Introduced around 2000, the Garmin eTrex was the first GPS unit I used to trace a trail run. The GPS tracks were imported into TOPO! where the length of a run could be measured, an elevation profile generated, and the topography of the run examined.

Since the eTrex was designed to be used in an “orienteering” position — flat in your hand in front of your body — it would frequently have trouble receiving GPS satellite signals if hand-carried while running or hiking. About the time enterprising hikers and runners began to resolve this issue with creative hats, holsters and harnesses, Garmin released the Forerunner 201, greatly simplifying the task of tracing a route.

In 2005, while preparing a presentation about kayaking Piru Creek for a meeting with the Forest Service, I stumbled onto Keyhole.com. To say I was blown away by this bit of “Eureka” technology would be an a gross understatement. Now, in addition to seeing Piru Creek in photographs, and on a topo map, you could get a “before you paddle” preview using Keyhole — even if you couldn’t paddle class IV whitewater! Google acquired Keyhole in late 2004 and launched Google Earth on June 28, 2005.

Shortly after Google Earth was launched, SportTracks added the ability to launch Google Earth and view the GPS trace of a run or other activity. Since SportTracks could also directly import data from Garmin’s Forerunner, the software made it very easy to view a run in Google Earth.

I’ve been working on updating the posts on Photography on the Run that reference a trail run to include a link to a Google Earth KMZ file. A KMZ file is just a zipped KML file, and either can be opened in Google Earth. A list of the trail runs with KMZ file links can be found by clicking “Google Earth KMZ Files of Trail Runs” in the sidebar.

These are actual tracks recorded by a GPS during a trail run and may contain GPS errors, route-finding errors, and wanderings that are difficult to explain. In a few instances tracks have been modified to correct errors, or to remove side excursions that are not part of the usual route, but not all errors have been corrected. No claim is being made regarding the appropriateness or suitability of the routes indicated.

San Gabriels High Five

Snow on the Pacific Crest Trail west of Mt. Baden-Powell, May 18, 2008.

When considering where I might run this weekend, the words “snow” and “altitude” had a certain appeal. Record high temperatures had been set in the Los Angeles area on Friday and Saturday, and there was little doubt that more temperature records would fall today.

A couple of weeks before I had dodged a few remnant snow drifts on Pleasant View Ridge. From that vantage point you could see that there was much more snow on the steep, north facing slopes along the ridge between Mt. Islip and Mt. Baden-Powell. The S-shaped ridge spans a distance of several miles and links five peaks over 8000 ft: Mt. Islip, Mt. Hawkins, Throop Peak, Mt. Burnham, and Mt. Baden-Powell. Two of the peaks, Mt. Baden-Powell and Throop Peak, exceed 9000 ft. Today, the plan was to do these five peaks as part of an approximately 17 mile out and back route from Islip Saddle, enjoy the snow before it melted, and try to escape the triple digit temps of the lowlands.

Logistically, the difficult peak is Mt. Islip. While the other peaks can be done with relatively minor deviations from the trail, Mt. Islip stands alone, more than a mile from the PCT at Windy Gap. This time I opted to climb Mt. Islip from Islip Saddle via the northwest ridge. I’ve been investigating stunted Jeffrey and Sugar pines found along the windswept ridges of the San Gabriels, and this direct approach would give me the opportunity to check out more trees.

That was this morning, now I was on by way back from Mt. Baden-Powell, and about a quarter-mile east of Throop Peak. Hot, thirsty, dispirited, and nearly out of water, I had stopped to dig into the side of a dirty snowbank– attempting to get to snow that at least looked clean. The air temperature was eighty-something, but my fingers were stinging with cold as I scooped the coarse crystals into my Camelbak.

It’s amazing what a few sips of chilled water and an icy cold pack against your back can do for your demeanor. A few minutes before I had been debating whether I should just skip Throop Peak and Mt. Hawkins, and get down to Little Jimmy Spring ASAP. Now I could do these peaks and continue to enjoy a very warm — but beautiful — day in the San Gabriel Mountains.

Here’s a Google Earth image and a Google Earth KMZ file of a GPS trace of my route. GPS reception was poor climbing the ridge to Mt. Islip.

Pleasant View Ridge Snow

Snow on Pleasant View Ridge, in the San Gabriel Mountains.

A small patch of snow crunched under foot as I worked my way west along Pleasant View Ridge. Overnight the temperature had dropped below freezing, and careful route-finding was required to work around icy patches of steep snow clinging to the ridge. In other years this might be tedious, but after last year’s parched Spring, it was enjoyable to have to wind my way through the maze of rocks, trees, chinquapin and snow.

Most of the snow could be avoided by staying on the sunny side of the ridge. but in a couple of places it was easier to drop down and around large patches of snow on the north side of the ridge. The snow was rock hard, and I wondered if the descent from the highest point along the ridge was going to be a problem. There was little doubt that the north slope of peak 8248 would be snow covered. If the snow extended to the northwest ridge and face, I might have to turn back.

Fortunately, as the photograph above shows, most of the ridge was free of snow, and I was able to continue on the loop. It was great to have snow on the peaks and water in the creeks!

Condor Peak Trail Run

Trail runner on the Condor Peak Trail as it nears Condor Peak.

The temp was in the 30’s and it took a couple of minutes for my car’s engine to warm enough to thaw the coating of ice on the windshield. I was headed for a run in the San Gabriel Mountains and was wondering how cold it might be.

In a November in which 29 days had been bone dry, it had rained on the 30th, and temps had cooled dramatically. That was day before yesterday. This morning the sky was still a storm-cleansed blue, and except for a few passing high clouds, promised to stay that way. If the winds were not too brisk, it could be one of those invigoratingly crisp late Autumn days — cold in the shadows, but warm and pleasant in the sun.

About an hour later Miklos and I were working our way up the Condor Peak Trail (13W05), not far from the trailhead on Big Tujunga Canyon Road. At the parking area I had shed some extra layers and was now running in shorts and a light long-sleeve top. In the pack were an ultralight shell, gloves, and a headband.

About a 1/4 mile from the parking area we caught up to some hikers and their dogs. They asked us if we were headed “to the top.” I replied that we were doing Fox Mountain and Condor Peak, and would continue on to the Trail Canyon Trail.

“Do you have a car at the Trail Canyon trailhead?”

“Yep…”

“You know it’s 17 miles, right?”

“Yep…”

Twenty minutes into the run, we reached the point where the old trail jumps up from Big T and joins the main trail. From here we turned north, away from the highway, and began a long, winding, uphill course that would eventually reach the divide between Fox Mountain (5033′) and Condor Peak (5440’+). This meandering approach resulted in a very runnable section of trail that gains about 2500′ in 5.5 miles — an average 8.6% grade.

As the trail wound in and out of canyons, and from shadowed to sunny slopes, the temperature contrasts were startling. Within a few feet, we would stride from balmy, solar heated granite alcoves into frosty, refrigerated nooks near freezing. We estimated the difference in temperature to be 30-40 degrees.

Gradually we gained elevation, and in about an hour and a half we crested the broad divide at the base of Fox Mountain. From this point a short — but steep — path leads directly to Fox’s summit.

Deep in morning shadow, the east side of the peak was cold! The ground was frozen, and heavy frost covered fallen leaves of chaparral. A few strenuous minutes and we were atop the peak, relishing the warmth of the sun and the panoramic view. Mt. Lukens, Josephine Peak, Strawberry Peak and Mt. Wilson loomed nearby. Further to the east, beyond Mt. Waterman and Twin Peaks, Mt. Baldy glistened white with a new coat of snow. Dressed for running, and damp from the climb, chill breezes hurried us from the summit.

Peak to peak the distance from Fox to Condor is over two miles. That’s what the map says, but on the ground Condor looks deceptively close. Several false summits amplify the deception, and many a hiker has been deceived. Even having viewed the route from Fox and climbed the peak before, I still did not fully appreciate the distance.

The scramble up Condor was a little longer than the hike up Fox. The peak has twin summits at very nearly the same elevation. We were curious which summit would have the register and found it on the more westerly summit. To do both Fox and Condor only added about an hour to our run.

Once down from Condor Peak it took about twenty minutes to hoof it over to the Trail Canyon Trail (13W03) junction. From here the trail drops about 3110 ft. in six miles. The grade of the trail is steeper than the Condor Peak trail, and a little more rocky and technical. Where the Condor Peak trail seeks the high lines, the Trail Canyon trail follows a creek and plunges into a deep riparian canyon.

Back at the car we marveled at what an enjoyable run it had been. The perfect weather and nearly ideal grade of the trails seemed to make the run almost effortless. It isn’t always that way.

Here’s a Google Earth image and Google Earth KMZ file of a GPS trace of the route.

Note: Although the Trail Canyon drainage is relatively small, it appears to have generated some sizable flash floods and debris flows. The canyon forms a huge southwest facing “rain catcher.” During Winter storms, the canyon wrings water from moisture laden wind as it is funneled into and up its slopes.

Runners winding their way up the final steep climb to the summit of 10,064 ft. Mt. Baldy during the 2007 Run to the Top race.

Despite an ongoing heat wave and excessive heat warnings, temps were surprisingly moderate for the 42nd running of the Mt. Baldy Run to the Top race. This year the men’s overall winner was Eric Martin in a time of 1:10:04, and the women’s overall winner was Brigid Freyne in a time of 1:30:41. For all of the results see the Run to the Top web site. Many thanks to the race organizers, volunteers, USFS, Mt Baldy Ski Lifts and the Mt. Baldy Fire Department for a great race!

Here are a few images from the race (Flash 8 required), a Google Earth image and Google Earth KMZ file (updated) of a GPS trace of the route.

Wally Waldron Limber Pine

A grizzled guardian of the San Gabriel Mountains, the Wally Waldron Tree stands defiantly astride an airy, rock strewn ridge, just below the summit of 9399 ft. Mt. Baden-Powell.

Perched on the brink of the mountain’s precipitous southeast face, the weather-sculpted Limber Pine is at an elevation and in an environment similar to the 4000+ yr. old White Mountain Bristlecone Pines. Burnished and hardened, the tree’s huge, gnarled roots anchor it firmly to the mountain, helping it to resist the whims of weather and time. The tree is estimated to be 1500 years old.

We had stopped to visit the tree part way through an approximately 23.5 mile loop from Islip Saddle. Our route had descended to South Fork Campground (4560′), before climbing back up to Vincent Gap and Mt. Baden-Powell. In a few minutes we would continue to Baden-Powell’s summit, and from there follow the PCT along the crest back to Islip Saddle. Here’s a Google Earth image and Google Earth KMZ file of a GPS trace of the loop.

Water Notes: The little stream on the Manzanita Trail about 1.5 miles from Vincent Gap was still running. The flow from Little Jimmy Spring was lower than normal, but still very reasonable. We did not detour to Lamil Spring.
