The trail passes through the “Horse Sheds” to the south base of the Range, following the contact of the lava with the overlying sandstone for about one-half mile on the way towards Hilliard Knob. This eminence lies over half a mile north of the crest of the Range, for it has been offset by faulting, much like the displacements near Mount Norwottock and Notch Mountain, and the trail passes suddenly from the conglomerate above the lava flow to the conglomerate below it. Trail markers must be observed closely through this section because many wood roads cross the path. Eastward the way again leads upward to the lava and follows the crest of a low section of the Range, but soon another fault breaks the continuity of the ridge, and the high top of Flat Mountain stands out on the far side of a deep hollow. The hollow is underlain by sandstone below the lava sheet, and the trail follows down the steep dip slope of the beds, only to ascend again towards the reddish basalt cliffs of the mountain. At the base of the flow, the bed of a dry brook exposes a mass of frothy lava. The best views from the top of Flat Mountain are those along the south slope of the Range towards Mount Tom, and northward across the Hadley lowland. The path then turns down the north face of the mountain some 200 yards along the crest from the west end and, passing over a series of conglomerate ledges underlying the lava, it continues along a wood road beside a steep-sided brook until it comes to the Bay Road at the fork to Dwight and Belchertown. Any nature lover will find the trail very interesting. The views from the western half are unexcelled. Wild flowers and birds abound along the less frequented eastern section. Anyone wishing to see how molten lavas and earth movements in the distant past have influenced the topography of the present will find the far eastern walk a veritable revelation.
