272 PLEISTOCENE OF INDIANA AND MICHIGAN. 



The Deanville kames are roughly divided into three large masses. The largest mass 

 stands on the east side in sees. 27 and 22; a somewhat smaller one joins it closely on the south- 

 west in southwestern sec. 27; the third lies a mile west of the first, mostly in sec. 28, but partly 

 in sec. 21, Burnside Township. By aneroid measurement from Brown City the eastern knob 

 has an altitude of about 1,060 feet above sea level, the western one 1,030 feet, and the southern 

 one a little less. The divide on the floor of the Imlay channel 1 i miles southwest of the kames has 

 an altitude of about 790 feet, so that the highest knobs rise about 270 and 240 feet, respectively, 

 above that level. They rise nearly 200 feet above the general level of the surrounding country. 



Along the east side of the eastern knob there is a well-marked depression or foss into which 

 the descent is steep. This depression was evidently occupied by the ice and the steep slope 

 marks the contact of the ice mass. 



The longer axes of all three hills are northwest and southeast, or in accord with the trend 

 of the moraines, to which they seem to belong. As already noted (p. 263), two well-defined 

 moraines run southeast from about 3 miles southeast of North Branch. Their crests are only 

 a mile apart, but they run as two distinct individuals southeastward to the vicinity of the 

 kames. If the kames were inset a little from the front of the ice, as seems probable, their 

 relations and the interval between them seem to accord well with the two moraines referred to. 



At one time the railroad ran a spur from Brown City to the north end of the eastern kame 

 and a large amount of gravel was taken out for ballast. The pit at the time of the writer's 

 visit, however, was old and showed few details of structure, except that it had a great depth 

 of coarse gravel and large numbers of bowlders. 



MAYFIELD KAMES. 



The Mayfield kames stand in the northwest corner of Mayfield Township, Lapeer County. 

 The highest knob, which reaches an altitude of 950 feet, is in sec. 7, and is adjoined by several 

 smaller kames, especially on the southeast. North and northeast of the high knob a jumbled 

 country of about a square mile is covered with knobs and basins and very pronounced short 

 esker ridges trending northwest and southeast. The highest knob is covered at its top with 

 coarse gravel and pebbles and is steep sided and narrow topped. The lower ground among 

 the esker ridges is unusually rough. 



This deposit lies in the trend of the Otter Lake esker and it seems quite likely that it was 

 deposited by the same glacial stream at an earlier stage of retreat. 



GOODLAND KAME. 



Southwest of the Deanville kames, on the west bank of the Imlay channel, stands the Good- 

 land kame, a double-topped kame of large proportions but of somewhat lower height. From 

 the trend of the moraines this kame appears to have been produced by the same glacial stream 

 that made the Deanville kames, but at an earlier stage of retreat. 



About 2 J miles northwest of this kame, and standing also on the west bank of the Imlay 

 channel, there is another large kame which reaches about 1 ,020 feet altitude (aneroid) . 



JUNIATA KAME. 



In the highest part of the Juniata moraine on the north line of sec. 2, Fremont Township, 

 Tuscola County, a large kame known as the Juniata rises considerably above the surrounding 

 country, but its altitude was not measured. It is somewhat elongated toward the southeast. 

 East of this 1J miles a broader knob rises still higher and appears to be partly of the nature of 

 a kame but partly morainic. A pit on the flank of this hill showed bowldery till distinctly 

 overlying clean cross-bedded gravels and suggested an overridden kame.
