and in the northwest qnarter of" section 26, this township, 1,042 feet, with 

 descent of about 5 feet on each side. Crossing next the northwest part of 

 Logan, its crest is at 1,043 to 1,048 feet. 



Between a half mile and 1 mile soiith of Norcross this Ijeach is admi- 

 rably developed, the elevation of its higher portions being 1,045 to 1,048 

 feet, from which there is a descent of 3 to 5 feet eastward and of 10 feet 

 westward. It is a massive gravel and sand ridge, about 25 rods wide, 

 including its slopes, lying on till. 



Nearly the same features characterize it also at Norcross station, where 

 its height is 1,041 feet. There is a depression 3 feet lower on the south- 

 east, and the surface 10 to 15 rods northwest from the top of the beach, on 

 the side where the lake was, has a height of 1,034 to 1,036 feet. Thence a 

 .very smooth plain of till descends to Tintah, Campbell, and the Red River 

 at Breckem-idge. About 50 I'ods northeast from Norcross station the beach 

 attains its greatest height in this village, 1,045 feet. It is a rounded low 

 ridge of sand and gravel, lying on an area of till, and closely resembles the 

 Herman beach, which lies nearly parallel with it at a distance of 3 miles 

 to the east. 



Thence northward the course of the Norcross beach has been mapped, 

 mostly without leveling, to the Red River, which it crosses near the north- 

 east corner of section 31, township 132, range 44, in the west edge of 

 Ottertail County. Tlii'ough this extent of about 25 miles the Norcross 

 shore-line is marked almost continuously by a distinct beach ridge, 3 to 5 

 feet above the land on the east, and twice as high above the adjoining 

 surface at the west which was covered by the lake while this beach was 

 lieing formed. Its distance from the Herman beach on the east varies 

 mainly from 3 to 2 miles, but between 1 and 5 miles south of the Red 

 River the two beaches are only 1 mile apart. 



Where the Norcross beach is crossed by the road from Fergus Falls to 

 Campbell, near the west line of section 29, Western, it has an elevation 

 very nearly 1,045 feet above the sea. It is a wave-like ridge of sand and 

 gravel, about 15 rods wide, with nearly flat surfaces of till or bowlder- 

 clay on each side. In crossing it the ascent from the east is about 5 feet 

 and the descent toward the west about 10 feet. In sections 19, 18, and 7,
