From this evening's run at Ahmanson Ranch.

Did the Will Rogers - Temescal Loop this morning from the End of Reseda. It had been more than a month since we'd had measureable rain in Los Angeles and it was great to be out in the Santa Monica Mountains after a rainstorm, dodging a few mud puddles and enjoying the good running weather!

A key segment of the 21 mile loop is the Rivas Canyon Trail, which connects Will Rogers State Historic Park to Temescal Gateway Park. Each time I run the trail I'm blown away by the oceans of Cape ivy in Rivas Canyon. Having grown up in the Southeastern U.S. it reminds me of kudzu.

Both are introduced perennial climbing vines -- kudzu from Japan and Cape ivy from South Africa. Both are prolific and can cause severe negative impacts to native plants and other vegetation.

More information about Cape ivy (Delairea odorata) can be obtained on the California Invasive Plant Council web site.

From today's run at Ahmanson Ranch.

These valley oaks have dropped their leaves, but if you were to go by the warm temperatures we've been having in Southern California, you might think it was Summer.

Including today, the high temperature at Pierce College in Woodland Hills, California has reached into the 80s each of the last six days. High temperature records for December 31 - January 5 have been broken at several locations. Among the records broken, yesterday San Gabriel recorded a high of 91, Camarillo 90, and UCLA 89.

It sounds sweltering, and it can be if you're in full sun, but it's not like a 90 degree day in July. Days are short, shadows long, and some north-facing slopes never see the sun. And it does cool down quickly. If you take a look at the overnight lows on those six 80+ days at Pierce College, you'll see the temperature dropped to around 40-42 degrees.

On my run Tuesday afternoon, when the photograph of the valley oaks was taken, the temperature varied by as much as 20-25 degrees between some high and low points.

It has been great weather for running, but I'm ready for a change in the pattern and a little rain!

The view above is of crags in the Circle X area and the Channel Islands from the Etz Meloy section of the Backbone Trail in the Santa Monica Mountains.

From today's out and back run on the Backbone Trail from Kanan Road to a viewpoint on Etz Meloy Mtwy fire road. The fire road continues west about a mile and links to the Yerba Buena segment of the Backbone Trail.

The segment between Kanan Road and Yerba Buena Road includes the two remaining gaps in the Backbone Trail -- the 0.1 mile Etz Meloy gap and the 0.4 mile Upper Trancas gap.

Here are a few additional photographs from the run:

From a late afternoon run on December 8. The moon is about 98% full, and about a day and a half away from the total lunar eclipse that occurred before sunrise on December 10, 2011.

There are about 15 creek crossings on the Serrano Canyon Trail. In a wet rainy season you might even get your shoes wet!

From last Sunday's adventure run over Boney Mountain and down to Serrano Valley.

Craig had never done any rock climbing, but was doing a great job of scrambling up the steep gullies, and climbing the short sections of knobby, low angle volcanic rock. We were climbing up through a maze of brush and rock formations on the steep ridge that follows Boney Mountain's western escarpment. The scramble up the western ridge would be well worth the effort. The route is a shortcut to the Backbone Trail and some of the most spectacular running in the Santa Monica Mountains.

Our run had started at Wendy Drive & Potrero Road in Newbury Park. We were doing a 20 mile loop that was about as varied as a trail run can be. In addition to the 1.5 mile ascent of Boney Mountain, there would be about 13 miles of single track trail, 4.3 miles of dirt road, and even 1.7 miles of paved road.

After getting through the maze to the Backbone Trail we would do the classic run down the Chamberlain Trail to the Old Boney Trail. From the bottom of the Chamberlain Trail there are four major variations. Three of these lead to Big Sycamore Canyon and one loops directly back to the start of the climb up Boney Mountain:

- Turn left (west) on the Old Boney Trail and at the junction of the Serrano Valley & Old Boney trails follow the Serrano Valley Trail and then the Serrano Canyon Trail to Big Sycamore Canyon. This was the route we were doing today.

- Turn left (west) on the Old Boney Trail and follow it all the way to Big Sycamore Canyon.

- Turn right (east) on the Old Boney Trail and at the junction of the Blue Canyon & Old Boney trails, continue down the Blue Canyon Trail to the Danielson Multi-use area in Big Sycamore Canyon.

- Turn right (east) on the Old Boney Trail and at the junction of the Blue Canyon & Old Boney trails, turn up the Old Boney trail and  follow it  over the shoulder of Boney Mountain and back to the point where the ascent of Boney Mountain began.

In Big Sycamore Canyon there are many options. Today we would run up Sycamore Canyon Rd to Wood Canyon Rd and pick up the Two Foxes Trail. This trail continues up-canyon and eventually rejoins Sycamore Canyon Rd, which would take us to the Upper Sycamore Trail, and from there to Danielson Road and Satwiwa. Here's an interactive Google Earth browser view of a GPS trace of our route. This PDF map from LAMountains.com shows many of the trails in the area.

Note: There is an easier alternative to the western ridge route on the north side of Boney Mountain. The route starts near the Danielson Memorial, and ascends a use trail up the eastern ridge on the north side of the mountain. In places the (unmaintained) trail is very steep, eroded, and rubbly but it is more straightforward and less technical than the western ridge.

Don't know where it's going,
but that's part of the deal.
Get to the top, look around.
Take a deep breath,
and run back down!

From this evening's twilight run through El Escorpión Park.

This morning did the Boney Mountain north side loop with Tom and Elisa, who were visiting from Idaho.

Thanks to a moderate offshore flow, visibility from the high point at the top of the ridge (2900'+) was spectacular.

Anacapa and Santa Cruz Island loomed nearby, their eastern shores only 25 to 30 miles away. To the left of Exchange Peak and about 50 miles distant, the low silhouette of Catalina seemed to hover above the shimmering ocean. A little more to the east and about 40 miles away, Palos Verdes Peninsula jutted from behind Sandstone Peak and into the Pacific.

To the north and northeast Hines Peak (27 miles) and Cobblestone Mountain (33 miles) were prominent. A little further to the east and across I-5 Liebre Mountain and Burnt Peak (44 miles) could be seen.

Many of the peaks of the San Gabriel Mountains were easily seen, including Mt. Baldy about 75 miles to the east.

The distance winner was Mt. San Jacinto, a hard to see smudge in the haze on the eastern horizon, about 130 miles away.
