CAMPBELL BEACHES IK MINNESOTA. 409 



Fergus Falls and Black Hills Railroad a quarter of a mile west of Everdell 

 station. Thence for the next 15 miles its course is a few degrees west of 

 nortli to the vicinity of Manston. 



Through sections 15, 10, and 3, township 134, range 46, and northwai'd 

 in Manston, the Campliell shore-line is mostly ) narked by ;i definite gravel 

 ridge, the land on each side being till. The ridg-e varies in elevation from 

 987 to 992 feet, attaining the latter height 1^ miles southeast of the village 

 of Manston, where it rises 6 or 7 feet from its east base and has a descent of 

 about 10 feet toward the west. 



In Atherton this shore is intersected three times by the railway from 

 Breckenridge to Barnesville. A l)each ridge, for the greater part scantily 

 and irregularly developed, passes northwestward across section 34 an-^l the 

 railway. Thence curving to the north and northeast, it lies close west of 

 the railway for 2 miles, nearly to the Deerhorn Creek. About a quarter 

 of a mile south of this creek it again crosses the railway, from which a spur 

 track turns off to take gravel ballast from the ridge, its excavation being 6 

 to 10 feet deep. For the next 2 miles this upper Campbell l)each runs 

 nearly parallel with the railway and close on its east side to the south part 

 of section 10; and thence, after its third crossing of the railway, it extends 

 3 miles nearly due north to a cemetery about 1.^ miles west of Barnesville. 

 The elevation of the beach crest in sections 15, 10, and 3, Atherton, and 

 also in the cemetery, is 900 to 992 feet above the sea, with a descent of 3 

 or 4 feet on the east and of 6 to 10 feet on the west. 



A second beach ridge, of smaller size, a tenth to a quarter of a mile 

 west of this, with its crest 5 to 7 feet lower, about 985 feet, begins near 

 Atherton Station and is continuous, or nearly so, through section 15 and the 

 south part of section 10. The foot of the western slope of the lower i-idge, 

 at 980 feet, indicates approximately the level of Lake Agassiz when it was 

 formed. A slight elevation of the land, probably amounting to 5 feet, had 

 apparently taken place between the times of formation of these two beaches. 



Both the upper and the lower Campbell beaches are also well exhibited 

 2 to 3 miles north of Barnesville, near the railway bridge over Siebers Creek. 

 In the northwest corner of section 13, Barnesville, less than a quarter of a 

 mile south of this creek, the upper beach, forming an uregular belt of
