Had a friend that hunted that country and those big deer in the Skykomish country were considered to be mule deer by B&C. The line that they used to separate the two is well west of the crest of the Cascade.

The north/south line between Range 10 and 11 crosses highway 2 about 1 miles east of Baring. Up the north Fork valley the river upstream of the mouth of Salmon Creek is east of the line. In the upper South Fork basin all the Beckler, Foss, Miller, etc are all east of the line. Any buck taken in that area would be considered to be mule deer.
