The wolf is apparently for real and weighed 197 pounds. The refernce to 230 pounds is what it would have weighed if it had a stomach full of moose. It had an empty stomach. The skull scored 18+ inches or about what a 200 pound leopard of jaguar would score.

There are more details on the huntingbc forum and comments by a guy who saw the wolf and who also saw it weighed. There is also a guy on the site who mentions 200 pound wolves from the Yukon.

This all fits in with information that I have accumulated over the years that tends to show the largest wolves on earth live within the range of the wood buffalo. They are in the Mackenzie Valley NWT, northern Alberta, northern Saskatchewan and the southern Yukon.

They are the only wolves that seem to kill adult bison and size probably has something to do with it.
