of the forest cover or with artificial surface drain- 

 age. 



In the Upper Peninsula, the dip of the paleozoic 

 rocks in the eastern portion of the district is from 

 north to south, the divide, as already stated, being 

 rather close to Lake Superior. This affords condi- 

 tions favorable to artesian wells along the southern 

 zone approaching the shore of Lake Michigan; and, 

 in fact, such wells have been found at or near 

 Menominee, Escanaba, Gladstone, Manistique, and 

 St. Ignace, at Newberry in the Taquamenon swamp 

 area, and at Ewen, in Ontonagon County, but, so 

 far as is known, not near the Lake Superior shore, 

 although an attempt was made to secure such a 

 well at Grand Marais. A. C. Lane, State Geologist 

 in 1903, considered portions of the Lake Superior 

 shore west of Marquette, and west of the copper 

 range, favorable to such wells, but in the main this 

 region is free from them. On the copper range 

 itself and the iron ranges, the geologic structure is 

 unfavorable to their existence. At some points, as 

 along the bluffs facing Portage Lake on the Kewee- 

 naw Peninsula, springs are abundant and of ample 

 flow.^ 



' For analvses of waters from wells throughout the State, 

 see the Report of the State Bd. of Geol. Survey for 1903, 

 which also contains much data in regard to the water sup- 

 ply of the State. Other data may be found in other reports 

 of the Geol. Survey and in special "Water Supply Papers,"
