In their forecast discussion for today, the NWS Los Angeles Oxnard commented, “A long-lasting and extreme heatwave will continue across the region, and especially the interior…” The high temperature was expected to range from 105 to 115 across the interior valleys, mountains and deserts.
I was doing the Trippet Ranch Loop from the Top of Reseda. The highs on the San Fernando Valley side of the Santa Monica Mountains were expected to be in the 90s. But keep in mind that’s essentially the temperature in the shade. In full sun, the temperature could be 10 to 15 degrees higher. When I reached the Hub, at 7:00 in the morning the in-the-sun temperature was already around 90 degrees.
I hadn’t run very far on the Musch Trail when I came across a remarkable spider web. The spider had ingeniously bowed a flexible stalk of tall grass to build its web. This solution avoided having to span the web between two stalks. I also wondered if the added tension would make the web more efficient.
From the camp, the Musch Trail climbs about 400′, in a bit over a mile, to the junction of Eagle Rock and Eagle Springs Fire Roads. A left turn here leads past Eagle Rock to the top of the Garapito Trail.
Other than the Bent Arrow Trail—which remains closed—the Garapito Trail is the “End of Reseda” trail most impacted by our back-to-back wet rain seasons. At times, washouts, debris flows, slides, fallen trees, and vigorously growing chaparral plants have made the trail nearly impassable. The Santa Monica Mountains Task Force worked tirelessly over the Winter to restore the trail.
Of course, the rain that caused all the problems on the Garapito Trail has also resulted in numerous wildflowers along that trail. Today, some of the most prominent were scarlet larkspur, scarlet monkeyflower, Indian pink, and Plummer’s mariposa lily. And, Garapito Creek was still trickling in July!
The eye-catching colors of apple galls are like nothing else in chaparral and impossible to miss. These are on scrub oaks along the Stunt High Trail in the Santa Monica Mountains.
The galls are chemically induced by the larva of the California gall wasp, which uses the gall for food, protection, and to pupate. The rose color appears to result from exposure of the gall to sunlight.
I was descending the Stunt High Trail after visiting Saddle Peak while doing the Topanga Ridge Loop. As in other parts of the Santa Monica Mountains in which I’ve run following Hilary’s deluge, the trails were somewhat more eroded than usual but in OK shape.
The Rivas Canyon Trail connects Will Rogers State Park to Temescal Canyon. Today (and last weekend) I ran it as part of a long loop from the “End of Reseda” at Marvin Braude Mulholland Gateway Park.
Was running down the Chamberlain segment of the Backbone Trail Saturday, when a flash of bright red on a manzanita bush caught my eye.
Very bizarre, as nature often is. At first glance I thought the bulbous red objects on the manzanita were some kind of larvae, but on closer inspection could see it was a swelling of the leaf. My first thought was some kind of viral infection.
What they turned out to be are aphid induced leaf galls. Galls generally provide a protective habitat and enhanced food source for the inducing species and their tenants.
