The Blackman House is the only home to have survived of the three built on Avenue B by the Blackman brothers from Maine. The Blackman Bros. Co. grew to dominate the early lumber industry of the Snohomish River Valley. Just two doors up from First Street (118 Avenue B), the historic home offers two floors of period furnishing where you can sit with a cup of tea and listen to the stories of early Snohomish.
