Warrior’s plume (Pedicularis densiflora) along the Cheeseboro Canyon Trail, one of the areas burned in the November 2018 Woolsey Fire.
With this rain season’s abundant rainfall, displays of wildflowers will be more extensive than usual and of greater variety — both inside and outside the Woolsey Fire burn area.
This afternoon’s run was to the Cheeseboro Remote Automated Weather Station (RAWS). The station is perched on the ridge between Las Virgenes Canyon and Cheeseboro Canyon, along the Cheeseboro Ridge power line service road.
It is about 5 miles from the Victory Trailhead of Upper Las Virgenes Canyon Open Space Preserve (formerly Ahmanson Ranch) and one of many good runs from that trailhead into the Cheeseboro – Palo Comado Canyon area.
Runs in the Ahmanson Ranch area are especially scenic at the moment. Above average rainfall has produced lush green growth in the oak grasslands following the Woolsey Fire. Many of the oaks are beginning to sprout new leaves and poppies and other wildflowers are beginning to bloom. Today there was a nice show of poppies in Las Virgenes Canyon at the connector leading to Cheeseboro Ridge and Cheeseboro Canyon.
Operated by the BLM and NPS the Cheeseboro RAWS (CEEC1) has been in service since September 1995. The station was in the area burned by the 2005 Topanga and 2018 Woolsey Fires and was active throughout each event.
Following are some of the extremes recorded by the station:
• Highest hourly temperature was 115 °F on July 7, 2018.
• Lowest hourly temperature was 32 °F on December 12, 1998.
• Maximum hourly wind speed was 37 mph on October 22, 2007.
• Maximum wind gust was 92 mph on January 6, 2003.
• Maximum daily precipitation was 5.01 inches on February 12, 2003.
So far this rain year (July 1 to June 30), 15.67 inches of rain has been recorded by the station.

Rounded a corner running down the Lower Stagecoach Trail, above Corriganville, and was suddenly immersed in a sea of orange.
The area was burned in a potentially dangerous fire, the Peak Fire, that started along the 118 Frwy on November 12, 2018, while the Woolsey Fire was still being fought. The fire threatened homes in the eastern Simi Valley and Box Canyon, but was aggressively attacked by firefighters and quickly knocked down.
Shooting stars (Dodecatheon clevelandii ssp. patulum) love wet weather, but produce capsules that help protect their seeds should the weather turn suddenly dry.
These shooting stars are on a new section of the Loop Trail at Sage Ranch Park. The Loop Trail was rerouted due to the ongoing cleanup at the Santa Susana Field Lab.
Bigpod Ceanothus is normally the first of the Ceanothus species in the Santa Monica Mountains to bloom each year. It is a foundation species in the range and can be found along most trails. These were along Fire Road 30 (Temescal Ridge Fire Road) near the beginning of a run to Trippet Ranch.
In some years it seems every shrub in the chaparral is a big pod Ceanothus and the hillsides are carpeted in white. Along a trail thick with the blossoms you may notice a subtle earthy fragrance with a spicy edge. On that same trail in the Summer, you may be startled by a loud “Pop!” when a heated pod explodes, releasing its seeds.
Yellow seems to be the predominant color of late-summer and fall wildflowers in Southern California. In addition to the bush Senecio pictured above; rabbitbrush, goldenbush, tarweed, telegraph weed and common sunflower come to mind.
From a recent run of the Trippet Ranch loop, with a side trip to Temescal Peak.
