(b) Occasionally small angular pieces of white quartz in the 
soil for several miles along the river bank. No pebbles of 
other rock species exposed in many holes four feet deep. 
(c) Another small pocket of quartz fragments and flakes 
buried in soil from two to six inches beneath the surface. 
These are not generally distributed over an extensive area, 
but are in small pockets or bunches evidently derived from 
pebbles picked out of the river bed at the foot of the bank, and 
roughly fractured close by, the flakes now found being the 
refuse rejected, the remainder of the material having been re- 
moved to the village for finishing. As the fragments occur in 
the surface portion of the Modern flood-plain, their age is not 
very great. 
Returning to the town and proceeding southward on the 
road from vVest Little Falls, we traverse the Glacial sand-plain. 
Small flakes and other sharply angular quartz fragments are 
of frequent occurrence. Indeed, for a distance of many miles 
nearly every step brings some into view. Here and there they 
increase in abundance, and scores may be in sight at one time. 
These apparent "pockets" are usually encountered when the 
road approaches close to the river. A few will be mentioned 
later. 
At the west side of Pike rapids a very interesting archae- 
ological locality was discovered. Here there are three well- 
defined terrace planes developed. The higher one is the Glacial 
plain of modified drift (sand and gravel), and is about twenty- 
six feet above the river. The next is the ordinary flood-plain, 
composed of coarse cobble and boulders below and horizon- 
tally stratified sand above. It intervenes between the Glacial 
terrace and the river at the rapids, and rises eleven feet above 
the latter. At some distance below this place there is a third 
terrace plain developed consisting of a flat, swampy, non-tim- 
bered flood-plain about two feet above the river. 
On the upper plain near its edge there are anywhere within 
a quarter of a mile of the rapids, frequent quartz fragments, 
sometimes in bunches, but usually widely and nearly uniform- 
ly disseminated. There are many very small chips. At the 
excavation made by Maj. Pike in constructing his stockade, 
they appear in the banks. They are also seen at intervals in 
the road between the Little Two river and Swan river. On
