Advanced Day Hike: Mt. Williamson via the Pacific Crest Trail in the San Gabriels


Join us on Sunday, August 5, for a hike to the 8500 foot summit of Mt. Williamson. While our previous peaks this season have offered south facing views across the urban basin, this summit will reward us with views of the high desert and San Andreas Fault to the north. Devil’s Punchbowl, a major escarpment of the fault, can be seen in stark detail below. Since this is one of the highest peaks in the range, many major peaks will be below us. High within the alpine zone, we’ll be treated to forests of various pines that channel the wind with a gentle roar, and vertical tapestries of meadow as snow melt causes plants and wild flowers to sprout. We’ll enjoy a victory picnic on the summit as we take in views normally seen from an airplane.

Difficulty: High. Participants must be experienced hikers in top physical condition. Not for beginners. We will climb 1700' over a 2.5 mile course for a 5 mile round trip.

What to Bring: We hike the upper elevations in summer to beat the heat. As a general rule, temperatures on the mountain average twenty degrees less than temperatures in the basin below. We are starting early to get off the mountain before the summer thunderstorms, which usually form at around 4 pm. Wicking nylon shirts strongly recommended, as cotton shirts transmit cold when dampened by perspiration. Hat, sunscreen, sun glasses, boots, picnic lunch and two quarts of water required. Optional snack to share.

Where to meet: at the La Canada ride share point, just two blocks north of where the Angeles Crest Highway climbs from the 210 towards the mountains. From the 210 freeway, exit at Highway 2, the Angeles Crest or “Highway to the Stars” and drive uphill towards the mountains. There is an island on the east side of the road where we can park. For navigation, use “Milmada Dr. and Flanders Rd., La Canada Flintridge.” We will then carpool up to the trailhead, approximately one hour up the highway, 35 miles north of La Canada.

A $5 Adventure pass is required for all drivers. You can stop at the Clear Creek Ranger Station near that trail head to obtain them, or you may obtain one in advance at your local sporting goods store, or at the Union 76 gas station just below the 210 exit on to the 2 in La Canada. 

Leaders: Shao-Yi Qian (AB’ 2015 econ); Shannon Towey (AB 2015); Bill Sullivan (AB ’90).
