DESCRIPTIO N 



OF THE COUNTRY 



Meek was governed by the features of the country, and the occasional occurrence 

 of loose masses of F. 2 scattered over the surface. It was, however, seen in place 

 on both shores of Missouri Creek, also in Sections 4 and 33. 



In Township 26 north, Range 15 west, F. 2 was observed on both sides of a small 

 stream which runs through Section 2, and in Sections 33 and 34, loose masses of 

 this formation were found near the summits of the hills. In the latter section, 

 this rock was also found in place on the southeast corner, at several points, but 

 did not attain to any considerable altitude. On the north side of Section 1, loose 

 masses were again observed, and in the northwest corner of Section 2 it was seen 

 in place on a small creek, reposing on F. 1. In Sections 3, 24, 13, and 23, the 

 Lower Magnesian Limestone was also observed in place. 



On Section 36, Township 27 north, Range 15 west, F. 2 occurs on both sides of 

 the L'eau Gallee River, near the tops of the highest hills. In Section 35, it was 

 seen on the west side, and the northeast and southeast corners. In the former it 

 is somewhat cherty. In Section 34, large loose masses of F. 2 were found scattered 

 over a hill in the northeast corner. In Section 26, near the top of a hill, two hun- 

 dred and seventy-three feet in height, in the southwest corner, these rocks were 

 seen in large loose masses, somewhat cherty ; but it could not be ascertained how 

 much of the hill was composed of F. 2. In Section 27, loose masses, similar 

 to those in Section 26, were noticed near the summits of the hills, on both sides 

 of the river. In Sections 22 and 26, the Lower Magnesian Limestone was ob- 

 served on the west side of the river; and in Section 16, these rocks were found 

 to occur on both sides. Near the south part of this section, and on the east side 

 of the river, there are hills two hundred and seventy-five feet in height, near the 

 summits of which the Lower Magnesian Limestone was exposed in thick beds. In 

 Section 8, the rocks were seen on either shore of the river for the whole distance that 

 it traverses the section ; and in the northwest corner, the hills attained to the height 

 of two hundred and forty feet, with an exposure of about twenty feet of F. 2 at 

 the summit. In the northeast corner of Section 7, the hills are crowned with loose 

 masses of magnesian limestone, with an occasional exposure of this rock in 

 place. In Section 6, loose masses were seen towards the summits of the hills on 

 the west side of the river, for the entire distance that it courses through the 

 section ; and at a few points the rocks were seen in situ, forming, however, only 

 low ledges, about twenty feet in height. The upper beds of the formation were not 

 observed anywhere in the township, the middle or cherty members being alone 

 exposed. They are not, however, so cherty as the equivalent strata on Rush 

 River. 



None of the beds of F. 1 were exposed in the township, though from the rounded 

 outline of the hills, and the gentle character of the slopes, it is quite probable that 

 this formation constitutes the underlying rock throughout its greater portion. 

 Along the eastern branch of L'eau Gallee River, F. 2 was exposed at various points, 

 and was found to extend as high up the stream as Sections 10 and 11. 



From previous examinations, made by the different members of the Geological 

 Corps, with reference to the lithological appearance of the beds of F. 2 which were 

 lead-bearing, it was ascertained that where the strata were much broken and tra-
