If you’re a bee in the Ahmanson Ranch area, your Fall menu of wildflowers is usually pretty sparse; particularly when the previous rain year has been below normal.
But life has a way of carving out a niche for itself in the toughest of circumstances. One plant you’ll find blooming in the oak grasslands of Ahmanson Ranch following a long, hot, dry summer is goldenbush. In the case of the title photo, it’s Palmer’s goldenbush.
Hikers, riders, and runners reveled in the unseasonably cool afternoon temperatures at Ahmanson Ranch (Upper Las Virgenes Canyon Open Space Preserve) yesterday.
According to the NWS, the high temperature of 75 degrees at Woodland Hills (Pierce College) was the lowest for the date on record. The temperature at the Cheeseboro RAWS didn’t reach the 70s until around 1:30 p.m., and finally hit 75 around 4:30 p.m. Earlier in the day, the station recorded 0.03 inch of light rain.
I took advantage of the cooler weather to do an out and back trail run from the Victory Trailhead to Cheeseboro Canyon. The nine mile run has an elevation gain/loss of around 1000′. Except for a couple of hills, it’s a relatively fast-paced route, particularly on the way out to Las Virgenes Canyon. There are two creek crossings in Las Virgenes Canyon. These dried up earlier this year, but in some years the crossings have enough water to get your shoes wet.
It’s not a good run to do when it’s hot, and in the Summer Ahmanson is almost always hot. In-the-sun temperatures are typically above 100 degrees, and sometimes reach 110 degrees or more. More than once I’ve encountered people on Ahmanson area trails that misjudged the conditions and were out of water. And sadly, dogs are especially susceptible to heat.
Here’s an interactive, 3D terrain view of the run. The map can be zoomed, tilted, rotated, and panned. For help controlling the view, click/tap the “?” icon in the upper right corner of the screen. Track and placename locations are approximate and subject to errors. Poor weather, and other conditions may make this route unsuitable for this activity.
Those that recreate at Ahmanson will recognize the title photo as East Las Virgenes Canyon, about 1.1 mile from the Victory Trailhead. This is where a trail/road to Lasky Mesa forks off the main road.
This afternoon I was running down a single-track trail at Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch), when I noticed a coyote on a parallel track across a small ravine. From time to time I would stop and watch the coyote, and from time to time it would pause and watch me. After a few minutes, it went its way, and I went mine.
Earlier in the run I’d been in the same area when a coyote, running at full speed, came blasting down a single-track trail. It turned into the brush about 30 yards in front of me. I’d seen similar behavior once before when one coyote was chasing another. In this case a hiker followed the coyote down the trail. In my experience, it usually take more than a simple encounter with a hiker to panic a coyote.
Update February 18, 2021. The coyote pictured on the right was in the same area as the coyote in the title photo. When I first encountered the coyote, it had just crossed the trail and was below me. For some reason it reversed its course and climbed to a viewpoint above me, and watched as I ran up the trail. After a few moments it ran back down hill, retracing its original course across the trail. It was one of the most well-conditioned coyotes I’ve seen out at Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch).
I have had a couple of unusual encounters with coyotes out at Ahmanson. One time, a coyote decided to run with me, as if on a leash.
From the top of the hill, the blue-sky view extended all the way to Saddle Peak and the Pacific. The gray-green chaparral was brittle and dry, and the grasslands sun-bleached. Rain was in the forecast, but for months, little had fallen. It was the day after Christmas, and I was near the northern border of Upper Las Virgenes Canyon Open Space Preserve. Fourteen years ago, nearly to the day, I had run to the same hill. That rain year had also been dry, and the area had looked much the same.
Today’s run had started at dawn at the Victory Trailhead. It had been cold in the canyons for the first few miles — in the low 30s — but eventually temps had warmed. I had run west in East Las Virgenes Canyon, taken a connector trail to Las Virgenes Canyon, and then run north on the Upper Las Virgenes Canyon fire road past Bell Canyon to “windmill hill.”
The hill is labeled with an elevation of 2124′ on the 1967 Calabasas topo map. The top of an old windmill has been placed on its summit. The windmill wasn’t there in 2006, and I wondered if it was from the infamous Runkle Canyon well. From the top of windmill hill I could see the high point of Upper Las Virgenes Canyon Open Space Preserve, a quarter-mile or so to the northeast.
Leaving windmill hill behind, I ran east down the hill, and then north along the fire road toward Albertson Mtwy. I was still debating whether to do the side trip to the Preserve’s high point. There was no path or trail to the high point, and the upper part of the slope was thick with brush. After running past the hill and nearly to Albertson Mtwy, curiosity finally got the better of me. I turned around and ran back to a place on the fire road where I could access the high point.
The side trip to the high point and back took about 20 minutes. After returning to the fire road, I continued down to the junction with Albertson Mtwy, turned left, and followed it west to a junction with an Edison powerline service road. This road meanders south through a rugged canyon, and then climbs up and over a prominent ridge with some spectacular sandstone rock formations.
After topping out on the ridge, the service road descends to the junction of the Sheep Corral and Cheeseboro Ridge Trails. Today, I followed the Cheeseboro Ridge Trail south to the Las Virgenes – Cheeseboro connector. Once back in Upper Las Virgenes Canyon, I retraced my route from earlier in the day back to the Victory Trailhead.
