Here is an Alberta forum reference to the wolf at http://www.outdoorsmenforum.ca/showthread.php?t=34797&highlights=wolf.

One of the posters here also makes reference to another wolf killed 10 years ago near Buffalo Jump in Alberta and weighed in at 205 pounds.

I know I have seen references to 200 pound wolves from the southen Yukon but in pre-internet days and I cannot remeber where.

I sent an e-mail to the Yukon Fish and Game people asking them about this but they did not reply.
