Near Prescott in Walla Walla County, Washington — The American West (Northwest)
Halfway House
on the Mullan Road
The construction of the Mullan Road by Lt. John Mullan and his crew of 100 civilians and 100 soldiers began in Walla Walla in June of 1859, and was completed in October of 1860. In May, 1861, Lt. Mullan began rebuilding and improving portions of the route. In August 1862, the 655 mile road, including the previously existing portion from Wallula to Walla Walla, was finally completed, providing a route for pioneer families, miners, and military supplies between two of the country’s major rivers. The completion of the road realized the long-held dream of President Thomas Jefferson of linking the continent from east to west.
In 1866 a memorial to the U.S. Congress by the Montana territorial legislature in Helena pleaded for repairs, and reminded Congress of “the necessity for a great national highway connecting the Missouri and Columbia rivers by a good and substantial wagon road.” Though the figures used were perhaps an exaggeration, the memorial went on to say, “From Jan. 1 to Nov. 15, 1866, 1500 head of horses have been purchased by individual miners at Walla Walla; 5000 head of cattle were driven from Walla Walla to Montana; 6000 mules have left the Columbia river and Walla Walla loaded with freight for Montana; 52 light wagons with families have left Walla Walla for Montana; 31 wagons with immigrants have come through from the States via the Mullan Road, a portion of whom settled in Walla Walla valley... not less than 20,000 persons have passed over the Mullan road to and from Montana during the past season; $1,000,000 in treasure has passed down through Walla Walla and Wallula during the same period.”
Ben Flathers operated a pack train along the California coast from 1854-61 before moving his operation to The Dalles, from which he packed to the Montana mines through Walla Walla. There he met Malinda Harris, whose husband and sons had died. In 1869 they were married, and acquired land along the Touchet River from Henry Hart Spaulding, son of Rev. Henry Spaulding, missionary to the Nez Perce Indians.
Here they established their Halfway House just south of the present intersection of Highway 124 and 125, and west of where the town of Prescott was established in 1882 as a railroad station on the Oregon Rail & Navigation Company (OR&N) line.
