The road from Westfield and the airport (Federal Highway 202) from the left, and the road to Easthampton (7.6) turns left from the main highway, which continues north. The north route, described under the tours from Northampton (see pp. 80-82), features the dinosaur tracks and the succession of Triassic rocks. The Easthampton road goes past the south end of the Mount Tom Range, and its scenic attractions have been dealt with elsewhere (see p. 85). Its most interesting sights are the line of lakes between the two volcanic series and the view from the summit of the ridge. Easthampton (12.7) lies on the old lake bottom, from which an impressive view of the palisade of massive columns comprising the tilted lava flow of Mount Tom can be obtained. At Easthampton the tour turns south on the College Highway (State 10) towards Southampton and Westfield. The road follows the gravel plain which was spread into Lake Hadley by streams flowing out of the western highland. The plain is dissected locally by the Manhan River (15.2 and 18.0) which crosses the road twice, and one small valley near Southampton (17.1) discloses Triassic arkose buried by the sand. The road rises above the lake deposits (17.4) near the Manhan River, and at once glacial erratics become numerous. The “land of stone fences” forms a narrow divide between the Lake Hadley basin and the Lake Springfield sand plain (21.1), which extends south to the valley of the Westfield River. The Holyoke road (22.5), which enters from the left, came over the trap ridge and across the lake plain. As the College Highway approaches the edge of the Westfield valley (23.6), it slopes steeply down to the level floor cut by the river. It crosses the Westfield (24.5) and comes to the junction (24.9) with the Jacob’s Ladder route (Federal Highway 20), which offers another interesting sidetrip into the Western Upland. The route continues south to the center of Westfield (25.2), leaving the College Highway at the south end of the common. The Springfield road goes around the central square and starts east in the valley which the meandering Westfield River carved out of the Lake Springfield sediments. The terrace levels and the scalloped pattern of the meander scarps are conspicuous along the lowland. The highway crosses the Little Westfield River (26.1) and then the Westfield itself (27.0) just beyond the entrance to Robinson State Park.
