THE EMEEADO BEACHES. 455 



Euclid and 4 miles east of Augus. In the southeast })Hrt of Ang'us Town- 

 ship and the southwest part of township 153, range 46, its beach deposits 

 of gravel are somewhat irregularly accumulated in three belts lying on an 

 ai'ea of till and separated b)^ intervals of about 1 mile and a half mile in 

 order from east to west. The crests of these short gravel ridges vary in 

 elevation from 900 to 905 feet, their higher portions being usually 3 to 5 

 feet above the siirface on their east side and 6 to 8 feet above the land 

 next west. 



Twelve miles north of Angus a short beach ridge of gravel and sand, 

 having neai-ly the same height with the foregoing, was noted on the east 

 edge of section 15, McCrea, close south of a creek tributary to the Snake 

 River. Again, 4 to 5 iniles farther north, a broad, irregular sand beach, 

 with crest at 905 feet, being 3 to 5 feet above the general level, runs along 

 the east line of section 22, Alma. It reaches a mile or more south from the 

 Middle River, and is a mile west of the Hillsboro beach. Its surface has 

 been somewhat changed into small ridges and hollows liy wind action at 

 some former time, but it is now wholly covered by grass. Thence the 

 Emerado shore runs nearly due north through Wanger and Augsburg, 

 townships 157 and 158, range 47, as shown by their contour; but it has not 

 been traced there nor in its farther course, which is slightly west of north 

 through Kittson County to the international boiuidary. 



In North Dakota the Emerado shore-line runs nearly along the Great 

 Northern Railway by Harwood, Argusville, Gardner, and Grandin, and 

 within 1 to li miles east of Kelso, Alton, and Hillsboro; but most of its 

 course is not distiuctlv traceable on the flat surface of fine silt which is 

 crossed in this distance of 30 miles. Through the next three townships 

 north of Hillsboro, passing Cummings and Buxton, it lies 1^ to 2 miles 

 east of the railway, but approaches within about 1 mile at Reynolds. The 

 Emerado shore here traverses a large area of till, Avhich reaches eastward 

 across the Red River Valley. On this more favorable surface it is doul)t- 

 less clearly marked, like the next higher Hillsboro shore, by a well-defined 

 beach ridge, or in part l)y a low, eroded escar})raent. 



The railway intersects this beach lidge 1.^ miles north of Reynolds, 

 its crest being' about 900 feet above the sea, with descent of 3 or 4 feet
