A lookout (29.4) affords a memorable view of the sharp V-shaped gorge of the Deerfield River cut deep into the highland surface, which stretches unbroken to the horizon, with only a few divides rising to greater elevations in the west and northeast. A set of broad rock benches, about 200 feet lower than the upland, forms a strath terrace (see pp. 46-47) which closely follows the river’s course. Great landslide scars, caused by the heavy rains accompanying the 1938 hurricane, mar the valley walls far to the north and again eastward from Zoar. The road to Zoar (30.2) turns right a short distance east of the Whitcomb Summit (30.6), where lookout towers at an elevation of 2,240 feet enhance the excellence of the view westward across other straths to Mount Greylock, the highest point in Massachusetts. From these same vantage points, one may survey the deceptively smooth slope of the New England upland eastward down the course of the Deerfield towards the Atlantic coast. [Illustration: Pl. 10. _View of the Deerfield gorge from the east summit of the Mohawk Trail._ _The high level flat to the extreme right and extreme left is the New England peneplain. The terrace bordering the steep walls of the gorge is a strath._] The road crosses a series of strath heads, which drain into the Cold River, and ascends to the west summit (33.2). At first it seems possible to throw a stone into North Adams, so abrupt is the western slope. The city lies deep in a limestone valley, and beyond it the Taconic ranges rise steeply west of Williamstown, over six miles away. On the long descent into the valley, the roadway is cut into albite-biotite schists with horizontal cleavage. Above and below the sharp hairpin turn (35.2), there is a beautiful view to the south along the strike of the limestone trench and along the route (State Highway 8) which is to be followed from North Adams (37.8) to Adams. Not far south of North Adams the road passes the west portal of the Hoosac Tunnel (39.4). Boulders on the mountainside east of the highway are glacial erratics which were left above the level of the valley trains and above the surface of glacial Lake Bascom. The limestone which outcrops on the slopes of Mount Greylock west of the road is used for lime (41.6), and the quarries provide ideal exposures for a study of the rock. The burning plant (42.2) is at the roadside. The road branches in the center of Adams (43.6), one route (State Highway 116) continuing ahead to Savoy and Plainfield, the other veering right to Mount Greylock, Dalton, and Pittsfield.
