554  . FORMER EXISTENCE OF LOCAL GLACIERS 
tn situ from which they were detached. Now, in the neigh- 
borhood of the White Mountains, we find beside the typical 
or northern drift, large erratic boulders as well as lateral, 
frontal and median moraines. A careful examination of 
these shows beyond a doubt that they came from the White 
Mountains and not from the northern regions, since they 
overlie the typical drift which they have only here and there 
removed and modified. A short description of the facts will 
leave no doubt upon this point. 
The finest lateral moraines in these regions may be seen 
along the hillsides flanking the bed of the south branch of 
the Amonoosuck, north of the village of Franconia. The 
best median moraines are to the east of Picket Hill and 
Round Hill. These latter moraines were formed by the con- 
fluence of the glaciers which occupied the depression be- 
tween Haystack and Mt. Lafayette, and that which descended 
from the northern face of Lafayette itself. These longi- 
tudinal moraines are partieularly interesting as connecting 
_ the erratic boulders on the north side of the Franconia range 
with that mountain mass, and showing that they are not 
northern boulders transpor ted sodthewnidj but boulders from 
a southern range transported northward. But by far the 
most significant facts showing the great extent of the local 
glaciers of the White Mountain range, as well as the most 
accessible and easily recognized, even by travellers not very 
familiar with glacial phenomena, are the terminal moraines 
to the north of Bethlehem village, between it and the north- 
ern bend of the Amonoosuck river. The lane starting from 
Bethlehem street, following the Cemetery for a short distance, 
and hence trending northward, cuts sixteen terminal moraines 
in a tract of about two miles. Some of these moraines are 
as distinct as any I know in Switzerland. They show un- 
mistakably by their form that they were produced by the 
pressure of a glacier moving, from south, northward. This 
is indicated by their abrupt ipei slope, facing, that is, 
toward the Franconia range, wbile their northern face has a
