While on our SE Alaska cruise this spring we stopped at Port Alexander again, which is a tiny community on the inside tip of Baranof Island. This year one of the Lodge owners had brought in a portable saw mill & was using drift wood logs to make cedar shakes. Around the town we noticed a lot of the cedar being used. This particular lodge owner was not the only one going after the more premium logs around the area. From talking with the locals, drift word was the primary source of fire wood along with a source for structure building. Salt in the logs was only mentioned in that the large diameter, but very short & old logs, was still good due to it. I don't know how the fire wood was burned for heat, but there was no mention of any problems in burning it, but there might be with the subject just not coming up. I thought it all interesting at the time & next time there, I'm going to ask if they only burn it in there homes for heat in fire places. Overall oil seemed to be the primary home heating fuel with the drift wood a secondary source.
