There are some excellent books, and DVD's on hunting mule deer. Glenn St. Charles' book Bows on the Little Delta, has several chapters on hunting Mule deer in Washington (Chapters, 3, 4, 16,17, and 28. One main difference between Mule Deer, and the others species is the Mule Deer migrate from their summer range (4000 ft or higher elevation) to lower elevations with heavy snow. The four hunters and their trophies on page 253, were taken in Nason Creek during the migration. I have hunted from the Chalet (p 32) without snow and few deer, but with snow they may be everywhere. In late winter, page 318 their may be 10 ft. of snow where the Chalet was once. The Chalet has been gone for awhile, the USFS demolished it. The deer still migrate out of the high country when snow becomes too deep. The point is Mule Deer, Whitetail, and Blacktail Deer frequently live in different habitat and learn to adapt to it and seasonal changes. Scouting is essential if your going after big Mule Deer. Whitetail will hang out in the same area year around, whereas Mule Deer travel long distances from their Summer range to Winter range.
