The story that haunts this land

Your quest begins at the Whitman Mission National Historic Site, 328 Whitman Mission Rd, Walla Walla, WA 99362. It was here that Marcus and Narcissa Whitman established their Protestant mission in 1836, at the junction of the Walla Walla River and Mill Creek, aiming to convert the Cayuse people. You examine the foundations of the mission buildings, the restored millpond, and the irrigation ditch, remnants of an era of colonization and growing tensions in the Washington Territory.

Continuing your exploration of the Whitman Mission National Historic Site, you proceed to the Whitman Monument. This memorial obelisk overlooks the site from a hill, commemorating the 1847 Whitman Massacre. A short climb takes you to the summit, offering 360-degree views of the Walla Walla River Valley and the Blue Mountains, a panorama unchanged since the tragic events that claimed the lives of 13 people, including Marcus and Narcissa Whitman, on November 29, 1847.

At the base of the monument hill, you discover the 'Great Grave,' the mass grave where the 13 massacre victims rest under a marble slab. This place of remembrance recalls the fate of the survivors, about fifty people held hostage for one month and finally released on January 8, 1848, thanks to the ransom paid by the Hudson's Bay Company. The remnants of the Oregon Trail that cross the site bear witness to the pioneers' passage.

Your journey then leads you to Pioneer Park, approximately 7 miles east of the Whitman Mission in Walla Walla. This historic park is linked to the pioneer period and the Oregon Trail era, with elements that evoke colonization and mission activities. As you walk through Main Street in Walla Walla, you observe 19th-century architecture, reflecting the urban development that followed the 1847 events, which accelerated U.S. territorial expansion in the region.

The Fort Walla Walla Museum, 25 miles west of the Whitman Mission, marks the final stage of your investigation. This museum complex preserves the history of the original Hudson's Bay Company Fort Walla Walla from 1818, closely linked to the massacre events. It was here that Peter D. Hall escaped on November 30, 1847, to report the tragedy. The museum also illustrates the Hudson's Bay Company's role in ransoming the hostages, offering a comprehensive perspective on this crucial period in the history of Walla Walla and the Washington Territory.
