Instead, it was the Alaska-Yukon-Pacific Exposition that defined much of the campus's future layout. The exposition plan, also designed by John C. Olmsted, defined the University's major axis on the lower campus. Oriented to the southeast, it follows the East Asian concept of shakkei or borrowed scenery, providing the University with its primary vista of Mount Rainier on clear days. Most of the University's science and engineering buildings line this axis.
