GLACIAL DRIFT. 223 
Baker's River and Winnipiseogee Movement. This is an interesting 
example of a movement seemingly both local and hardly separable from 
the action of the continental sheet. It starts with a south valley in Ben- 
ton, curves to the east with Baker’s River valley in Rumney, extends 
nearly due east over Squam lake and Sandwich, and then enters the val- 
ley of Winnipiseogee lake, merging into the normal south-east course 
after leaving this hydrographic basin. Allusion has been already made 
to the latter part of its course (p. 121 ef seg.). The movement down the 
upper Pemigewasset may be regarded as a branch of this. 
On the summit of Moosilauke the striz run S. 22° E., a course less 
easterly than is common over the high mountains of the state. This 
corresponds with the direction through Warren and Wentworth, save a 
few local tributaries in Warren mentioned in the table. The easting 
seems greater than the proper course of the valley; but a correspond- 
ence was noted between the direction of the strize and of the depression 
when the observation was recorded. The numerous observations in 
Rumney indicate a gradual bending of the scratches in complete agree- 
ment with the change in the course of the valley. On the south side, 
the south-east course does not reach the top of the rim, as the directions 
in Groton on the ridge between Baker's river and Cockermouth brook 
are S, 22° and 32° E. The glacier was certainly 500 feet thick, and prob- 
ably not much more at this point. In the west part of Plymouth and the 
south-east corner of Rumney are remarkably fine examples of striation 
and embossment of the ledges. I hardly think a finer place could be 
found for a photographic representation of these phenomena than of the 
east base of Hawks mountain in Rumney. A spur of the hill projects 
into the valley, which was struck powerfully by the ice as it descended, 
beautifully embossing the schists and scoring the domes with striz. One 
ledge has numerous large blocks of stone on top, some measuring as much 
as 20 feet long, 10 wide, and 8 high. Further west the mural striated 
surfaces are common, as between A. Kelley’s and J. Davis’s houses. 
On the north side of the valley two elevated ranges come close to the 
river,—Rattlesnake and Stinson mountains,—which are precipitous for 
two hundred feet. On these steep sides striz are often visible, though 
much of the rock containing them has fallen to the base of the hill.
