Snow-Covered San Gabriel Mountains From Lasky Mesa

Snow-covered San Gabriel Mountains from Lasky Mesa in Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch)

It had rained another inch overnight, and my shoes were soaked from the wet grass along the trail. Seeking some relief from the 20 mph northwest wind, I descended a single-track trail to an old paved road east of the ranch house on Lasky Mesa.

Motivated more by staying out of the wind than anything else, I did two sets of hill repeats on different sections of the road. Then, on tired legs, I jogged up to Lasky Mesa and was greeted by an Arctic blast. The temperature had dropped to the mid-40s, and the wind was blowing a steady 20 mph, gusting to around 30 mph. I didn’t need a wind chill chart to tell me the effective temperature was in the 30s.

I was so focused on dealing with the cold I wasn’t paying much attention to my surroundings. Deciding to do one more hill, I rounded a corner, and the brilliantly sunlit, snow-covered San Gabriel Mountains came into full view. It was just jaw-dropping!

Here is a wider view of most of the Front Range of the San Gabriels, white with snow.

Ahmanson Ranch Out and Back Trail Run from the Victory Trailhead to the Las Virgenes Trailhead Via Lasky Mesa

Runner on “The Beast”

The direct out and back trail run from the Victory Trailhead at Ahmanson Ranch through East Las Virgenes Canyon to the Upper Las Virgenes Canyon Trailhead is about 3 miles each way.

This variation bypasses most of East Las Virgenes Canyon. It climbs up to Lasky Mesa and then descends “The Beast” to East Las Virgenes Canyon about 0.4 mile before it joins the fire road in Upper Las Virgenes Canyon. This fire road can be followed south to the Upper Las Virgenes Canyon Trailhead, the turnaround point.

Depending on the exact route, the trail run totals about 7.5 miles, with about 825 feet of cumulative elevation gain. The Beast is the longest continuous hill and is about 0.8 mile in length.

Here is an interactive, 3D terrain view of my out and back trail run from the Victory Trailhead at Ahmanson Ranch to the Las Virgenes Trailhead via Lasky Mesa. The direct route through East Las Virgenes Canyon is also shown. The map can be zoomed, tilted, rotated, and panned using the navigation control on the right. Track and placename locations are approximate and subject to errors. Poor weather and other conditions may make this route unsuitable for this activity.

When it rains a lot, sections of East Las Virgenes Canyon can get really muddy. This route avoids the worst of the gooey, stick-on-your-shoes mud.

Update January 17, 2023. With the additional rainfall this January the “best” route up to Lasky Mesa is on the dirt road. The single track is wet and muddy in spots.  The lower half of the Beast is eroded and somewhat muddy. I have a pair of shoes that I use in the muck and wet. They haven’t dried out for weeks.

The clouds were associated with a front that stalled to the north of Los Angeles, resulting in some surprising and substantial rainfall totals in Santa Barbara and San Luis Obispo Counties. No measurable rain was reported in Los Angeles County by the NWS.
