Google discontinued its Google Earth API/Plugin in January 2017. That technology was used on PhotographyontheRun.com for 3D visualizations of trail runs, fire data, and other data.
I’ve been looking at alternatives since then, and have recently implemented an interactive viewer using the CesiumJS and Cesium ion components of the Cesium 3D Geospatial Platform. No browser add-on or plug-in is required. The viewer uses the Cesium World Terrain high-resolution global terrain tileset, with resolutions to 0.5 meter. The West Coast of the US is one of the areas covered by this resolution.
Following are example 3D visualizations of some of my recent runs. The views are interactive and can be zoomed, tilted, rotated and panned. Click/tap the “?” in the upper right corner for help manipulating the scene. Mileages and elevation gains/losses are approximate.
The initial view is of San Gorgonio Mountain from the northeast, showing the trail to the summit and the Sky High Trail. The large cirque held one of several glaciers on San Gorgonio Mountain. The GPS track is from a run in September.
The view above is from the John’s Meadow Trail, a circuitous trail that winds its way through a less-traveled part of the San Gorgonio Wilderness.
The prominent canyon in the photo is home to Forsee Creek. During the last ice age, it held one of San Gorgonio’s small glaciers. I’d just crossed the Forsee Creek a few minutes before, and in a few hours would run past its source high on the crest — Trail Fork Springs.
The peak at the head of the canyon is East San Bernardino Peak (10,691′). Its summit marks the crest of the divide and the location of the San Bernardino Peak Divide Trail. That’s where I was headed, but the path would be anything but direct.
From the Forsee Creek crossing at 7270′, the John’s Meadow Trail climbs about 1000′ in 2.3 miles to join the Divide Trail at “wheelbarrow junction,” about 5 miles west of East San Bernardino Peak. From that point I worked up the popular and scenic Divide Trail, visiting Limber Pine Bench (9330′), Washington Monument (10,290′), and San Bernardino Peak (10,649′) along the way to East San Bernardino Peak.
Using this roundabout — but very scenic — route, it took me about the same time to reach San Bernardino Peak from the Forsee Creek Trailhead as it does to do San Gorgonio Mountain from the South Fork Trailhead. From San Bernardino Peak it’s a little less than a mile to East San Bernardino Peak and from there only about 0.75 mile to the lateral to Trail Fork Springs.
From the westernmost Trail Fork Springs junction with the Divide Trail the theme was downhill, downhill, and more downhill — about 3800′ of downhill over 6.7 miles.
The running on the Forsee Creek Trail was generally very good. I was glad I did the loop counterclockwise. The John’s Meadow Trail and its extension are enjoyably primitive — they appear to be “use” trails that have evolved over time. On the other hand, the Forsee Creek Trail is a constructed trail. It was designed as a pack trail, so is generally well-behaved. Great for going down, but a long haul up with a heavy pack!
Note: Water is generally more reliable and accessible on the John’s Meadow Trail than on the Forsee Creek Trail. Trail Fork Springs and Jackstraw Springs are seasonal water sources that may not have water. Check with the Mill Creek Ranger Station for the current conditions and more info.
One of the things I’d been curious to see when running the Kodiak 50K in mid-August was how the summit snow band on San Gorgonio Mountain was holding up. The answer turned out to be fairly well. Now, a few weeks later, I was back on Gorgonio, chugging up the South Fork Trail, and on my way to see if any snow remained on the mountain.
Runoff from thunderstorms during the week had left the trail rocky and rutted. From the views of the mountain I’d glimpsed from the trail, I wondered if the rain had also washed away any remaining patches of snow.
In addition to that question, I also want to follow up on my earlier “field checks” this Summer and see how much water there was in Dry Lake, and if any snow remained in the avalanche debris above Dry Lake.
I was about a quarter-mile from the Dry Lake – Dollar Lake junction at South Fork Meadows, making decent time, when I heard footsteps behind me. I stepped to the side so he could pass, and we talked as we worked up the trail. Kevin said he’d been climbing in the Sierra just about every weekend and was really well-acclimated.
I asked him what route he was doing to the summit, and he said the Dry Lake route. I told him I was doing the Dollar Lake Trail route up and the Dry Lake route down. He was clearly moving faster than me and said he was shooting for a time of 4:20 to the summit. I mentioned the Dollar Lake route was shorter and faster, and depending on the number of stops for photos, I expected to get to the summit in around 3:45. We talked about some Sierra peaks and being in the mountains, and after a couple of minutes, he began to pull away.
The early morning temperature had been a little more chilly than my earlier trips up Gorgonio this Summer. I debated pulling on my sleeves, but by the time I was in the sun on the Dollar Lake Trail, the temperature had warmed to a comfortable 50-something — perfect for ascending the peak.
The summit of San Gorgonio was a very busy place when I arrived. I’d estimate 40-50 people were on or around the summit. Most were part of one huge group that had come up Vivian Creek.
Kevin caught up to me on the descent of the Sky High Trail. We’d both made the summit within a couple of minutes of our projections, leaving little doubt that the Dollar Lake Trail is the fastest route to the summit from the South Fork Trailhead.
I didn’t see any snow remaining in the avalanche debris above Dry Lake. The lake itself was in great shape, and the streams at South Fork Meadows were flowing nearly as vigorously as they had been a month ago.
Update November 26, 2019. A small amount of snow from the 2018-19 season has survived on San Gorgonio Mountain until the first persistent snow of the 2019-20 season! Copernicus Sentinel satellite imagery from November 17, 2019 showed small patches of snow in two areas. The first winter storm of the season brought snow to the mountains a couple days later, and more snow is expected over the Thanksgiving holidays.
Working up the rocky trail, I looked to my left across the broad valley to San Gorgonio Mountain. There was still a narrow strip of snow near its summit, bright white in the morning sun.
I was about 5.5 miles into the Kodiak 50K and nearing the top of 9952′ Sugarloaf Mountain. There wasn’t any snow here, but the morning had been cool — at least by Southern California summer standards.
This was my sixth time running Kodiak. The first four times were at the 50M distance, and this year and last, I’d opted for the 50K. There have been a lot of changes in the Kodiak Ultra Marathons since the first 100M & 50M were run in 2013.
Initially held in late September, the event moved to an August date in 2017. 50K options were added in 2015. For the first three years the Kodiak courses were run in the counterclockwise direction. In 2016 the direction switched to clockwise and then alternated direction each year through 2018. This year the direction was the same as in 2018 — clockwise.
The general idea has remained the same. The 100 milers run a loop around Big Bear Lake. On the way, they ascend Sugarloaf Mountain, and also descend thousands of feet into the dank depths of Bear Canyon. The 50 milers run from the north side of the lake to the Finish, climbing either the Siberia Creek Trail if the course direction is counterclockwise, or Sugarloaf Mountain if the course is run clockwise. The options for 50Kers have varied from year to year.
This year the 100M start time was moved to 6:00 p.m. This put 100M runners beginning the descent into Bear Canyon between about 8:00 p.m. and 10:30 p.m. — a much cooler time of day. The trade-off was that they would be doing the 3000′ climb up Sugarloaf Mountain with about 67 miles on their legs, and many of the runners would run into a second night.
There were two notable changes in the Kodiak 50K this year. One adjustment is that it started two hours earlier — at 6:00 a.m. The other is that it was a couple of rocky miles longer than last year. The mileage was added on the descent of Sugarloaf — with runners looping down Wildhorse Meadow Road instead of retracing their route on the Sugarloaf Trail. My watch recorded a distance of about 34.5 miles and corrected elevation gain of about 6800′.
Because of the change in the 100M and 50K start time, we were ahead of many of the 100M and 50M runners, but we did get to see the 100M leaders flying down Sugarloaf.
The weather was cool in the morning and warm in the afternoon. At Big Bear Airport the overnight low Friday night was 37°F and the high on Saturday was 77°F. With the clear skies, it was hot on exposed, south-facing trails. The Converse RAWS (5618′) recorded a high (inside a ventilated instrument housing) of 84°F; however the “fuel temperature” of a pine dowel in direct sun hit 106°F. In my experience, the fuel temperature is a better indicator of the temperature runners might encounter on sun-baked sections of trail.
My run went well. There was no repeat of the leg cramps I experienced near the end of this year’s ANFTR/Mt. Disappointment 50K. This 50K was longer, had more elevation gain, was at higher elevation, and was generally more technical, but my legs behaved the entire time. That’s the riddle of Exercise-Associated Muscle Cramps (EAMC). Sometimes you get leg cramps and sometimes you don’t. In this race I made sure that I stayed well-hydrated and fueled. I also used poles on the steeper climbs.
This was one of those races that I could just run and enjoy. It was great to talk with Diana, Gloria and Greg along the way. The runners you meet during races are often very accomplished and usually have some unique stories to share!
Many thanks to Kodiak Race Director Susie Schmelzer, Course Director Harald Zundel, and Communications Director John Emig and to Team Kodiak, all the volunteers, sponsors, Bear Valley SAR, HAM operators, medical personnel, City of Big Bear Lake, US Forest Service, Big Bear Trails Foundation, RIM Nordic and Open Air Big Bear, and everyone that helped put on the event.
The weather was Southern California perfect. Shorts and short-sleeves were the dress of the day. Winds were light, no thunderstorms were in the forecast and no large wildfires polluted the air. Although temps in the valleys were nearing 100 degrees, the weather on the summit of 11,499′ San Gorgonio Mountain was altitude-conditioned bliss.
I’d spent about 15 minutes enjoying the summit, then run back down the Summit Trail. Turning left onto the Sky High Trail, I continued a keyhole loop that had ascended the South Fork Trail, Dollar Lake, and San Bernardino Divide Trails. Altogether, the route was about 21 miles long and the approximate elevation gain/loss was 4700′.
From the start of the run, the effects of the wet 2018-19 Winter and big snowpack were everywhere. Wildflowers bloomed in profusion, seeps and small streams greened the landscape, and grasses and ferns grew thick beneath the trees. The roar of the streams at South Fork Meadows left little doubt as to what kind of Winter it had been.
On the way up the Dollar Lake Trail, I’d seen elongated patches of snow in the chutes along the crest. While there was no snow directly on the trail between Dollar Lake Saddle and the summit, there was more snow than usual on the north side of the peaks.
But there was snow on the Sky High Trail. Topping out at over 11,300′, the Sky High Trail is one of the most spectacular trails in Southern California. I marvel at its airy location every time I run it. Near the top of the trail, I’d crossed a small patch of snow and thought, “Well, at least there was a little snow on the trail.”
A little disappointed, I’d put my poles away and continued running down the trail. At around 11,100′ I rounded a corner and surprise, surprise — there was a much larger patch of snow on a southeast-facing section of trail. It was about 100 yards across and steep enough that a fall would be a bad idea. Fortunately, the snow conditions were perfect. A few hikers had recently traversed the snowfield, and I followed in their footsteps.
However, that wasn’t the last of the snow. At an elevation of about 10,200′, not far past the C-47 crash site, the trail crosses a long chute that extends nearly to the top of Gorgonio. The snow in that chute had melted just enough that a thin strip of trail was exposed.
Thinking that had to be the last of the snow, I continued the traverse to Mineshaft Saddle (9936′) and began the descent of the Dry Lake Trail. Once past a rocky section of the trail, I picked up the pace, energized by the increased oxygen at lower elevation. Enjoying the downhill, I descended into an area of converging chutes and gullies, when the path through the lodgepole forest abruptly ended.
The trail was obliterated. Large trees were ripped from the ground, broken, tossed, and piled up as if they were matchsticks. Underneath the debris were mounds of dense, icy snow — the remnants of an avalanche. This report on SoCalSnow.org includes photos of an avalanche in February 2019 on the north face of San Gorgonio and mentions previous avalanches.
That snow, at an elevation of about 9400′, had finally been the last on the trail. Because the compressed snow is effectively a big block of ice, it could be around for a while.
In the area of the avalanche, the Dry lake Trail enters a large area of rocky rubble that extends into the Big Draw. According to the Dibblee Geologic Map for San Gorgonio Mountain, this rubble is glacial till, produced by the largest of several pocket glaciers that existed on San Gorgonio Mountain, Shields Peak, and San Bernardino Peak.
Continuing down the trail to Dry Lake I saw where some of this season’s meltwater had gone — for the first time since 2011, Dry Lake was full in late July.
Last Saturday’s run was so enjoyable that yesterday I went back to Gorgonio and did it again. As might be expected during a Southern California Summer heatwave, the snow on the Sky High Trail, and elsewhere, is melting fast and won’t be around for long.
Here are a few photos taken along the way. The album includes photos from both the July 27 and August 3 runs. A couple of photos from a run on September 7 were also added.
The out and back trail run from the Chula Vista parking area on Mt. Pinos to Mt. Abel (Cerro Noroeste) is a long-time favorite. It combines subalpine summits, beautiful pine and fir forests, and a unique flora with uncrowded trails that are fun to run and explore.
The basic out and back to Mt. Abel (Cerro Noroeste) with a stop on the way back at Sheep Camp for water is around 14 miles with an elevation gain/loss of about 3400′. The side trips to Sawmill Mountain and Grouse Mountain are short and add about 0.75 mile to the distance and around 250′ to the elevation gain.
As in other areas of Southern California, the wet 2018-19 Winter has resulted in an abundance of wildflowers in the Mt. Pinos region. Paintbrush, mariposa lily, larkspur, penstemon, lupine, phlox, iris, yarrow and many other plants are blooming in profusion. Limber pines in the area are full of cones and the spring at Sheep Camp is flowing well.
