The Steptoe Battlefield Site, located near Rosalia in Whitman County, Washington, is historically significant for its association with the Battle of Tohotonimme (also known as the Battle of Pine Creek or the Steptoe Disaster) on May 17, 1858. This engagement was a pivotal clash between a command of approximately 164 U.S. Army soldiers, led by Brevet Lieutenant Colonel Edward J. Steptoe, and an allied force of an estimated 600 to 1,000 Spokan, Palouse, Coeur d'Alene, and Yakima warriors. Tensions had reached a boiling point over the encroachment of American miners and settlers onto Native lands. After a running battle across the Palouse hills, Steptoe's heavily outnumbered and poorly equipped troops made a desperate defensive stand on a hill overlooking Pine Creek. Facing annihilation and running critically low on ammunition, the surviving soldiers executed a daring, silent retreat under the cover of darkness, successfully slipping through the tribal lines to Fort Walla Walla, though they were forced to leave behind their heavy howitzers and the bodies of several fallen comrades.

The shocking defeat of U.S. forces at the battlefield served as a major turning point in the Indian Wars of the Pacific Northwest, directly triggering a swift and severe military response. The federal government launched a punitive expedition led by Colonel George Wright later that summer, which ruthlessly crushed tribal resistance at the battles of Four Lakes and Spokane Plains, ultimately paving the way for the forced relocation of regional tribes to reservations and opening the Inland Empire to rapid American settlement. Added to the National Register of Historic Places in 1976, the site is preserved today as a four-acre state park heritage site featuring a 26-foot granite monument erected in 1914, honoring the fallen soldiers and marking a landscape central to the struggle for territorial control of the Columbia Plateau.

Albert W. Thompson Hall, originally constructed between 1894 and 1895 as the Administration Building, stands as the oldest surviving structure on the Washington State University campus in Pullman. Designed by the prominent Spokane architect Julius Zittel, the building is a striking and rare regional example of Chateauesque architecture blended with Richardsonian Romanesque elements. Its dramatic exterior features a rugged native basalt foundation, pressed red brick walls, and contrasting sandstone trim, all capped by a steeply pitched slate roof. Characterized by its soaring towers, conical-roofed turrets, and elaborate dormers, the building's picturesque, castle-like silhouette has served as an iconic visual anchor for the campus and the surrounding Palouse landscape for over a century.

Historically, Thompson Hall is deeply significant as the symbolic and functional heart of the university's early development as a pioneer land-grant institution, originally known as the Agricultural College and School of Science of the State of Washington. In its early decades, the building centralize campus operations by housing the president's office, the campus library, assembly halls, and various classrooms. In 1968, the building was renamed to honor Albert W. Thompson, a beloved long-time professor of foreign languages and dean of the College of Sciences and Arts. Thompson Hall's preservation and listing on the National Register of Historic Places celebrate its architectural virtuosity and its enduring legacy as the cradle of higher education in eastern Washington.
