THE NORCROSS BEACHES IN MINNESOTA. 385 



Western, where this beach ridge runs nearly due north, the height of its 

 crest, according to my leveling, is 1,043 to 1,045 feet. 



Continuing northward beyond the Red River, the Norcross shore-line 

 traverses the northeast corner of township 132, range 45, passing west of a 

 small lake which lies a mile south of the Northern Pacific, Fergus Falls 

 and Black Hills Railroad. Thence its course is nearly north-northwest 

 across the next two townships in this range; but in Tanberg and through 

 the next 10 miles to Humboldt (the next township east of Barnesville) it 

 runs in a nearly direct course only a few degrees west of north. On the 

 west side of the very remarkable marshy and springy belt which lies just 

 within the Herman shore-line in Aki-on and Tanberg, the Norcross beach 

 rises as a ridge of gravel and sand a few feet high, forming in considerable 

 part the boundary between the bogs, springs, and numerous watercourses 

 on the east and the firm land, capable of cultivation, on the west. In Tan- 

 berg it passes along the east border of sections 32, 29, 20, and 17, having 

 at its crest a height of 1,050 to 1,060 feet above the sea. 



Close east of the Norcross beach ridge a large spring in the northwest 

 corner of the southwest quarter of section 28, Tanberg, having a diameter 

 of about 15 feet and depth of 10 feet, issues with so strong a cmTent as to 

 throw up the sand at its bottom to a height of 2 or 3 feet into the water. 

 A creek 5 to 15 feet wide and 1 to 3 feet deep, in which many pickerel 

 live, flows from this spring southward along the east side of the beach 

 about a mile, then turning west into the southeast quarter of section 32, 

 where it sinks into the gravelly and sandy ground and is lost. 



About 1^ miles east from Barnesville the Norcross beach is well 

 exhibited at D. D. Daniels's house, in the southeast quarter of section 20, 

 Humboldt, being a low, smoothly rounded ridge of gravel and sand, with 

 the elevation of 1,061 feet above the sea. 



Tiu'ough Riverton and in sections 35 and 26, township 140, range 46, 

 the eroded western border of the delta of the Buffalo River marks the 

 shore of Lake Agassiz at the time of the Norcross beach. 



In the west part of section 24, township 140, range 46, and for 4 miles 

 northward, the Norcross beach lies only 1 mile to a half mile west of the 

 Herman beach, and is about 50 feet lower. The terrace-like area between
