San Gabriel Peak is a summit in the San Gabriel Mountains in the U.S. state of California. It was named by the United States Geological Survey in 1894 and is located in the Angeles National Forest. This peak was first named The Commodore for Commodore Perry Switzer. The name is derived from the Misión del Santo Arcangel San Gabriel de los Temblores. From this mission had already come the names of the San Gabriel River and San Gabriel Canyon, the mountain range itself and the entire San Gabriel Valley.

The steep south face drops approximately 1,000 feet into the center of an amphitheater at the top of Eaton Canyon, forming one of the most sustained steep slopes in the Western San Gabriel mountain range. Zenshūyo (禅宗様?, lit. Zen style) is a Japanese Buddhist architectural style derived from Chinese Song Dynasty architecture. Named after the Zen sect of Buddhism which brought it to Japan, it emerged in the late 12th or early 13th century. Together with Wayō and Daibutsuyō, it is one of the three most significant styles developed by Japanese Buddhism on the basis of Chinese models.

Kōzan-ji’s butsuden in Shimonoseki, Zenpuku-in’s shaka-dō in Kainan, Wakayama and Anraku-ji’s pagoda in Ueda, Nagano, all dating to the Kamakura period, are considered the three most important Zenshūyō buildings. Kōzan-ji’s butsuden (built in 1320) is the oldest extant building in the Zenshūyō style in Japan. At the end of the 12th century, more or less while in Nara Chōgen was rebuilding Tōdai-ji, and in the process was creating the architectural style that would later be called Daibutsuyō, two monks were introducing Zen to Japan.

A little later, Dōgen introduced the Sōtō school to Japan. Unlike Eisai, he declined the support of Kamakura’s regent Hōjō Tokiyori and open his head temple, Eihei-ji, within the forests of today’s Fukui prefecture. The success of the Zen sects, which were embraced by the warrior caste, meant that they were able to introduce to the country also a new architectural style, like the Daibutsuyō derived from Song Dynasty architecture, but very different in spirit.

After arriving in Japan the style started to evolve in response to local conditions and tastes. Among its innovations is the roof, covered in wood shingles rather than tiles, as in China. Also, Zen temple buildings have a so-called “hidden roof” structure, consisting in two roofs, the true one and a second underneath it. The second, false roof hides the first, making it possible to obtain sloping roofs and shallow eaves. The invention of the hidden roof in the 10th century allowed the inclination of the roof’s underside to be completely different from that of the exterior, thus making Japanese temples feel very different from their Chinese counterparts.
