SHORE WEST OF THE ELK AND GOLDEN VALLEYS. 



(plates XXIX AND XXX.) 



Thi'ougli section 32, Elm Grove, the ujiper beach runs northwesterly, 

 its elevation beino- 1,160 to 1,163 feet above the sea. Its material is coarse 

 gravel, with pebl)les up to 6 inches in diameter, in part accumulated as a 

 ridge 10 or 15 feet above the land at its base northeast and 5 to 8 feet 

 above its southwest base, and in part lying on the flank of swells of very 

 stony till, the crests of which are only 5 to 10 feet higher than the beach. 

 This till or raorainic drift contains a nuiltitude of granitic and limestone 

 bowlders up to 1^ feet in diameter, but few or none of larger size. In the 

 rolling till which rises thence westward to 1,250 or 1,300 feet within 2 

 or 3 miles are many granitic bowlders up to 5 feet or more in diameter, 

 exceeding the usual proportion in the till of this region. 



In the north edge of section 32 and the south part of section 29, Elm 

 Grove, this beach is the terrace-like border of a nearly level tract of sand 

 and gi'avel an eighth of a mile or more in width, at an elevation of 1,171 to 

 1,173 feet. The bordering slope is beach gravel, with its base at 1,155 

 to 1,158 feet; but the slow descent thence eastward is till, somewhat 

 eroded by wave action and having many small and large granitic bowlders 

 up to 4 or 6 feet in diameter strewn on the surface or partially covered 

 by the soil. In the northeast quarter of section 30 this upper Herman 

 beach is typically developed, being a gracefully rounded ridge of sand and 

 gravel, 25 or 30 rods wide; crest, 1,165 to 1,166 feet; foot of eastern slope, 

 1,150 feet; depression west, usually 2 to 5 feet, beyond which is a slowly 

 ascending' area of smooth, undixlating- till. 



Upper beach through section 19, Elm Grove, a low, rounded ridge of 

 sand and gravel about 25 rods wide; crest, 1,166 to 1,168 feet; base of its 

 east slope on the north line of this section, 1,158 feet. In the southwest 

 quarter of section 18 this beach is cut by the South Branch of the Turtle 

 River; its elevation in this section south of the stream is 1,167 to 1,168 

 feet. There is no considerable valley here, and the creek runs only in 

 spring or after unusual rains, being reduced to stagnant pools during the 

 rest of the year. Within 2 miles southeast, however, it becomes a living
