Mt. Islip in the San Gabriels

Join us on Sunday, June 17, for a hike to the 8251 foot summit of Mt. Islip, where we will be rewarded

with gorgeous views of Crystal Lake, the surrounding range, and the urban habitat of more than ten million people below. Since this is one of the highest peaks in the range, many major peaks will be below us. On a clear day, we can see from the Pacific to Palm Springs; towards other major peaks; and across the high desert to the north. 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 1427' over a 2.1 mile course for a 4.2 mile round trip.

What to Bring: Weather forecasts can’t always be trusted for temperature swings, which can be unpredictable at this altitude. The snow has melted away, but it can still be cold in the upper elevations of the range. As a general rule, temperatures on the mountain average twenty degrees less than temperatures in the basin below. Dress in layers, with a jacket and sweatshirt to pull over in case it's needed. Wicking nylon shirts strongly recommended, as cotton shirts transmit cold when dampened by perspiration. Be able to strip down to a shirt just in case it becomes unseasonably warm. 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.” (navigate to 936 Milmada Dr, La Canada) We will then carpool up to the trailhead, approximately one hour up the highway, 35 miles north of La Canada, just past Mt Waterman.

Special Note: $5 Adventure passes required for all drivers. We 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’15, and Bill Sullivan, AB’90.
