 Kettle Hill, close south of Swan Lake. 



BEACHES OF THE EMERADO STAGES. 



The Emerado shore-line, approximately 885 feet above the sea, crosses 

 the Red River between Kragnes, Minn., and Harwood, N. Dak., a few miles 

 north of Moorhead and Fargo; but its course has not been traced for the 

 first 50 miles thence northward to the vicinity of Crookston, Minn., and 

 Reynolds, N. Dak Through both of these States it appears as a single 

 shore-line, and is perhaps tlie one most clearly traceable of all that belong 

 to the time of northeastward outflow. The crustal uplifting of this part 

 of the lake 1)asin had become very slow at the time of formation of the 

 Emerado beach, but in Manitoba a somewhat rapid ujdift Avas in progress, 

 increasing in amount from south to north, and two beaches there, separated 

 by a vertical interval of 10 to 20 feet, seem to represent the single beach 

 farther south. 



In the west part of sections 17, 8, and 5, Crookston, a beach ridge of 

 the Emerado stage was traced 2 miles in a nearly due-north course. Har- 

 vey Cook's house, in the south edge of section 8, is built on its toji, which 

 ranges in height from 898 to 902 feet above the sea, having a descent of 

 10 or 12 feet on the west and half as much on the east. About a mile 

 northwest from the north end of this beach irregular and short gravel and 

 sand ridges, accunuilated on an area of till, mark this shore on the Great 

 Northern Railway, and extend thence close along- its east side 2 miles north- 

 ward to Shirley, the elevations of their crests being 905 to 910 feet. 

 Portions of these deposits have been excavated for railway ballast. 



From 1 t(i 2 miles north of Shirley the Emerado beach is a typical 

 and continuous gravel ridge, with crest at 910 feet, approximately, rising 

 about 5 feet above the adjoining surface of till. Here and through the 

 next 3 miles northward the shore lies an eighth to a half of a mile east of 

 the railway. It continues in a nearly due-north course through the west 

 edge of Belgium and of township 153, range 46, passing 1 h miles east of
