The walls remained standing, and the Northern Pacific began to dismantle the structure, removing some 40,000 of the unique Roman bricks manufactured by Gladding, McBean that would be used to construct still-existing train stations in Missoula, Montana, and Wallace, Idaho.

Later additions included a circular lunchroom, an underground swimming pool, a science and industrial arts complex,[8] a gymnasium, and a multi-story parking lot structure with tennis courts on the roof.

Among those who spoke there were Theodore Roosevelt, Woodrow Wilson, Warren G. Harding, William Jennings Bryan, and Billy Sunday.

[10] The stadium was originally built in 1909–1910 using steam shovels and sluicing to move more than 180,000 cubic yards (140,000 m3) down the edges of the gulch to create a flat playing field of 2.5 acres (10,000 m2).

Wooden molds were built to cast concrete for 31 rows of stadium seating surrounding the playfield.

[11] During the renovation, students were temporarily relocated to the old site of Mount Tahoma High School in the south end, just over 7 miles (11 km) away.

[12] Stadium High School was used as a filming location for the 1999 popular teen comedy movie 10 Things I Hate About You.
