Developing thunderstorm over the Acton area, north of Los Angeles, from Ahmanson Ranch near the Los Angeles County – Ventura County border. The photo was taken about 4:10 p.m. PDT today, during another hot and humid Ahmanson run.
Cloud tops were reported to be over 50,000 feet. The distance from Ahmanson Ranch (now Upper Las Virgenes Canyon Open Space Preserve) to Acton is about 35 miles.
The heat was oppressive. The air was sweltering and still, reminding me of hot nights in the South, when heat lightning flashed on the horizon, and any movement was an effort. An adductor muscle in my left leg started to cramp and I jumped up from the reclining chair. Heat, and more heat had been the theme of this day. I had returned home from running my eleventh, and hottest, Mt. Disappointment 50K, only to be caught in a widespread power failure caused by a transformer explosion and fire in a Northridge distribution station.
How hot was it for the 2017 Mt. Disappointment races on Mt. Wilson?
– Between 11:00 a.m. and 5:00 p.m. the in the sun temps recorded by the Clear Creek RAWS (on the 50K course) ranged from 115 °F to 121 °F. Out of the sun temps ranged from 94 °F to 98 °F.
– Between 10:30 a.m. and 4:30 p.m. an ANF portable weather station adjacent to the Mt. Wilson Observatory recorded in the sun temps ranging from 106 °F to 114 °F. Out of the sun temps ranged from 92 °F to 96 °F.
– The temperature (inside a ventilated instrument housing) on Mt. Wilson at CBS Radio reached a high of 103 degrees. This appears to be the highest temperature at that location since it came online in 2008 and may have been the hottest temperature on Mt. Wilson in several decades.
– Downtown Los Angeles (USC) reached a record high for the date of 98 degrees, breaking a 131 year old record.
Even more remarkable than the weather were the performances of the top runners. Ruperto Romero was the overall winner of the 50K with an astounding time of 4:38:44. This was only a couple of minutes slower than his winning 2015 time — when temps were 20-30 degrees cooler. In what must have been an exciting finish in the Women’s division, Elizabeth Ochoa cranked out a 6:19:45, just edging out Ana Guijarro by eight seconds. Victor Martinez won the 25K in 2:08:01, with Jay Nadeau taking the top women’s time in 3:05:13. All the Mt. Disappointment results are available on UltraSignup.
The heat continued to build past noon, peaking between 1:30 p.m. and 4:30 p.m. This made for a long day for those of us in the back of the pack. At 1:00 p.m Red Box Road was a blast furnace, facing directly into the sun. I was very glad to have scouted the final seven miles of the course last weekend. The creeks crossing the road really helped to keep from becoming over-heated. Strayns Creek on the Kenyon Devore climb also helped me to cool down.
Many thanks to Gary and Pam Hilliard and all the Mt. Disappointment staff, volunteers, sponsors and runners. The aid station personnel were phenomenal, and all their assistance was much appreciated. The efforts of the Forest Service were also much appreciated. ANF personnel were on the trails and at the aid stations, helping runners.
The photograph above was taken a little more than a mile from the top of the Kenyon Devore Trail, in the San Gabriel Mountains, near Mt. Wilson. The deep canyon seen through the trees is Strayns Canyon, which the trail follows on its way from the West Fork San Gabriel River to the shoulder of Mt. Wilson.
Today, I’d run down the Kenyon Devore and Gabrieleno Trails to West Fork and then up the Red Box – Rincon Road to point on the map marked Camp Ah-DA-Hi. (A former Woodcraft Rangers Camp.) With hot weather forecast next Saturday for the Mt. Disappointment 50K, I’d been glad to see the small streams that had been dry during the drought were running again.
Trails have stories to tell and when I run or hike a trail I’m always curious about its history. A trail between the West Fork San Gabriel River and Mt. Wilson is shown in the 1:62500 1897 edition of the USGS 1894 Los Angeles Sheet. Like many trails of the era, it followed a ridge, in this case a ridge just east of Strayns Canyon.
The first USGS map to show a trail along Strayns Creek was the 1:24000 1934 Mt. Wilson Advance Sheet. The trail remained unnamed in USGS maps until the 1966 edition of the 1:24000 Mt. Wilson Quadrangle, when it was labeled the Rattlesnake Trail. The trail was renamed the Kenyon Devore Trail in the 1995 edition of the map in tribute to Forest Service patrolman, hydrographer, and Angeles National Forest volunteer, Kenyon DeVore.
The Kenyon Devore Trail is part of the Mt. Disappointment 50K course. It is one of several trails maintained by runner-volunteers under the guidance of Forest Service volunteer and Mt. Disappointment Race Director, Gary Hilliard. Today, as I was on my way back up to Mt. Wilson, I ran into Gary and two volunteers cutting logs from the trail in preparation for next Saturday’s event.
I have to laugh about what happened on the Kenyon Devore climb one hot year. I’d jammed my Camelbak(TM) with so much ice at the West Fork aid station that when water was added, it melded and froze into one large chunk. I didn’t discover this until about halfway up the climb, when I ran out of water. You can’t drink a chunk of ice and even at 90 degrees, the ice was melting at an agonizingly slow rate. At best I could only get a minuscule sip of water from the pack every few minutes, and it nearly imploded from my efforts.
We were nearly to the junction of the Pacific Crest Trail and the South Ridge Trail and about a half-mile from Tahquitz Peak (8846′). It was hot. In the shade the temp was in the high 80s, but in direct sun the temperature was close to 100°F.
A few hours earlier Skye and I had grabbed the first car up on the Palm Springs Tram and done the 5 mile, 2435′ ascent of San Jacinto Peak. At 10,800’+ at 10:00 in the morning it had been 70°F — warm for one of the higher mountains of Southern California. Remarkably, a couple of small patches of snow remained on the south side of the summit.
Where we were now, 70 degrees would feel like a refrigerator. We’d given up that cooler clime and all the elevation we’d gained, and run five miles down the Wellman Divide Trail and PCT to Saddle Junction — a descent of about 2700′. The temperature had increased all the way down.
We might as well have been in a drying oven. The combination of the hot weather, a high sun, low humidity and higher altitude had desiccated me. At the turn-off off from the PCT to Tahquitz Peak I lifted my pack and squeezed the reservoir — again. In the few minutes since I last checked, no water had magically found its way into my pack. There was less than 20 ounces remaining and that wasn’t going to be enough.
After running over to Tahquitz Peak and visiting the lookout, there was still the minor detail of getting back to the Tram. The Mountain Fire closure was still in effect, which meant we could not use the Willow Springs Trail and would have to retrace our steps and climb all the way back up to Wellman Divide.
During the drought I would bring extra water when doing this route, and stash it along the trail. With this year’s good snowpack it seemed we should be able to find water if we needed it.
Prior to the Mountain Fire I’d used Willow Creek as a water source, but since the Willow Springs Trail was closed, that was out. The seep at Wellman Cienaga was too far up and the flow was low. Skunk Cabbage Meadow and Tahquitz Valley were a possibility. Originally included in the Mountain Fire closure area, they had reopened. I recalled a water source in Skunk Cabbage Meadow, but didn’t remember much about it.
When we got to Tahquitz Peak we asked Joe, the volunteer Ranger at the Tahquitz Peak Lookout, what he thought would be a good water source. He suggested Tahquitz Creek in Tahquitz Valley. I hadn’t been to Tahquitz Valley, so this was a great time to check it out.
Although small in its upper reaches, Tahquitz Creek had plenty of water. Using a UV Pen, we refilled our packs and drank until we couldn’t drink any more. Continuing, we found there was also water available at Skunk Cabbage Meadow. At least for now. I wouldn’t hazard a guess how long these water sources will last.
Ah water, wonderful water. With water the hike and run back to Wellman Divide was just a sweaty, strenuous and scenic climb, and not the hellish ascent it might have been.
Each year around Memorial Day weekend I like to do a run that includes Mt. Baden-Powell (9399′). It’s a good time to check how much snow remains at the higher elevations of the San Gabriel Mountains. In a heavy snow season, such as 2004-2005, higher sections of trail may still be buried in snow and drifts can persist into July. In below average years, such as we experienced from 2013 to 2016, there may be little or no snow.
There are several good runs that summit Mt. Baden-Powell. If Hwy 2 is still closed between Islip Saddle and Vincent Gap, I’ll usually do an out and back from Islip Saddle to Mt. Baden-Powell. If Hwy 2 is open, then a point to point run from Inspiration Point to Islip Saddle or Eagles Roost is a good option. Today the choice was one of my favorite loops in the San Gabriels. It starts at Islip Saddle, descends to South Fork Campground, then climbs about 5000′ to the summit Mt. Baden-Powell. From Baden-Powell the route follows the Pacific Crest Trail back to Islip Saddle.
This was my third time on the PCT between Islip Saddle and Mt. Baden-Powell this Spring. The first was at the beginning of April and was more of a snow hike than a run. The micro spikes went on at 7000′, less than 0.7 mile from the Islip Saddle trailhead. The second trip was two weeks later, in mid-April. Micro spikes were still helpful in a couple of places and there was still plenty of snow on the north side of the crest. Based on other seasons with a similar amount of snow, I thought some patches of snow might last into June, or even early July. Today (May 27) only a few patches remain on Baden-Powell and along the crest, and these will soon be gone.
Except for being a little disappointed there wasn’t more snow, the run went well. The South Fork Trail was rocky and rough — as usual. The Manzanita Trail, which connects South Fork Campground to Vincent Gap, has seen a lot of work in recent years and is in relatively good shape. Even the gnats weren’t bad. I saw no one on the South Fork and Manzanita Trails. As might be expected on a Saturday on Memorial Day Weekend, there were “a few” hikers, thru-hikers and runners on the PCT.
It was a warm day by San Francisco standards — sunny and in the seventies. We’d planned to go “across the bridge” for today’s run, but with the great weather it seemed half the city’s residents and visitors were queued up on the streets leading to the Golden Gate Bridge. We opted for a run in the city instead.
This was not an inferior alternative. Running in the city is fun; there are many options and much to see. Today’s course took us from Industrial Light & Magic, to Mountain Lake, Land’s End, Sutro Heights, Ocean Beach and Golden Gate Park.
