Note: The Mt. Disappointment Endurance Run is now the Angeles National Forest Trail Race.

Updated 8/05/09. Added browser view of GPS trace of the course. Uses Google Earth plugin.

Updated 8/20/08. Added Split Rank listings (PDF) for 2007 50K and 50M, and related comments.

Winding down the precipitous Mt. Wilson road, I thought about the run ahead. To my left granite and pine glowed golden in the morning sun, and to my right the mountain plunged in long shadows, 2000′ into the canyon of the West Fork San Gabriel River.

In a few hours I would be somewhere down in that canyon, plodding along sun-baked Red Box road. By then the temperature would be in the mid-eighties, but in the full sun it would feel like a hundred. That would be around mile 23. I kicked a pebble and winced as it almost hit the heel of the runner in front of me. Only at mile 1-something, there were a lot of miles to go.

This was the fourth running of the Mt. Disappointment 50K, and my fourth as well. If ever a race route mirrored the character of its organizer, the Mt. Disappointment Endurance Runs reflect the tough and tenacious character of race director Gary Hilliard. Starting and ending near the summit of 5710′ Mt. Wilson, the figure-8 50K course is a challenging mix of mostly single track trails and dirt roads with an honest 5800′ of elevation gain/loss. A very difficult 50 mile option was added in 2007, and is a favorite of runners training for the Angeles Crest 100.

Even for the experienced trail runner, the Mt. Disappointment 50K is no gimme. Consider the following stat:


Nearly half (44%) of the 5800′ of elevation gain is in the last 5.3 miles of the 31.5 mile race!

Did you push the downhills too hard? Not eat enough? Electrolytes low? Whatever miscalculations have been made earlier in the race will be rung up here — ka-ching! The runner that has nothing left for this climb can take hours to complete it.

One possible gotcha is that 8.6 miles of the first 11 miles are downhill, and it is very difficult to resist being swept along by gravity and the crowd. The early enthusiasm of surrounding runners is contagious.  In 2007, I pushed the pace to Clear Creek too hard, and bonked on the backside of Strawberry Peak. I could barely run. The uphill stretch on the Strawberry Trail to Lawlor Saddle seemed to go on forever, and even the downhill to Red Box was hard to run. I didn’t see how I could finish the race.

How bad did it get? Out of curiosity I used the splits from the 2007 race to calculate each runner’s rank at each aid station, as well as their time between each aid station. At Clear Creek my rank was 58th, and by Red Box it had blossomed to 82nd. That means between Clear Creek and Red Box I was passed (and encouraged) by 24 runners. Here are the calculated 2007 50K Split Ranks and the 2007 50M Split Ranks. Some splits were missing and had to be estimated — these could be wildly inaccurate.

I did finish, but it wasn’t fun. This year I was determined not to repeat that experience. The plan was to be about 10 minutes slower at the Clear Creek aid station; gain back that time, and more, by Red Box (Aid #3); run the Red Box Rd. segment in about an hour; and then do the final climb back to Mt. Wilson in about 1:40. That would put me closer to my 2005 and 2006 times.

Here are some notes from along the way. Times are from aid station to aid station, and are approximate.

Mile 0 to 5.7 (Red Box Aid #1): Kept the pace easy on the paved road down to Eaton Saddle. Didn’t push the climb up Mt. Disappointment, or on the steep, switchbacking trail down to the Mt. Wilson road. 2007: 59 min 2008: 66 min

Mile 5.7 to 10.8 (Clear Creek Aid #2): Continued to hold back some on the pace down the old roadbed to Switzers. Felt good on the short climb from Switzers to Clear Creek and passed a couple of runners. 2007: 58 min 2008: 63 min

Mile 10.8 to 21.2 (Red Box Aid #3): Ran some of the more gradual uphill stretches on the Josephine Fire Road, but walked the majority of it. Passed a few people. The average grade of the 2.8 mile segment up the Josephine Fire Road is about 520 ft./mile, which is somewhat less than Kenyon-Devore’s 616 ft/mile. Enjoyed some watermelon and chips at the “water only” aid station at the top of the climb (mile 13.4). Time up the hill was 43 minutes — about the same as in 2007. Unlike last year was able to run and enjoy most of the Colby Canyon Trail, as well as the downhill from Lawlor Saddle to Red Box. The uphill stretch from the Colby Canyon Trail JUnction to Lawlor Saddle was still a long — and warm — 1.8 miles. Its average grade is about 411 ft/mile. 2007: 172 min 2008: 150 min

Mile 21.2 to 26.2 (West Fork Aid #4): In previous years this section has been the most difficult for me, and it was again this year. I could whine about the heat, but I think this is where extra training miles would make a big difference. I was happy to see the creeks running again this year, and stopped a couple of times to dump water on my head. Ahhhh… 2007: 66 min 2008: 61 min

Mile 26.2 to 31.5 (Finish on Mt. Wilson): By the time I got to the West Fork aid station, I was ready for something other than downhill. At the aid station I gulped down three cups of defizzed Coke and some water, and refilled one bottle with Heed and the other with ice and water. I still had two GU’s for quick energy later in the climb. I was able to run part of the 1.5 miles up the canyon to where the Kenyon DeVore trail splits from the Gabrielino trail, and the 3.1 mile Kenyon-Devore trail went well. Many of my long trail runs this Summer — in the Sierra, San Gabriels and on San Gorgonio — have been on steep terrain, and that, along with a slower start, probably helped here. 2007: 112 min 2008: 100 min

Overall, my time was 27 minutes faster than in 2007. But that’s just a figure on paper and doesn’t begin to describe how much better I felt during the race, and how much more I enjoyed it. Start slow, start slow, START SLOW is an ultrarunning adage we all know, but in the fervor of race it is often one of the first maxims that is forgotten.

Again this year, Gary Hilliard and crew made sure everything was just so — trails, aid, awards, finish line food, 2000 lbs. of ice, Brooks t-shirt, goody bag and more. Always an adventure, the Mt. Disappointment 50K is a trail running classic. Many thanks to all that make it happen!

Here’s a Google Earth image, Google Earth KMZ file, and Cesium browser View of a GPS trace of the course, with mile splits generated by SportTracks. In Google Earth, click on the red icon for the split time, pace and elevation change.

The title photograph was taken at about mile 17.5 on the course, just past the junction of the Strawberry and Colby Canyon trails, and is looking back at the terrain traversed by the Colby Canyon Trail on the north side of Strawberry Peak. It is from November 2007.

P.S. About 20 minutes after I finished the 50K, Jorge Pacheco completed the 50 mile race in an astounding 7:41, crushing the course record he set last year by almost 45 minutes! Full results are posted on the Mt. Disappointment Endurance Runs web site.

Hexagonal Close Packing

Hexagonal close packing of the disk florets of an immature Sneezeweed blossom.

There are some imperfections, but generally the unopened disk florets comprising the head of this immature sneezeweed blossom are arranged so that each floret is surrounded by six other florets. This is an example of hexagonal close packing, and is probably the most dense arrangement of florets that can be achieved in this spherical flower head.

The photograph of the Bigelow’s sneezeweed (Helenium bigelovii) was taken on an out and back run on the Pacific Crest Trail from Vincent Gap to Little Jimmy Spring during July 2007.

Did Lightning Start the 2002 Curve Fire?

Or did the Curve Fire trigger a lightning strike?

These trees — on a section of the Pacific Crest Trail east of Windy Gap — were burned almost six years ago in the 20,857 acre Curve Fire. According to the Curve Fire Burned Area Emergency Report Implementation Plan, the source of ignition for the devastating fire was “a ritual involving the use of fire (candles) and animal sacrifices.” The fire started the afternoon of September 1, 2002.

However, in the document An Exercise Involving Flash Flood and Lightning Potential Forecasts, an alternative ignition source was suggested — an “out of the blue” lightning strike. Forecasters observed a “single positive lightning strike northeast of the Mount Wilson Observatory” about 1:00 PM PDT (2000Z), near the time the Curve Fire started. According to NWS Lightning Safety Outdoors, such bolts from the blue have been documented to travel more than 25 miles from a thunderstorm cloud.

While there is compelling evidence that the blue sky lightning strike occurred, the time of the strike suggests that it was not the initial source of ignition of the Curve Fire. This UCLA Solar Towercam image is time-stamped at 12:58:58, about the time of the strike. It shows the Curve Fire already underway, with a well-developed smoke column. The photograph also shows the cloud development over the San Gabriel Mountains.

An intriguing question comes to mind. Was the lightning strike a coincidence, or was it somehow triggered by the fire, or the smoke?

According to “Forest Fires: Behavior and Ecological Effects” by Edward A. Johnson, Kiyoko Miyanishi (Academic Press, 2001) large scale lightning detection networks have revealed an association between forest fires and the electrification of thunderstorms. Further, “a shift from negative to positive ground flash prevalence in association with fires and forest fire smoke” has been documented.

So it looks like lightning did not start the Curve Fire, but the Curve Fire may have triggered the positive lightning strike observed by the NWS!

The photograph of trees burned in the Curve Fire is from Sunday’s Islip Saddle – Mt. Baden-Powell South Fork run.

Islip Saddle – Mt. Baden-Powell South Fork Loop

first published & last updated

View of the South Fork Big Rock Creek and Devil's Punchbowl from Mt. Baden-Powell.

Maybe it’s because it’s been in the news recently,  but when pondering how to characterize today’s trail run, I couldn’t help but think of the JFK quote, “We do these things not because they are easy but because they are hard…” This loop is arduous, adventurous, and challenging. While the difficulty of this route is one of the things that makes it interesting, it isn’t just the difficulty that makes it appealing.

Part of the appeal is the mix of trails and terrain, and the contrasting environments. The high point of the route is 9,399′ Mt. Baden-Powell. Cool, airy and alpine, it is the home of ancient Lodgepole and Limber pines. The low point of the route is 4,560′ South Fork Campground. On the margin of the Mojave Desert, it is often hot and sometimes torrid. Midday temperatures here can reach well over 100°F. The route encompasses life zones ranging from the Upper Sonoran to the Hudsonian, and passes through a variety of plant communities. The San Andreas Fault Zone runs along the base of the mountains, torturing the area’s rocks, and producing a complex and fascinating geology.


Erosion gulley on the Manzanita Trail.
From Islip Saddle the route descends the South Fork trail to South Fork Campground, then climbs 5000′ on the Manzanita and Pacific Crest trails to the summit of Mt. Baden-Powell. From here it follows the PCT back to Islip Saddle. In general, the part of the route that is on the PCT — above Hwy 2 — is well marked and maintained. However, on the South Fork and Manzanita trails — below Hwy 2 — you are on your own.

There are rock slides on the South Fork trail, and there are steep, washed out erosion gullies on the Manzanita trail. Recent thunderstorms have further damaged the eroded sections of the Manzanita Trail. In addition, the Manzanita trail crosses boulder-strewn washes that can make the trail difficult to follow. It is not a trail I would want to be on when there is heavy rainfall. The South Fork and Manzanita trails are part of the High Desert National Recreation Trail.

Chumash Trail Racers

Red coachwhip snake (Masticophis flagellum piceus) on the Chumash Trail, near Simi Valley, California.

Encountered this red coachwhip/racer (Masticophis flagellum piceus) as I was running down the Chumash Trail today. It was a long snake — at least 5′.

In June 2005, I found a California striped racer (Masticophis lateralis lateralis) on the Chumash Trail that appeared to have suffered some sort of fatal trauma. It was a much smaller snake than the red racer.

Note: There was a handwritten notice posted at the Chumash trailhead warning of a mountain lion sighting on July 18, 2008. I haven’t been able to obtain any additional details.
