The right hand route climbs a long wooded hill with a deep valley on the right and occasional cliffs of schist intruded by reinforcing granite dikes on the left. The view back near the hilltop (12.5) offers, through a frame of trees, a panorama of the Mount Holyoke and Mount Tom Ranges surmounting the Connecticut Lowland. The New England upland begins at the hilltop (13.1) in Goshen. Just past Goshen Pond (13.6), a road continues straight ahead to Ashfield, and the hard surface of the Berkshire Trail curves left. Ledges of flaggy Goshen schist outcrop from Goshen to Swift River (18.4); the banding of the ledges is almost horizontal at one place (14.6) and makes excellent flagging for garden walks. The west-flowing Swift River tumbles into the deeply entrenched, east-flowing Westfield River at Swift River village, and the combined streams flow due south through a “door” in a vertical wall of Goshen schist so narrow and inconspicuous that the water appears to run downhill and then up again. The Berkshire Trail follows up the north bank of the Westfield River as far as the lower bridge (19.5), at Cummington, where a road to Chesterfield turns left (19.6). The Plainfield road branches off to the right across the river at the center of Cummington (20.5), and it climbs almost continuously from the Westfield valley to the summit of the New England upland at the Plainfield corner (24.5). Here the broad, gently rolling expanse of country offers no suggestion of the deep valley only three miles away. The tour takes the road right (Route 116) to Ashfield (33.0), Conway (40.2), and South Deerfield (46.6), where it turns south on Federal Highway 5, returning to Northampton (58.6) over ground that is covered in another tour (see pp. 87-88). The twenty-two miles of country between Plainfield and South Deerfield contain a succession of highland views, glimpses into youthfully incised valleys, and a final sweep of Connecticut lowland that defy description. Nearly everywhere the glaciers of the Ice Age have scraped away the soil and have exposed the underlying metamorphosed sediments. Their high structures and their metamorphism show that they are merely the roots of an ancient range that once rose majestically to summits which, were they restored, would dwarf the planed upland of today. Rugged as some of the topography may seem, prolonged erosion has greatly softened and tamed it. (For more details of the features which can be seen along this route, see pp. 94 -95.) Trips from Greenfield The most popular drive from Greenfield is westward over the Mohawk Trail, but the eastward continuation of this highway to Orange, combined with the Daniel Shays Highway to Pelham, offers almost equal attractions and should not be missed. _Mohawk Trail, Adams, Plainfield, and South Deerfield_
