Coming up the Valley of the Thoroughfare, west of the Absaroka Mountains and south of Yellowstone Lake, the trail followed the North Fork of the Yellowstone. Crossing over Two Ocean Pass, the trail split east and west around Terrace Mountain into the Wind River Valley at DuNoir. From Union Pass south bound travelers could use the Green River Valley to connect east through South Pass or west toward the Snake River.

Q: Passage: Edwin Bergstrom studied architecture at the Massachusetts Institute of Technology and at Yale University. He began his architectural practice in New York City in 1899 and then moved to Los Angeles in 1903. He partnered with John Parkinson soon after arriving in Los Angeles. After leaving the partnership with Parkinson, Bergstrom oversaw a successful solo practice. In the 1920s and 1930s, Bergstrom was associated with the Pasadena architectural firm of Bennett and Haskell. He won a design competition in 1923 to design the City of Pasadena Civic Auditorium, which anchors the south end of the city's civic center. In the late 1920s, Bergstrom was one of five prominent Los Angeles architects, organized as the Allied Architects of Los Angeles, involved in designing the Los Angeles County/USC Medical Center General Hospital (1933), an architectural monument in East Los Angeles. Bergstrom was commissioned as the chief consulting architect for the United States War Department in 1941. In this capacity, he served as the chief architect for the Pentagon in Washington, D.C. (194143). Bergstrom was also actively involved in the American Institute of Architects (AIA), serving as the national organization's treasurer for over 40 years and as president in 1939 and 1940. During their partnership, Parkinson & Bergstrom became the dominant architectural firm hired to design major buildings in Los Angeles. This prominent partnership designed over 25 buildings in the 10 years of their collaboration, with the majority located in the city's burgeoning downtown. Besides the Metropolitan Building, there are four other Parkinson & Bergstrom buildings located within the boundaries of the Broadway Commercial and Entertainment Historic District. As is evidenced in the Metropolitan Building, Parkinson & Bergstrom commercial buildings typically reflect influences of the Beaux Arts or Classical Revival styles popular at the turn of the century with exterior use of glazed terra cotta, decorative spandrel panels, low relief sculptural ornamentation, and large projecting cornices.
