Early morning sunlight filters through the oaks and sycamores in upper Las Virgenes Canyon.

Trying to catch its tail.
Up a trail, down a trail,
Before it scurries away.

Got caught in some showers this afternoon on Rocky Peak, returning from a rambling trail run from the San Fernando Valley over into Simi Valley.

This was one of those "not sure where I'm going" runs that unfolded as it progressed. It started near Chatsworth Reservoir at Chatsworth Oaks Park, worked over to Santa Susana State Historic Park, then up the Old Stagecoach Road. At the top of the old Stagecoach Road, I picked up the Upper Stagecoach Trail and followed that to Santa Susana Pass and the 118 Frwy. From there it was a short distance down the west side of Santa Susana Pass Rd. to the Lower Stagecoach Trail, which took me to Corriganville.

Once down in Simi Valley there are four trails that ascend to Rocky Peak road, and my return route. From the shortest to the longest, they are the Wildlife Corridor trail, Hummingbird Trail, Chumash Trail and the Marrland/Las Llajas trail. Not sure how long it would take to get back to the SFV, I finally decided on the Chumash Trail.

Running up the Chumash Trail, the wind picked up, the clouds began to lower and thicken, and the temperature dropped. Minutes after turning right onto Rocky Peak road the showers began, and it wasn't long before the sleeves came out of the pack.

The return trip, with a net elevation loss, went a little quicker than expected. Next time I'll have to give the Las Llajas option a try. That would extend the run from about 17 miles, to something over 20. The approximate elevation gain/loss on the 17 mile version was a little under 3000 ft.

If you live in the Los Angeles area and do your weekday trail runs in the afternoon, you have reason to cheer -- today the sun will set a little later. You can run (slightly) longer before you start to stumble on those unseen rocks.

According to the Astronomical Applications Dept. of the U. S. Naval Observatory, yesterday in Los Angeles the sun set at 4:44 p.m., and today it will set at 4:45 p.m.

The more northerly your latitude, the later the date before the afternoon begins to lengthen. This year, in Miami it was back on December 4, and in Seattle it will be on December 17. In Anchorage it won't be until December 19. Barrow, Alaska won't see a sunset (or sunrise) until January 23!

Gradually at first, afternoons continue to lengthen until July 5, when once again the amount of afternoon daylight slowly begins to shorten.

Part of the appeal of climbing at Joshua Tree National Park is its vastness.

There are many excellent, and often busy, roadside climbs, but there are also remote areas such as The Galapagos and Queen Mountain that see far less activity. If you like to explore, and can get by without route topos and beta, these and other secluded areas of the Park offer a wilderness climbing experience of the highest grade.

The adventure isn't just in the climbing. On a Winter-shortened day it can be a real challenge just to get into an area, much less locate a particular route on a particular formation. Even if you're more or less in the right place, a targeted route might be difficult to find -- perhaps hidden in a corridor, or on a nearby group of rocks.

And there can be many distractions along the way. It's not unusual to stumble onto a "not in the guidebook" route -- maybe a stellar face or super-clean finger or hand crack -- that has to be climbed. Of unknown origin and difficulty, such routes are untarnished by preconceptions, and have been among the most rewarding I've done.

Inevitably, the shadows will be growing long and the temps cool, as you debate whether to try and get in another climb. There is still the minor matter of getting back to the car.

Trail runners, do you suffer the embarrassment of continually being passed on hills? Legs aren't what they used to be? You need the new Hill Climbing Helper®.

The Hill Climbing Helper's portability is the key! The Hill Climbing Helper® may look heavy, and it is, but that's part of the genius of its design.

• Can be used on all your favorite trail runs!
• Fits most hills!
• More effective than elliptical or stair-climbing machines!

Some outstanding evening runs this week. Did a FiveFingers run out at Ahmanson on Tuesday, and as sometimes happens this time of year, didn't make it back before dark. Was up on Lasky Mesa in the fading light, with endorphins at full flow. In a distant grove oaks I could hear a Great Horned Owl, and with each hoot-whoo it seemed the zeal of the day was turning to the tranquility of the night. The running was effortless and ethereal.

This evening's run was also superb. Over the course of the run, the skies had become increasingly gray and troubled, as a weak cold front approached the area. Climbing a long hill, the light was dank, and I had given up on the sun. But as I neared the crest of the hill, orange-red sunlight began to illuminate the clouds from below, highlighting a sunset shower. Large, cold rain drops began to patter around me, and I watched mesmerized, as the light, clouds, and rain played on the sky.

Like flies on the sky, contrails are visually annoying, but do they also affect climate? For a discussion of the possible effects of these artificial clouds, see NOVA's Dimming the Sun: The Contrail Effect by Peter Tyson.
