. We’d know when we got to it.

The NWS forecast for San Francisco had called for “breezy” conditions:

.TODAY…Mostly cloudy in the morning then becoming partly
cloudy. Breezy. Patchy drizzle in the morning. Highs in the mid
50s to lower 60s. West winds 20 to 30 mph.

Continuing down, down, down the ridge.

That forecast was for the city — and of course up on the peak the wind was even “breezier.” The SF Giants beanie I borrowed was the right call. So were the gloves, extra shirt and wind shell.

We continued along the ridge past the second set of loudly singing power lines and continued downhill. It became one of those, “let’s just go down to that next overlook,” and then the next one, and the next one. Not only were we losing a lot of elevation, but we’d be running into the wind on the way back.

We eventually turned around a little above Bayshore Blvd., at the “Sierra Point Reset” benchmark marked “487” on the topo map. As is often the case, the return wasn’t nearly as torturous as envisioned, but I was glad to get back to the car!

San Bruno Mountain is an invaluable island of open space, about 20 minutes from downtown San Francisco. For more information see the San Bruno Mountain Watch website.
