The the Military and wagon road from Walla Walla Colville was the first wagon road in Eastern Washington. It branched off from the Oregon Trail at Fort Walla Walla and headed north to Fort Colville. We have reworked historic maps of the route and put them here to show the relation of the historic route to the current landscape. We will update this as we get better information. If you have any of that information, please contact us.
