Ran into this map of the Bell Telephone system in July 1, 1909 - we had telephone service back then - so did Sumas and Blaine but none of the other towns. Maple Falls had about 2,000 residents - timber and mining.
Interesting too that the cable to connect to Victoria and Vancouver, BC had their terminus in Bellingham. Wondering if the facility is still standing?
