 erse to Lake Winnipeg being 315 miles.

 its valley i 

 one Lake, 



3. The valley of Red River, after narrowing much, is still 46 

 miles wide on the 49th parallel, and, for a long distance south 

 of this parallel, it has an average width of 30 miles (Gen. War- 

 ren's map and G. M. Dawson's statement) ; toward Lake Trav- 

 erse it narrows rapidly, is a mile wide along this lake, the sides 

 rising abruptly from the borders of the lake; beyond this lake, 

 southward, it continues on, one to two miles wide, as the valley 

 of the Minnesota River; and, where it joins the Mississippi, the 

 vallev has four times the width of the Mississippi vallej r above 

 the junction (Gen. Warren). 



4. All now agree that the wide part of the valley which 

 stretches northward from Lake Traverse is lake-bottom prairie, 

 that it was adopted by the Red River, not made by it 

 (Dawson); and that the part south of this lake, is, as General 

 Warren first showed, the deserted highway of the outflowing 

 river and lake. 



5. The Red River lake-bottom valley is bordered much of 

 the way by abrupt sides rising 100 to 200 feet to the top of a 

 terrace-olain or plateau; and. similarlv. the Minnesota tdiannel 

 has sides usual I v I onto ].>n (Wt in height.
