The posts Boney Mountain - Big Sycamore Canyon Circuit and Boney Mountain Western Ridge & Loop describe two routes that ascend the north side of Boney Mountain -- a circuitous eastern ridge route, and a more difficult western ridge.

These two routes can be combined into an adventurous loop that starts and ends at the junction of Danielson Road and the Old Boney Trail. The loop, with no side trips, works out to about 4 miles. Add in the 2.5 mile approach from the Wendy Drive trailhead, and the total distance for the course is about 9 miles, with an elevation gain of a bit over 2000 ft.

I did the loop counterclockwise -- up the western ridge and then down the eastern. The New Year's weather could not have been better. Dense fog clung to the coast, but a brisk offshore breeze kept inland views crystal-clear. On the way up the western ridge I couldn't resist doing a short detour to climb one of the crag's appealing summits.

At the top of the western ridge, I briefly debated doing Tri-Peaks and Big Dome, but was hoping to make it home by noon, so skipped those side trips.

With gravity on my side, the run down the eastern ridge was not nearly as gnarly as I thought it might be. I was running in Inov-8 Roclite 305s -- nimble shoes with a fell running heritage. Mine weigh only 21.1 oz./pair (US 9.0) and were particularly well-suited to the rough terrain.

This climb and adventure run was a great way to start the New Year -- and I did make it home in time for lunch with my wife!

Here's a Google Earth image of a GPS trace of my route.

Two routes are commonly used to climb the rugged north side of Boney Mountain. One route ascends a ridge to the east of the Danielson cabin site, and the other a rocky ridge to the west of the site. Today, I was planning to do the western ridge, and then continue up and over Tri-Peaks to the Chamberlain segment of the Backbone Trail.

We stopped for a few moments at the river crossing, where water stood in pools waiting for Winter rain. Instead, cold air flowed down its course, cool and refreshing. From this point there would be little shade. Rarely cold, the climb out from the West Fork San Gabriel River to Shortcut Saddle is often warm, and sometimes debilitating.

Scruffy clouds clung to the mountain ridges and summits, confirmation that a weak cold front was moving through the area, cooling temperatures and stirring up the wind. The forecast for the Santa Monica Mountains National Recreation Area had mentioned 25 to 35 mph winds with gusts to 60 mph. So far the weather in Pt. Mugu State Park had been nearly perfect -- breezy and little chilly, but without the impenetrable winds that can take all the joy out of running.

When I woke to the rumble of thunder, rain pounding the roof, and wind roaring in the trees, I wondered if a planned run of the Boney Mountain Half Marathon course with John Dale was going to turn into an epic. Radar and satellite imagery showed subtropical moisture streaming in from the southwest, producing bands of showers and thunderstorms. Things don't always look as bad at the trailhead as they do on weather radar, so I grabbed my gear and headed for Wendy Drive.

The scat appeared to be a day or two old, and was much bigger than a coyote's. It was full of fur and could only be from one animal -- a mountain lion. The spot had been used before, and it probably wasn't a coincidence that this was one of the few points along the trail with a good view and nearby cover. I looked into the brush and wondered if unseen eyes looked back.

It's fun to link together several trails into a loop, and it's even more fun when the trails are single-track, or at least have a single-track flavor. The Boney Mountain - Big Sycamore Canyon circuit links together segments of more than ten trails and roads in Rancho Sierra Vista/Satwiwa and Pt. Mugu State Park. The route is characterized by airy ridges, steep climbs, wide-ranging views, towering rock formations, and one of the best downhill running segments in the Santa Monica Mountains. Today's run expanded the loop, adding even more single-track trail -- and elevation gain.

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.

Maybe 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.

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.

Lowland blues got you down? Are you repeatedly measuring the elevation gain to your third floor office? Are you beginning to think faux pine tree cell towers aren't that ugly? Do you gaze longingly at distant mountains and then realize you're looking at a billboard?

When I feel that way, one of the close-to-home hikes/runs that satiates the alpine craving is the Falls Creek loop on Mt. San Gorgonio. The 'Falls Creek up, Vivian Creek down' route has been a high mountain favorite of mine for a number of years. It is as rigorous as it is beautiful. About 24.5 miles long, it gains approximately 6600' on the way to the 11,499' summit of San Gorgonio...

If you spend much time in the mountains, sooner or later you're going to get caught in a severe thunderstorm. I don't mean you're going to hear a little thunder and get a little wet. I mean you're going to find yourself in the middle of a heart pounding, ear splitting, ozone smelling, sense numbing storm that drenches you through and through and wrings the nerves from your body.

Having been caught in such thunderstorms while climbing in Yosemite, running in the San Gabriels, and running at Mt. Pinos, I do my best to avoid the beasts. Sometimes, it is not an easy thing to do.

It isn't unusual for snow to persist on New Army Pass (12,300') well into July. Strong northwest winds, following in the wake of blustery Winter storms, blow freshly fallen snow over the crest and into this cirque, forming cornices along its lip, and dense slabs of wind-ground snow in it's lee.

That's why the July 1 Sequoia & Kings Canyon National Park Trail Conditions report for New Army Pass seemed plausible. It read, "The top of the pass has an 30 foot snow wall - ice axe recommended."

The reported trail conditions are a compilation of reports from the field, and are not always up-to-date. Having been over the pass a number of times, and in a variety of conditions, I thought that we would probably be able to bypass any remaining patches of snow without needing an ice axe. Worst case, if the pass looked dicey, we could use Cirque Peak or some other alternative route to attain the crest.

We need not have worried. While there was snow in the cirque, and in a couple of places along the trail near the top of the pass, the trail was completely clear. Even so, it was a good excuse to do the 21 mile Cottonwood loop counterclockwise -- the reverse of my usual circuit -- climbing up New Army Pass from the Cottonwood Lakes side, and then running down into Rock Creek basin.

Now that I've done the loop in both directions, I think I prefer the clockwise circuit. The 9 miles of running from New Army Pass down through the Cottonwood Lakes basin is generally better than the running down from Chicken Spring Lake and Cottonwood Pass. Also, there's more downhill on some sandy sections of trail between Chicken Spring Lake and Rock Creek. The tradeoff is you give up the nice downhill into Rock Creek basin, and near the end of the loop have a mile or so of annoying uphill.

Here's a Google Earth image, Google Earth KMZ file, and an elevation profile of a GPS trace of the route. (The elevation profile was generated using SportTracks.)
