TWENTY-NINTH ANNUAL MEETING. 101 
New Visit. 
In 1895 a new visit was made to the buried moraine in company with Prof. 
F. W. Cragin, of Colorado Springs, and Dr. Wm. Smith. One object of the 
visit was a confirmation of the assertion that the boulders were pressed into the 
south wall of the valley, as described in the ‘‘ fifth bend.’’ By some mischance 
that particular bend was overlooked, showing that a miscount was made either 
on one or both trips; and while the oversight was suspected, it was not posi- 
tively known until the ‘‘cut-off’’ was reached; and it was then decided not to 
retrace. The point was neither reaffirmed nor refuted. 
Another point we desired to know was whether the southwest sides of the 
boulders were more highly polished than the other sides, as observed in the 
moraine near Blacksmith creek (a point mentioned in an article read before the 
Academy of Science in December, 1894.) * 
LEE Moratne. 
The particular portion of the moraine examined was the two-mile north-and- 
south strip east of Burnett’s mound. The statement was not confirmed here. 
The most highly polished side was not oriented in any direction. Directions 
were various and about equal. This may be because the moraine trends north- 
and-south, and the boulders are thus protected from the prevailing winds. 
Observations were limited to the half mile on the Rowles place, along the west 
line of section 23 and just south of the old M. I. Lee place. The ridge here ap- 
pears to be composed entirely of drift, and there are many large boulders. Half 
a dozen metamorphic sandstone boulders were found that were incrusted more or 
less up to one-eighth of an inch in thickness with a brown ferruginous sand. On 
removing this incrustation with a sharp implement and some force, the face of 
the stone was seen to be polished the same, or about as much, as where the stone 
is exposed. If stones had been imbedded in a bank of iron sand during one or 
more interglacial epochs previous to the Kansan epoch, then they were polished 
before they were deposited in the bank of iron sand, and not by dust attrition 
since they arrived here. Is this reading the lesson correctly? Then again, it is 
as reasonable to expect, if they had been deposited together before, they would 
be taken up at the same time in the advance of the ice during the Kansan epoch 
and deposited together here, as that they would be scattered many miles apart 
along our moraine. However, similarly incrusted stones are to be found else- 
where. 2 
This two-mile strip of moraine is nearly level along its crest and does not vary 
in elevation perhaps more than 25 or 30 feet at different points. The highest 
point is near the north end, about half a mile south of the Shunganunga which 
comes close to the north end. The moraine is from 200 to 300 paces across, and 
from 30 to 50 feet higher along the middle or crest than along the sides, where it 
changes to prairie earth containing some drift but no boulders. 
On the Rowles place, on section 23, half a mile south of M. I. Lee’s house, the 
ridge is bisected by a preglacial gap, through which runs a branch of Colby 
creek, flowing northward into the Shunganunga. Its depth is about 85 to 90 
feet ; its breadth 12 to 15 rods at the bottom. It cuts the ridge squarely across. 
The little stream, after passing through the gap, turns to the north. The floor 
of the gap is glacial drift. A new well for stock is dug close to the north bluff. 
The well is about six feet deep. A limestone ledge, two feet thick is at the top 
of the well, at the base of the bluff. The material in the side of the well under 
the limestone ledge is drift. All the earth thrown from the well is drift clay and
