south of the ra^-iue. In the northwest quarter of this section 12 and the 

 west edge of the soiithwest quarter of section 1, a well-developed beach, 

 in part consisting of two parallel low ridges, has an elevation of 1,170 to 

 1,177 feet, and in the east edge of section 2, continuing northward, its 

 elevation is 1,177 to 1,184 feet. Its eastern slope falls to 1,170 feet witliin

Great Northern Railway at Park River depot, 998 feet above the sea; 

 natural surface at the southeast corner of section 23, Golden, on the road 

 leading west from Park River, 1,178 feet. The crest of the upper Her-

 1,192 feet. This is a typical beach ridge of sand and gravel, with pebbles
