The First Military Road built in the State of Washington, marked by a large cobblestone pyramid erected by the Washington State Historical Society. This road was built from Steilacoom to Walla Walla across Naches Pass by the “people of the northern Oregon,” after they had become exasperated by the slow progress made by the Federal Government. The first wagon train to cross the northern Cascades traveled on this road, which was completed in 1855.
