Trips from Northampton

Northampton makes an excellent base for many drives that will gratify

the lover of scenery, of rocks, or of minerals. The drives range from

ten to one hundred miles in length, and any one of them may be extended

or shortened at the whim of the driver. To the east the hard surface of

Route 9 leads through Amherst, Pelham, and Belchertown; and to the west,

as the Berkshire Trail, it rises to the western upland via Williamsburg

and Goshen. Side roads go to Ashfield and Conway, and permit a return by

way of South Deerfield; or, via Cummington and West Chesterfield, one

may come back by way of Huntington and Westhampton. Federal Highway 5

follows the Valley north to Greenfield, whence optional return routes

are available through Shelburne Falls, Conway and South Deerfield in the

western upland; or through Orange, Pelham and Amherst in the eastern

upland. Each of these routes offers arresting views of the broad

Connecticut Valley, the picturesque gorges along its margins, and the

even-crested highlands with distant peaks of greater elevation. Indeed,

the choice of attractive drives is bewildering, even for those who are

hesitant about wandering off the surfaced highways.

In the following pages only a few of the possibilities which are

available to the motorist are described. And for each one chosen, the

striking views and the significant geological features are indicated, in

the hope and belief that the traveler may turn explorer and, in

following other byways, may reconstruct for himself many additional

details of the region's geologic past.

_Northampton, Amherst, Pelham_

The route leaves from the Court House corner on Highway 5 and the

excursion follows Route 9 eastward across the Coolidge Memorial Bridge

(1.3),[1] where a panorama of the floodplain with its many channel scars

and terrace levels is spread out below (see pp. 1-3). Beyond Hadley

(3.0) the road tops the highest river floodplain at a conspicuous

terrace (4.9) and rolls gently over the ancient bed of Lake Hadley. The

shore line of this glacial lake appears as a broad flat between Orchard

Street and Lincoln Avenue in Amherst (6-9). (See pp. 5-7.)

The route turns left at the traffic intersection (7.2) and continues to

the north end of the common (7.4), where it turns right on the Pelham

road. This road crosses the lake bottom from the Central Vermont

Railroad tracks (7.9) to the Orient (9.9), where the delta of glacial

Orient Brook made a conspicuous gravel terrace at the farthest limit of

the lake. Stone fences make their appearance (see pp. 8-9); rocky ledges

and erratics abound at higher elevations, but perched shore lines of

ice-margin lakes occur at many levels up Pelham Hill. The road to Mount

Lincoln (see pp. 51-52) turns right (11.2) just west of the Amherst

reservoir (11.4). As the road approaches the hilltop (12.9), an opening

westward through the trees reveals an unusual view of the Holyoke Range;

and the broad lowland valley from Mount Tom in the south to Mount

Sugarloaf in the north spreads out below. On the hilltop (13.3) the road

enters the Daniel Shays Highway (13.9). Mount Wachusett (see p. 15) lies

straight ahead and projects above the great expanse of the New England

upland (see p. 46); Mount Monadnock rises even higher in the northeast,

and everywhere, deep valleys furrow the highland and break its otherwise

monotonous surface.

The Daniel Shays Highway runs north to Athol, where it joins the Mohawk

Trail; but on this trip we shall turn to the right, or south, at Pelham

and follow Federal Highway 202 along the valleys in the Quabbin

reservoir watershed. Pelham gneiss is the most abundant rock along the

highway, outcropping west of the road (14.1) in a series of

eastward-dipping layers that resemble sandstone. Mount Lincoln's fire

tower stands high above the skyline directly west from the power line

crossing (16.1). The country has a gently rolling form, which was

imposed upon it by the ice sheet (see p. 9), and the miles of stone

fences represent glacial debris piled up by the early settlers in an

effort to bring agricultural order out of geological chaos. Blossoms on

the wild cherry trees along these fences and the flowering dogwood make

this a particularly attractive drive in the spring. A ledge of gneiss

with large eye-shaped crystals of reddish feldspar lies east of the

highway at 16.3 miles. As the road begins to descend (18.1), a panorama

of the broad lowland between Belchertown and Palmer spreads out below.

View succeeds view as the road drops to lower levels: At one place it is

Holyoke and Springfield; at another it is Belchertown; and finally the

highway comes to the corners (21.1) where routes lead right to Amherst,

left to Worcester, and straight ahead through Belchertown to Palmer,

Springfield and Holyoke.

The Granby-Holyoke road (Federal Highway 202) turns right at the south

end of the Belchertown common (22.0). After crossing the railroad

(22.4), it passes out upon the plain of glacial Lake Springfield (25.3)

where the stone fences cease to line the roads, because the lake

deposits cover the glacial boulders. Rocky islands in glacial Lake

Springfield surmount the flat lacustrine plain (26.9). Granby is

situated on a long rolling point (28 to 31.6) that is underlain

principally by flat-lying arkosic conglomerate, but more ancient

crystalline rocks appear just a little farther east. In this section the

lake plain is very narrow, and the drop to the Connecticut River Valley

begins at 32.3 miles and continues to the junction with the South Hadley

road (33.2), where varved clay (see pp. 4-7) makes its appearance in the

pits to the right of the highway.

The itinerary of this excursion continues on Federal Highway 202 through

Holyoke in preference to the alternate routes through South Hadley and

thence either by way of Hockanum (p. 85) or via Amherst (pp. 83-84) to

Northampton. The Holyoke road crosses the Connecticut River (33.8 to

34.1) where the Longmeadow or youngest Triassic sandstone appears in a

series of serrate ledges between the bridge and the dam at the right.

Mud-cracks on some layers and ripple marks on others tell of wet and dry

seasons at the time they were formed. The route turns right just south

of the Holyoke post office (34.6) and right again into Federal Highway 5

(36.2), which parallels the river.

The road has been built on a terrace which was once the flat bottom of

glacial Lake Springfield (37.8), but at the north end of the city it

descends towards the Connecticut River, utilizing the contact between

the red layers of Longmeadow sandstone and the massive, dark green

Granby tuff with large volcanic bombs that are visible from the road.

The twin entrances to Mountain Park (38 and 38.2) may tempt the motorist

to indulge in an attractive side trip, but there is enough to occupy him

on the main highway. Nearer the river (38.5), a ledge slopes from the

roadway to the railroad tracks and to a series of riffles in the stream.

This is the Smith's Ferry footprint locality (pp. 66-67), and the

widened highway and the entrance to the ledges offer an invitation which

cannot be declined (38.6).

North of the dinosaur tracks, road, railroad and river run parallel.

Lateral roads are few, but there is a gateway (40.2) into the Mount Tom

Reservation. The Granby tuff, which has outcropped persistently on the

west side of the road, rises to a high bluff and then passes eastward

beneath the river (40.6). The underlying second lava replaces it in the

road cuts and is especially conspicuous along the railroad (40.9). The

next dark gray bluff west of the road (41.4 to 41.6) is part of the

Holyoke flow which caps the Mount Tom and Mount Holyoke ranges (see pp.

26-27). Soon it, too, crosses the river to Titan's Pier (pp. 60-61), and

old residents say that a ledge of it outcropped in the river bed at low

water before the Holyoke dam raised the water level. Directly ahead,

southward-dipping beds of conglomerate outcrop on either side of the

road (41.0); these beds underlie the lava forming the gentle southern

slopes of the ranges, and their position beneath the trap can be seen

plainly on the steep northern slopes.

The road through the Mount Tom Reservation rejoins the highway (42.2)

just south of the outlet from the Oxbow Lake (42.3), the upper end of

which also loops 'round and abuts against the highway (42.7). (See

p. 3.) Annual floods inundate most of this section, and even the

banked-up road and railroad periodically go under the swirling waters of

the swollen river. A sign (43.5) announces that the roadway was 13.5

feet below water at the height of the 1936 flood, but it is hoped that

the new dike at the southern limit of Northampton will hereafter turn

the floods away from the lower sections of the city. Federal Highway 5

bears right (44.0), and the road ahead continues into the Berkshire

Trail. Of passing interest is the fact that a well drilled near this

junction penetrated 3,700 feet of Triassic arkose without reaching the

crystalline rock floor. The road crosses the unused bed of Mill River

(44.2) and comes once again to the Court House corner in Northampton

(44.6).

_Belchertown, Amherst, and Northampton_

In our first tour we noted that a road (Route 9) turns right to Amherst

at the south end of the Daniel Shays Highway (21.1), and if we will

return to this junction, it will be worth our while to make the Amherst

run. Just beyond the intersection the highway traverses the level gravel

plain of a nice margin lake (see p. 7) before it descends (22.0) toward

the Lake Hadley plain. Erratic boulders and stone fences are abundant on

the slope, and the bedrock is part of the pre-Triassic complex. One very

interesting pegmatite contains inclusions of contorted schist (23.2).

The road soon leaves the rocky slopes for the gravel plain of Lake

Hadley, but only a short distance northward and westward lie the

Belchertown Ponds, which seem to occupy a large and deep kettle hole

area (see pp. 7-8).

The road winds through pine-clad kame terraces, left on the margin of

the ice which filled the Lake Hadley basin; and where it emerges from

the woods (24.4), the line of hills making the Holyoke Range may be seen

stretching westward in a series of sharp points. These are the

projecting edges of the Holyoke lava flow which resisted erosion after

all the softer sediment and volcanic debris flanking it were removed.

The road to Mount Lincoln turns right at Pansy Park (24.9), and north of

this point the Amherst road follows a kame terrace between the Pelham

Hills on the right, and the former ice-filled bed of glacial Lake Hadley

on the left. Ultimately (27.1) the highway leaves the terrace and drops

to a delta which was deposited in Lake Hadley. The view northward shows

Mount Toby and Mount Sugarloaf outlined sharply, and to the east near

the Orient, the sharp V-shaped notch of the north fork of Fort River

cuts one of the kame terraces. The delta deposit (27.5 to 27.7) shows

excellent fore-set beds in the gravel pit (27.7), and its entire surface

is dotted with ponds which occupy irregular kettle holes (see pp. 7-8).

The highway continues down the delta slope and crosses the Fort River

(28.4). This river established a meandering course upon the bed of Lake

Hadley, but its floodplain is now excavated below the level of the lake

deposits, which form a terrace above the stream. The road passes through

Amherst (30.2) and returns to Northampton (37.4) by the outbound route.

_South Hadley, Amherst, Northampton_

The route 116 north from the road junction at South Hadley Falls (33.2)

also has its points of interest. After it passes over the deeply

dissected deposits in Lake Springfield, it rises above the old lake

level at the Mount Holyoke campus (35.1) and continues at this higher

elevation beyond the Hockanum-Amherst fork (35.9) in the center of South

Hadley. Along the right fork (State Highway 116), which leads to

Amherst, horizontal Longmeadow sandstone outcrops west of the road

(37.1) where the slope to the valley of Bachelor Brook begins. The flat

lake plain extends from Moody's Corner (37.4) to the base of the Holyoke

Range. A gravel road turns right from the highway (38.2) and crosses the

brook one mile east, and from this locality were excavated many of the

excellent dinosaur footprints in the Amherst College collection.

The lake plain ends at ledges of Granby tuff and agglomerate (38.5). The

outcrops east of the road are grooved with glacial striations, and the

fragmental nature of the rock is clearly revealed in the smooth surface.

Lava lies on the tuff west of the road (38.7) and also at the bottom of

the volcanic series at the Aldrich Lake road (39.0). Coarse

conglomerates make recurrent ridges as far as the base of the Range

(39.5), where the road follows a shelf cut into the Holyoke lava flow

just west of the Notch fault. The conglomerate east of this fault was

displaced downward; and as it disintegrates easily, a depression has

been cut into the Range east of the road. The quarry situated at the top

of the Range (39.8) just north of the Amherst town line, has brought to

light many fault fractures that have served the mineral collector well

for almost a century. The Range trail (see pp. 73-75) westward leaves

the highway at the town line marker, and the path eastward follows the

old trolley line northeastward from the scales house.

The route begins its descent (40.2) through a cut in conglomerate, and

the entire northern valley is spread out below: Sugarloaf and Toby close

the eastern side of the view, and hills far up in Vermont form the

background in the northwest. The road quickly reaches the flat plain of

Lake Hadley (40.7), with apple orchards stretching along its gravel

shore line. The Bay Road crosses the highway (41.1) and parallels the

Range from end to end.

The lake deposits fail to conceal many earlier features. Two drumlins

(see p. 9) rise to the east of the road (41.8) near South Amherst. South

Amherst (42.7) is on an island in the old lake; erratic boulders cover

the hilltop, and bare rocks mark the old wave-washed shore. The highway

crosses Fort (or Freshman) River (43.8), and at the railroad tracks

(44.6) it rises to the old lake beach, which is continued in the flat

land on the south side of the Amherst College campus. The route turns

left at Northampton Road (Route 9) and continues to Northampton (52.2).

The Hockanum Road (State Highway 63), which follows the left fork at

South Hadley (33.2), crosses the Lake Springfield sand plain (34.1) and

rises above the lake level beyond Bachelor Brook (34.3), staying at this

higher altitude beyond the junction with the Moody's Corner road (35.3).

The hills directly ahead are tuff, agglomerate and lava, and are

products of the last volcanic episode in this region. Dry Brook (35.6)

flows on the sandstone overlying the Holyoke lava sheet, and the latter

outcrops in the road cuts (35.8) and to the left in Titan's Pier (see

pp. 60-61). The road to the Mount Holyoke House and Titan's Piazza (see

p. 61) turns right (36.0) where the highway breaks through the last of

the lava mass.

The 1936 flood inundated this highway (36.5 to 37.2), and the old

watermark may still be identified by debris caught in the bushes and

left on pasture land. The view upstream from the floodplain (37.0) shows

where the Connecticut is cutting into its eastern bank and causing it to

recede (see pp. 1-2). Soon it will penetrate the valley of Fort River.

The road passes through a woodland on the dissected lake-shore deposits,

but it soon emerges upon the lake bottom and early river silts (38.6).

The Bay Road (39.8) enters from the east just south of the bridge over

Fort River (39.9). The road joins the outbound route at Hadley (41) and

returns to Northampton (44).

_Holyoke, Easthampton, Northampton_

The return from Holyoke (36.2) by way of Easthampton leaves Federal

Highway 5 and rises westward across a ridge of Granby tuff. Several

small lakes (36.7) occupy basins on the friable "second" sandstone

between the "second" lava and Granby tuff, which lie immediately to the

east, and the Holyoke lava, which lies below and to the west. The

sandstone is very thin, and the road shortly begins to climb up the dip

slope of the Holyoke lava sheet. Sandstone crops out below the sheet at

the west base of a low cliff (38.1) which continues northward to the

south face of Mount Tom. The Christopher Clark road through the Mount

Tom Reservation enters from the north at the summit (38.5); it follows a

scenic route under the west cliffs of the Range to its north end at

Mount Nonotuck, where it drops abruptly in a series of hairpin curves to

Mount Tom Junction on Federal Highway 5.

At the junction of the Easthampton and Christopher Clark roads, a

turn-out offers an opportunity to view the Western Upland, within which,

as it makes its way from Goshen and Williamsburg to Northampton, the

Mill River has cut an impressive valley. On the long descent to the base

of the mountain (39.5), the Easthampton road is cut out of coarse

arkosic sandstones, but then it levels off abruptly on the flat plain of

glacial Lake Hadley. The lake sediments continue into the center of

Easthampton (41.3), broken only by the shallow valley of the Manhan

River. From Easthampton the route utilizes the College Highway (State

Highway 10) to Northampton; and its position on the lake beds affords

good views of the Range and of the abnormally broad floodplain of the

meandering Connecticut River in the vicinity of the Oxbow. Just north

and east of the New Haven Railroad's underpass, the river has cut away

the terrace followed by the road, and this low stretch, like the rest of

the floodplain, is subject to frequent inundations.

The road enters Northampton east of the Smith College campus (45.5) and

joins the Berkshire Trail. A right turn at the traffic light leads to

the Court House corner (45.7).

_Northampton, Hadley, Sunderland, Hatfield_

This tour also leaves Northampton by the Coolidge Memorial Bridge, but

at Hadley (3.0) it turns north on State Highway 63 and follows the river

to Sunderland. Here the route recrosses the river, joining Federal

Highway 5 at South Deerfield, and from this point south to Northampton

the road lies almost literally in the shadow of the western upland.

In Hadley (3.0) the road turns north along Center Street and then swings

right at the curve in the Connecticut (3.5). The river bank is lined

with riprap to resist the current and to prevent the river from washing

away a substantial section of the town. Across the stream in Hatfield

the Connecticut very nearly achieved the type of destruction which the

residents of Hadley are trying to escape, and the flood-channel, or

"washout," which was gouged by the swollen stream in the spring of 1936,

may be seen (4.3) on the way to North Hadley. The road approaches Mount

Warner, whose crystalline rocks appear at the south end of a long, low

spur (4.8) on the edge of the river floodplain. Elsewhere along the base

of the eminence, which scarcely merits the name "Mount," the crystalline

rocks are hidden by a terrace, but they crop out on the higher slopes.

The younger red Triassic sandstones are present, too, and they may be

seen dipping steeply westward in the brook bed between the bridge (5.9)

and the dam (6.1) at North Hadley.

Sand dunes appear near the river on the outskirts of North Hadley (6.3)

and extend north beyond Mount Warner (7.0) to the point where the road

drops from the terrace to the floodplain (8.2). Here the former bed of

the river is occupied by a puny brook, which enters the mainstream on

the left. The terrace marking the edge of the floodplain lies close to

the east side of the road for a long distance (8.2 to 9.8) and then

swings a half mile eastward. The road follows a high area between two

abandoned channels formerly used by the river (11.3), until it joins the

Amherst-Sunderland road (11.8) at the southern edge of Sunderland. The

route turns left in the center of town (12.4), crossing the river

beneath Mount Sugarloaf, and it continues on to Federal Highway 5 at the

traffic light in South Deerfield (14.2).

On the trip south from the junction, sand dunes appear east of the

railroad between the Boston & Maine (14.6) and the New Haven crossings

(14.9). The highway is situated on the flat bed of Lake Hadley from this

point to Hatfield. The road to Whately, which turns west at 16.7, offers

some attractions. It forks two miles beyond Whately, and the right

branch leads to the Northampton reservoir and to Haydenville (see

p. 89). The left branch follows West Fork Brook and comes back to

Federal Highway 5 at North Hatfield (19.1). Either route provides a

scenic drive over little-frequented gravel roads.

From the main highway the delta built by West Fork Brook into glacial

Lake Hadley appears as a flat terrace along the western highland (18.2).

The rolling fields (19.7) east of the railroad are dunes which were once

raised by the wind along the old Connecticut channel. Mill River, which

rises near Conway, parallels the highway for 6.1 miles and crosses it

here to enter the Connecticut (20.3). The road approaches the massive

gray rocks of the western upland (20.5), and the Hatfield lead vein (see

p. 64) outcrops in a bluff on the right (20.9). The view south (22.3)

shows the water gap between the Mount Holyoke and Mount Tom ranges. At

the State Police barracks (23.4) the Hatfield road turns left, and a

short distance beyond (23.9), on the west side of the road, is the

abandoned City Quarry. The granite exposed in the quarry contains a

black, radio-active mineral called allanite, and each glistening black

crystal is surrounded by a reddish halo caused by bombardment of the

feldspar by alpha particles.

A road to Florence branches right (24.5) near the railroad crossing, and

one to the Coolidge Bridge turns left across the Boston & Maine tracks

(24.7). A by-pass to the Berkshire Trail (25.6) goes west, and the tour

returns to the Court House corner (26.1).

_Northampton, Cummington, Plainfield, and South Deerfield_

This tour includes a representative section of the Connecticut Lowland,

traverses rugged valleys on the western margin of the lowland, and

crosses a wide remnant of the New England upland. The trip is 58.6 miles

long, and all of it except the last twelve miles moves through rapidly

changing scenery.

The route leaves the Court House corner on State Highway 9, the

Berkshire Trail, following Main and Elm Streets past Smith College. At

the Cooley Dickinson Hospital the road rises from the bed of glacial

Lake Hadley to the Mill River delta, which, despite some dissection,

maintains the same general level through Florence (2.6) to Look Park

(3.4), where a ridge dotted with glacial erratics rises through it. The

road follows the delta margin past the Veteran's Hospital and shortly

(4.3) climbs to the land of erratics and stone fences. The road from

Whately (see p. 88) enters from the right in Haydenville (7.1), and the

Trail continues up Mill River to Williamsburg (8.1). Not far beyond the

center of Williamsburg the road forks left for Chesterfield and right

for Cummington.

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.)
