My Dad worked for the Bangor Daily News, I remember him reporting on the last river drive on the Machias river, in the '70's. You can still see 4' pulp wood on the bottom of a nearby lakes. I have dragged logs from rivers and sawn them, I used some in my Mill building. Cut with axes on the butts. A lot of Hemlock, Pine and Spruce.
There is a wild shot of timber flying down a steel shoot and into the air about half way through this clip.
