Hmmm, Stack talked to a PSE guy and they said that they think the insulators failed and with the high voltage running through it just caught the pole on fire. Not sure why witnesses thought there was a transformer involved.
Not sure exactly which pole it was, as I didn't go down there...I know they were talking about using snowmobiles to get back to the area, and were concerned about whether the lines were energized initially. If the trail is open today (???) maybe someone will go take a look.
The folks who were calling it in were saying it was around MP 58 "just past Hyak"
