The Deerfield River is a major tributary of the Connecticut River.  The mainstem of the Deerfield is more than 70 miles long, starting in the southern central Green Mountains of Vermont and flowing through portions of the northeastern Berkshire Mountains of Massachusetts.  This guide shows the major points of interest in the watershed, including conservation land, boat ramps, picnic areas, campgrounds, swimming areas, as well as access points for hiking, skiing, biking and equestrian activities.  It was prepared by the Appalachian Mountain Club in 2007.  Free.
