Trippet Ranch Loop, Musch and Garapito Trails – February 2024

It’s uncommon to have back-to-back Rain Years with 20+ inches of rain in Los Angeles. During Rain Year 2022-2023, Downtown Los Angeles (USC) recorded 28.4 inches of rain — about two times normal. This rain year Los Angeles has already had about 21 inches of rain, so another big year is in progress.

Curious to see how the trail conditions compare to last year, on February 17th and 25th I ran the Trippet Ranch Loop in Topanga State Park.

The big surprise was that the fire roads on the loop — Fire Road #30, Eagle Springs Fire Road, and a short section of Eagle Rock Fire Road — generally fared better than last year. Fire Road #30 had some damage along it’s shoulder, but I did not see the numerous mudslides along these roads like last year.

The news on the trails was divided. One of the more unusual events occurred where the Garapito Trail crosses the east fork of Garapito Creek. A mudslide from a gully on the northwest side of the creek crossed the creek, and left a pile of debris on the trail. The stream may have been dammed by mud and debris for a short time. Farther up the trail, about a half-mile from Eagle Rock Fire Road, a section of the trail collapsed in a slide.

The Musch Trail was very muddy and wet in the usual places. There were a couple of slides along the trail, but all things considered, the trail was in OK shape. The Bent Arrow Trail remains closed as a result of previous storm damage.

Last year, the bloom of bigpod Ceanothus was well underway in early January. This year the bloom began about a month later but is now happening in a big way. Greenbark Ceanothus is also starting to bloom. Some peonies were blooming on an east-facing slope of the Garapito Trail, and a Fuchsia-flowered gooseberry was in bloom near Fire Road #30.

Here are some photos taken on these two runs.

Wettest 14 Months in Los Angeles in 134 Years

With over 45 inches of rain reported, the 14 months (424 days) ending February 22, 2024, have been the wettest in Downtown Los Angeles in 134 years.

To put this in perspective, this is more than three times the amount Los Angeles would see in a “normal” year.

The wettest 14 months on record for Los Angeles occurred during late December 1888 to early February 1890, when about 47 inches of rain was recorded.

After January 2023’s torrential rains and Hurricane/Tropical Storm Hilary’s drenching in August, here we are again, experiencing record rainfall.

Over the first six days of February 2024, Downtown Los Angeles recorded 10.2 inches of rain. That’s almost three-quarters of L.A.’s normal ANNUAL rainfall in just a few days and the wettest start to February on record! Some stations in the Santa Monica and San Gabriel Mountains recorded even more — over 13 inches in some locations!

How much did it rain at Ahmanson Ranch (Upper Las Virgenes Canyon Open Space Preserve)? Unfortunately the Remote Automated Weather Station (RAWS) on a hill between Upper Las Virgenes Canyon and Cheeseboro Canyon hasn’t been accurately measuring precipitation. A citizen weather station (KCAWOODL130) near the Victory Trailhead at Ahmanson Ranch recorded over 11 inches from February 1 – 6. Another station near Cheeseboro Road in Agoura (KCAAGOUR41) recorded over 9 inches.

Whatever the amount, it was a lot. Here is a short video, from a run at Ahmanson Ranch on February 7, 2024, to check out the conditions and creeks.

As I write this, more wet weather is forecast to affect the Los Angeles area, beginning sometime over the weekend of February 17-18. We’ll see!

Update Friday, February 16, 2024.  Latest forecast for Los Angeles area suggest the rain may hold off until Sunday night or Monday.
