The initial burn severity estimate is based on a Burned Area Reflectance Classification (BARC) derived from satellite data before and after the fire. In the map above the burn severity classes are high (red), moderate (orange) and low (yellow). Note that areas within the fire perimeter that are not included in these classes may still have burned. Also note the fire was still burning when this assessment was made.
GPS tracks of the Backbone Trail and some other trails in the region have been added. Trail and placename locations should be considered approximate.
The Google Earth image above shows a recent perimeter for the 2018 Woolsey Fire along with GPS tracks of the Backbone Trail and some other trails in the region. The Hill Fire perimeter and 2013 Springs Fire perimeter (purple area) are also shown. Trail and placename locations should be considered approximate. Here is a larger version of the map.
The perimeter was was downloaded from GEOMAC and timestamped November 18, 2018 at 5:59 a.m. If the timestamp of the perimeter of the displayed map doesn’t match, try refreshing/reloading this page. The perimeter has been refined and the acreage is a slightly less than previously specified.
It’s been nine years since the Station Fire burned 160,577 acres in Angeles National Forest. The Red Box – Bear Canyon – Gabrielino loop is a long time favorite adventure run that I’ve enjoyed doing many years before and after that 2009 fire.
The loop was the first I did when the area reopened in May 2011. The trails were in poor shape — overgrown and damaged from flash floods. The notorious fire-follower Poodle-dog bush had flourished in the wake of the fire and was particularly bad along the Gabrielino Trail between Switzer’s and Red Box. Thinking I was “immune” to the plant, I brazenly plowed through it, and as a result spent several inflamed nights trying to sleep in a reclining chair.
Each year Bear Canyon and upper Arroyo Seco recover a little more. Poodle-dog bush is in decline and in many areas nearing the end of its life-cycle. The chaparral, bay trees and oaks are all recovering; and the bigcone Douglas-firs that survived the fire have become more fully-foliaged.
This year Bear Canyon was a little drier than last. The creek was a trickle, disappearing in the sand in some areas and creating small pools in others. The path in the upper part of the canyon, above Bear Canyon Camp, was better defined, but still tricky to follow in some spots.
With the dry conditions, most of the poison oak had already turned red. It was easy to spot, but difficult to avoid. The “stinging nettle” creek crossing higher in the canyon wasn’t as overgrown as last year, but I still managed to brush against a plant or two.
Bear Canyon ends at Arroyo Seco, downstream of Switzer Falls. After turning upstream on the Bear Canyon Trail, I hadn’t run far when I encountered a couple of mountain bikers. They asked me, “is this the trail to JPL?”
This wasn’t the first time that I’d encountered misplaced riders or hikers on this section of trail. Some get misplaced looking for the falls and others mistakenly follow the Bear Canyon Trail down into Arroyo Seco instead of continuing high in the canyon on the Gabrielino Trail. Because of the completion of the restoration of the Gabrielino Trail there were a few more riders on the trail than usual.
The smoke in the Owens Valley was as thick as PCH fog, and I wondered if it would extend into the higher elevations of the Sierra.
From Whitney Portal Road I couldn’t see any of the ridges on Lone Pine Peak and the visibility at the bottom of Horseshoe Meadow Road wasn’t much better. Gradually, as I drove up one long switchback and then another, the smoke thinned. At Horseshoe Meadow the sky in the direction of the crest was a decent Sierra blue, but smoke still spoiled the views down the canyons and over the valley.
As usual, I parked at the equestrian and overflow parking area for the New Army Pass Trail. From here, the start of the Cottonwood Pass Trail is a 5 minute walk SSW through the trees and downhill. I prefer to do the loop clockwise, going over Cottonwood Pass first, and then New Army Pass later in the run. Late season, I’ve also done the loop using (old) Army Pass, but that is more of a mountaineer’s route and is often blocked by snow and ice.
New Army Pass is fairly high — 12,300′ — and the east side is quite steep near the top. Depending on the year, snow and ice can be an issue, even in mid-summer. When doing the loop clockwise, confirm in advance that New Army Pass will be passable with your level of experience and the equipment you’ll be carrying.
