Heaton Flat Trail

The Heaton Flat Trail is one of the most rewarding in terms of mountain scenery in the San Gabriel Mountains. It begins at Heaton Flat, not far beyond the parking lot at the end of East Fork Road. For details of the trail itself, see Dan Simpson's or Tom Chester's web pages. This trail is part of Hike No. 87 in John Robinson's book, Trails of the Angeles. Be aware that the trail is rough in places, and less frequently used. But it is readily walked to Heaton Saddle, with an elevation gain of about 2,500 feet in approximately 4.5 miles. There are several destinations beyond that, but on rugged trails, generally not recommended.

All of the photographs here were taken in February, less than a week after a winter storm that deposited considerable snow on the mountains. Although the spring flora was limited, there was plenty to see, including a variety of ferns, and multitudinous numbers of the white-flowered Ceanothus crassifolius at the peak of their bloom, and budding sugar bush (Rhus ovata).
