Inside the Surgeon’s Quarters, period rooms, photographs, and objects trace pioneer life, frontier medicine, and The Dalles’ role as a Columbia River hub. Give yourself time for the vehicle buildings: the collection has more than 30 wheeled vehicles, including a stagecoach, covered wagon, horse-drawn hearses, surreys, and early automobiles. One surrey belonged to Oregon governor Zenas Moody. This is a good stop if you like historic interiors and objects; if museums are not your thing, the main house alone may feel slow.
