The Book of SOYP Photograph Collection, between 1921 and 1936?

In 1919, David Whitcomb, president of Rainier National Park Company, and Tom Martin, general manager, came up with the idea to cache supplies at Paradise Inn on Mt. Rainier before the road was blocked with snow and to return after the new year with a group of friends who loved the outdoors. Calling themselves the Tribe of SOYP (Socks Outside Your Pants), the group first had an outing in February, 1920, and met annually thereafter. Group members skied and hiked around Paradise Valley on Mount Rainier. Each man took a Native American tribal name for his own for the duration of the weekend adventures. The first members were honored with the distinction of Tyee, as they called elders, while newcomers were given lesser distinctions until they proved they were worthy of membership in the tribe. The group would travel as close as possible to the mountain by coach or train, and then hike to a lodge at Paradise that had been stocked with provisions the summer before. Notable members on the SOYP attendance chart include photographer Asahel Curtis and lumberman Philip Weyerhaeuser.
