section 8, Medford, and sweeps northeast and north through the west half 

 of section 4, and thence northwest aiad west through sections 32, 29, and 

 19, Vernon, and sections 13 to 16, Norton, to a group of morainic hills 

 about 75 feet high, a mile northwest of Gait post-office. Between this 

 curved moraine and the nearly parallel northern part of the preceding, 4 

 miles distant to the south, tlie surface is very smooth, undulating till, rising 

 slowly toward the west. 



These moraines, witli their east base at 1,185 to 1,170 feet above the 

 sea, formed the west shore of Lake Agassiz at its highest stage for nearly 

 7 miles between the Middle and North branches of the Forest River. The 

 North Branch intersects this shore-line near the center of section 20, Ver- 

 non, close to the southwest end of Ramseys Crroves, which extend thence 

 about a mile along this watercourse in the north part of section 20 and the 

 southeast quarter of section 17. The stream in these sections has no valley, 

 only a channel 20 to 30 feet Avide and 10 feet deep. 



Golden Valley, on the north line of sections 4 and 5, Vernon, lias an 

 elevation of 1,185 to 1,195 feet, showing an ascent of 10 feet from east to 

 west in its width of 2 miles. About the same transverse slope, raising 

 the west side of this valley 10 or 15 feet above its east side, is found along 

 its whole extent of 18 miles, from the North Branch of Forest River to the 

 Middle and North branches of Park River. In the north half of Vemon, 

 and thence northward, the width of this valley varies from 1 1 miles to only 

 1 mile. It is flat, and consists mainly of clay, free from gravel; but wells 

 find gravel intermixed with the clay, probably till, at a depth of a few feet, 

 and about 20 feet from the surface they sometimes encounter a water- 

 bearing stratum of gravel, chiefly made up of Cretaceous shale. 



Natural surface at the southwest corner of section 27, Golden, 1,191 

 feet. Highest part of Golden Valley south of the South Branch of Park 

 River, along the north line of sections 27, 28, and 29, in this township, 1,199 

 feet on the east to 1,211 feet on the west. Surface at schoolhouse on the 

 west side of the northwest quarter of section 21, 1,207 feet. 



South Branch of Park River at the bridge near the middle of the 

 north line of section 21, Golden, 1,170 feet, approximately; liottom land 

 about a quarter of a mile wide, 10 to 15 feet above the stream; crest of
