GLACIAL DRIFT. 237 
interested in the facts may readily find them without a guide. The ground to the north 
of Bethlehem slopes gently northward, and is not wooded for about half a mile from 
the street. Following the lane above mentioned, the first moraine reached skirts the 
edge of the wood, and is near the houses of Mr. Phillips; there are four others more 
or less distinct before reaching a little trout brook called ‘‘ Barrett's brook.” The lane 
descends more rapidly towards the brook than before, and where the descent begins to 
be steep the eye commands the space between the brook and a higher ground on which 
stands a house owned by Henry McCulloch. Over that interval six very fine moraines 
may be counted, one of which is perhaps the finest specimen of a terminal moraine I 
have ever seen. Beyond McCulloch’s there are five more, not quite as distinct. The 
ground beyond the termination of the glacier of the Rhone in Switzerland is celebrated 
for its many distinct concentric terminal moraines ; but here we have a field over which, 
within the same area, a larger number of such moraines may be seen, and I believe 
that a pilgrimage to this spot would convert many a skeptic to the true faith concern- 
ing the transportation of erratic boulders, especially if he has seen the glacier of the 
Rhone, and can compare the phenomena of the two localities. 
The Littleton road from Bethlehem, and the roads to Franconia Notch from both 
these towns, frequently intersect terminal moraines. Those familiar with the topog- 
raphy of the Franconia range, and its relation to Picket hill and the slope of Bethle- 
hem, will at once perceive that the glacier which deposited the front moraine to the 
north of Bethlehem village must have filled the valley of Franconia to and above the 
level of the saddle of Picket hill, making it at least fifteen hundred feet thick, if. not 
more; thicker, in short, than any of the present glaciers of Switzerland. It will be 
observed, also, that as soon as the northern portion of that glacier had retreated to the 
wall which encircles the Franconia valley on the north, the glacier occupying hence- 
forth a more protected valley within the ranges must have made a halt, and accumu- 
lated at this point, that is, south and west of the saddle of Picket hill, a very large 
terminal moraine. This moraine actually exists to the present day, and is one of the 
most characteristic features of the distribution of erratics in these regions. From the 
moment the glacier was reduced to the level of Franconia bottom, it must suddenly have 
vanished entirely from the whole valley ; and thus it happens that no other large termi- 
nal moraines are seen between that just mentioned and the higher range of Franconia. 
Moraines similar to those observed on the northern side of the White Mountains 
exist also on their southern side in the vicinity of Center Harbor. Lateral moraines 
may be traced at the foot of Red hill, a little above Long pond; also, along Squam 
lake. Median moraines are very distinct near Center Harbor hotel. Terminal mo- 
raines are also numerous near Center Harbor, and in the neighborhood of Meredith. 
At the southern end of Red hill the lateral moraines trend westward, and show their 
connection with the terminal moraines. These facts, taken in their relation with those 
enumerated above, show that there were local glaciers on the southern as well as the 
northern slopes of the White Mountain ranges, moving in opposite directions,—those 
on the northern slope moving northward, and those on the southern slope moving
