Los Angeles sometimes gets rain in September, but usually it is the result of tropical moisture from a dissipating hurricane, or perhaps the passage of the tail end of a weakening front. It is rare to see a low as cold, deep and energetic as the upper level low that deluged many areas of Los Angeles county Friday afternoon into Saturday.

Thunderstorms raked the San Fernando Valley Friday night, and several locations in and around the Valley recorded more than an inch of rain over the course of the storm. Los Angeles set a new rainfall record on Saturday, recording 0.40 inch of rain, and rainfall records were broken across the area.

In Southern California the first rain of the season often doesn't occur until October or November and is always savored. Especially this year, when Los Angeles has recorded only 3.21 inches of rain in the last 15 or 16 months, and a developing La Nina threatens to put the kibosh on Winter rain.

I celebrated the rain by doing an out and back run to "Fossil Point" on Rocky Peak fire road. Based on the size of the mud puddles on the dirt road, this unseasonable storm appeared to be wetter than any in last year's record dry rain season. Here's a panorama of the view northwest from the fire road to Oak Ridge, the Santa Susana Mountains and beyond.

Cirque Peak from Cottonwood Lakes Basin

The sky was brightening in the east, and sunrise was approaching when I met Miklos and Krisztina at the Denny's in Sylmar. We were already wasting light. The plan was to drive from near sea level up to Horseshoe Meadows, at about 10,000' on the Sierra east side. The hike/run we had in mind was a keyhole loop from the Cottonwood Lakes Trailhead up (old) Army Pass and then down New Army Pass. If we felt OK at the top of Army Pass, we would also do Mt. Langley (14,026').

This is the large incense-cedar (Calocedrus decurrens) mentioned in the post Snowless San Gabriels. It is located on a northeast facing slope near Little Jimmy Spring at an elevation of about 7460' in the San Gabriel Mountains of Southern California. A vertical panorama better shows the size of this tree.

The scar from the 2002 Curve Fire can be seen on the left side of the tree. The black and white cap is about 7 inches wide and suggests a diameter of perhaps 70-80 inches. According to the species information in the FEIS database, in Southern California the largest incense-cedars generally have a diameter at breast height (d.b.h.) of 36-48 inches, but in the Sierra Nevada frequently reach diameters of 84 inches. According to the database, trees over about 200 years old are subject to dry rot, but large trees are often over 500 years old.

Part of the Panorama from Olancha Peak

Olancha Peak (12,123 ft.) is the prominent, pyramidal peak seen on the Sierra crest from Hwy 395, south of Olancha. Its rocky summit is above tree line, and in some years snow can persist in the east-facing summit gullies and other sun-protected areas into late June, or early July.
