The north side of San Gorgonio Mountain was closed in June 2015 when the Lake Fire burned approximately 31,359 acres of forest, chaparral, sage, pinyon and Joshua tree habitat at elevations ranging from about 10,700′ to 5350′. As a result of the determined efforts of firefighters, only one residence and some remote outbuildings were lost.
Of the 30,487 acres reviewed by the Burned Area Emergency Response (BAER) team 4,327 acres (14%) were categorized as Unburned; 17,100 acres (56%) as having Low soil burn severity; 8,420 acres (28%) as having Moderate soil burn severity; and 640 acres (2%)with High soil burn severity. (Note that soil burn severity isn’t necessarily synonymous with fire intensity and fire effects such as tree loss.)
I’d been keeping an eye on the Alerts & Notices section of the San Bernardino National Forest web site to see if the Lake Fire closure order would be renewed. I was curious to see the extent and impacts of the Lake Fire and how the area was recovering. Plus, the Dollar Lake – Dry Lake keyhole loop is an outstanding trail run — one of the best in Southern California. In addition to climbing San Gorgonio Mountain (11,499′), it encompasses some of the most scenic areas on the peak.
The area’s trails reopened July 20. The weekend prior to the reopening San Gorgonio Wilderness Association volunteers worked on the South Fork and Dry Lake Trails, clearing a number of large trees, removing debris and other hazards and improving the trail tread.
A week and a half after the opening I pulled into the South Fork parking lot on Jenks Lake Road, excited to get on the trail. There was a slight chance of thunderstorms in the forecast, and I hoped to be off the summit and on my way down by 10:30 or 11:00.
Most of the run is in the San Gorgonio Wilderness and a wilderness permit is required. Check a map, but the general sequence of trails is the South Fork Trail, Dollar Lake Trail, Divide Trail, Summit Trail, Sky High Trail, Dry Lake Trail and then back down the South Fork Trail to the trailhead. This Google Earth image shows the western part of the Lake Fire burn area in relation to San Gorgonio Mountain and some of the area’s trails.

burn area and FRAP fire history. The fire database showed two previous fires in the area -- a fire in 1950 (309 acres) and in 1951 (1412 acres). The yellow trace is the GPS track of my run.
Crown-sprouting California black oaks along the South Fork Trail about 0.5 mile from the trailhead. July 29, 2017.
Mix of burned and scorched trees below Horse Meadow about 1.1 mile from the South Fork trailhead. July 29, 2017.
It was a close call at Horse Meadows, but the cabins and most of the trees appeared to be OK.

Coyote tobacco along the South Fork Trail. The flowers of the plant were open in the morning and closed in the afternoon. The plant changes the time of day the flowers are open to protect itself from hungry caterpillars
that hatch from eggs deposited by pollinating moths.

Chinquapin produces a nut, several of which are encased in each thorny burr.

Continuing on the Divide Trail above the Little Charlton - Jepson saddle. At this point the elevation is about 10, 600' and it's about two miles to the summit of San Gorgonio.

The final section of trail leading to the summit of 11, 499' San Gorgonio Mountain, the highest peak in Southern California. There was only one other person on the summit at 10:45 a.m. He had ascended the peak via the Vivian Creek Trail.
San Jacinto Peak (10839') from the Sky High Trail on the south side of San Gorgonio Mountain.
Cumulus clouds were already beginning to develop over San Gorgonio Mountain and San Jacinto Peak when I left Gorgonio's summit at 10:45 a.m. and by 1:00 p.m. or so it was mostly cloudy. Thunder rumbled in the distance a couple of times.
These lodgepole pines along the Fish Creek Trail were previously killed by a bark beetle infestation. Some of the dead trees were burned in the Lake Fire.

On this particular run I also wanted to check out the Fish Creek Trail and the “use trail” down to Lodgepole Springs and Dry Lake, so rather than continuing down the Dry Lake Trail from Mineshaft Saddle, I turned right (east) and followed the Fish Creek Trail to Fish Creek Saddle.
There were some downed trees and a lot of fire debris on the Fish Creek Trail. Extra care was required and I probably hiked as much of it as I ran. As I worked toward Fish Creek Saddle I could not tell how much of the canyon leading down to Lodgepole Spring had burned. The slopes on the southwest side of Grinnell Mountain had burned and some areas along the Fish Creek Trail had burned as well. Whether I descended to Lodgepole Spring from Fish Creek Saddle or returned to Mineshaft Saddle would be a judgment call.
Arriving at Fish Creek Saddle I was glad to see the forest was intact. The path down to Lodgepole Spring looked promising, but had not been used in some time. As it turned out most of the trees along the path had not burned. In places, runoff from the burned slopes above had resulted in some erosion and small flows of sandy soil. There were also the usual downed trees, but other than being a little challenging to follow, the path was generally OK.
I was nearly off the trail when the “chance of thunderstorms” forecast materialized into threatening gray clouds, a few sprinkles, and a couple of rumbles of thunder.
