Postcard - Shaniko, Oregon

"Shaniko, Oregon. Easily most important relic in present day Shaniko is old Shaniko Hotel, prominent red brick building, middle distance. Built in 1900 as "Columbia Southern," venerable hostelry still serves resident and traveler alike. Veterans of once savage wars between cattle and sheepmen now live peacefully together in retirement. Sightseeing travelers find delicious meals served in historic surroundings. Many wagons, buggies are shown to public in open fields, under shelter and in old warehouses."

I'm going to guess 1960s.
