Plan B: Barley Flats

Nearing the junction I debated what to do — turn left on a well-used trail and climb Strawberry Peak or continue straight on an abandoned, overgrown road and go to Barley Flats? If I continued on the road it would be my second bush-whacking adventure of the day. Earlier, I’d abandoned an exploration in upper Colby Canyon when frequent rifle fire made the canyon feel confined and dangerous. This adventure was my plan B.

Each time I’ve done Strawberry Peak from Red Box I’ve wondered about that overgrown old road. In the book The San Gabriels, John Robinson mentions that it was a Forest Service fire road built in 1926. It’s shown on the USGS 1934 Mt. Lowe and Mt. Wilson Advance Sheets connecting Red Box Gap and Barley Flats and then continuing to Charlton Flats, Chilao and the high country. Back then Angeles Crest Highway didn’t go to Shortcut Saddle, it turned at Red Box and went to the top of Mt. Wilson.

At the junction, I stepped over the rocks marking the left turn toward Strawberry Peak and started up the old road. After about five yards, I almost turned back. The trail was so overgrown it seemed nearly impassable. Yucca and whitethorn conspired to block the way, or at least make it too painful to proceed.

Having done my share of bush-whacking I’ve learned that it’s usually not as bad as it looks. With a little patience the determined hiker can usually find a tolerable way through. That was the case here, but not only was the trail overgrown, there were downed trees and limbs from the 2009 Station Fire, and several small rock slides and wash outs partially blocking the trail.

For 2.5 miles I kept repeating, “That wasn’t that bad. I’ll just see what’s around the next corner.” After nearly an hour and a half of seeing what was around the next corner — and almost turning back several times — I finally reached Barley Flats.

Like many places in the San Gabriels, Barley Flats has a colorful history. In the middle 1800s the site was a favored hideout of horse thieves and cattle rustlers. During the cold war it was one of the many Nike defense sites surrounding Los Angeles. More recently it was a Los Angeles County Sheriff’s Probation Camp and Retreat and today continues to be used as a staging area for LASD’s Air Rescue 5. Much of Barley Flats and the surrounding area was burned in the Station Fire.

Air Rescue 5 has conducted numerous life-saving missions in Angeles National Forest, including countless air ambulance evacuations from “nearly every corner” of Angeles Crest Highway.

Even before reaching Barley Flats I had decided to take an alternate route back to Red Box. Barley Flats sits on the divide between Upper Tujunga Canyon and the West Fork San Gabriel Canyon. Doing a loop through West Fork sounded a lot more appealing than running the thorny gauntlet back to Red Box on the old road.

It took about one-third of the time to run three miles down paved — and brush-free — Barley Flats Road as it had to bushwhack from Red Box to Barley Flats. There were a few hunters out on Barley Flats road, but all had their rifles shouldered. Since leaving Red Box I had heard only one very distant rifle shot — a big change from the far too frequent rifle fire in Colby Canyon.

From the intersection of (gated) Barley Flats Road and Angeles Crest Highway it was only about 0.7 mile over to Shortcut Saddle. At Shortcut I picked up the Silver Moccasin Trail. As I began to run down the trail toward West Fork, I reached around with one hand and lifted my pack. How much water remained?

The plan was to run down to West Fork, get water, and then run up the Rincon-Red Box fire road to Red Box — completing a loop. The spring at West Fork is usually reliable, but with the drought I couldn’t be 100% sure. Nearby Mt. Wilson was recently forced to close its restrooms and turn off the water spigots used by hikers and runners because of insufficient water.

I was surprised to find the spring was running as strong as it had been in early July during the Mt. Disappointment Endurance Runs. Water was not going to be an issue on the five mile run up to Red Box.

Glimpse of Autumn

I was running in the hills along the western margin of the San Fernando Valley and reveling in the Autumn-like weather. The hills were parched, brown, and the soil dessicated. In 128 days it had not rained.

An area of low pressure was producing some clouds and even a little rain in some parts of Los Angeles County. The last time it had been this cool in the afternoon was in mid-June. The pleasant temperature was a welcome change from the 80s, 90s and 100s of Summer.

Precipitation from the 2015-16 Godzilla El Nino fell short of expectations, with Downtown Los Angeles only recording 65% of normal rainfall and the drought continuing into its fifth year. How long would we have to wait  until we received widespread rainfall?

At the moment the expectation is for ENSO Neutral conditions to prevail this Winter. Neutral conditions give forecasters little leverage on which to base their Winter outlook, but based on last year’s Southern California precipitation forecasts, we didn’t have much leverage then either.

With a warming planet, we appear to be in a new regime. Forecasts based on 1950-2000 analogs may no longer be applicable. As of September 15 the Climate Prediction Center’s Precipitation Outlook for Southern California for December, January and February is the equivalent of flipping a three-sided coin.

We may just have to wait and see what the Winter brings.

Regrowth near Grassy Hollow following the 1997 Narrows Fire

Each time I’ve run the segment of the Pacific Crest Trail between Inspiration Point and Vincent Gap I’ve been curious about a cluster of young pines in a burned area near Grassy Hollow. The trees appear to be older than similar areas of regrowth along the PCT between Mt. Baden-Powell and Little Jimmy Spring, which burned in the 2002 Curve Fire.

In turns out the area near Grassy Hollow was burned in the 18,186 acre Narrows Fire in 1997. That would make these trees about five years older than the Curve Fire regrowth.

Considering our huge precipitation deficit in Southern California over the past five years, the young trees in the Curve and Narrows fire areas seem to be doing surprisingly well.

Malibu Creek State Park Redwoods: Fighting the Drought

Epicormic sprouts along the trunk of a drought-stressed coast redwood in Malibu Creek State Park. July 3, 2016.

Recently, I revisited the coast redwoods along Century Lake in Malibu Creek State Park . Several months ago I’d been disheartened to find many of these trees severely stressed by our five year drought. Several of the trees had lost most of their foliage. Based on my own photos and those from Google Earth, the trees had rapidly deteriorated in just a few months.

I started at the the westernmost redwood near the junction of the Forest Trail and Crags Road and worked east along the Forest Trail. I expected to see a decline in the trees since my last visit, but surprisingly that wasn’t the case. If anything the trees looked they might be doing a little better.

From west to east I counted about 16 trees or clonal clusters of trees. Of these, the trees on the bank of Century Lake appear to be the most severely impacted. At least one tree, with poison oak growing up its trunk, may have died.

A common drought response is for a plant to reduce its foliage. The size of its leaves may be reduced and leaf shape modified to reduce water loss. In some cases trees will become dormant and lose their foliage. Trees may also enter seasonal dormancy early and the period of dormancy may be extended.

It’s been my experience that trees respond to severe water stress in a manner similar to losing their foliage in a fire. One redwood that had appeared to be dead in March, now has new epicormic sprouts over the length of its trunk.

Another mechanism by which a redwood may survive the drought is by clonal sprouting from buds in its basal burl. It is common for coast redwoods to have numerous basal sprouts and sometimes these develop into additional trunks.

The easternmost redwood is of particular interest because it appears to be naturally-germinated. For now it is stressed, but surviving.

The survival of these trees is not only dependent on the drought, but climate factors such as temperature and fog frequency and persistence. Only time will tell if some of the trees are resilient enough to survive.
