about 2 miles north of Kings Station. Farther to the north beyond 

 the limits of the sheet at the foot of the eastern slope of Mount 

 McGregor and Palmertown mountain there are extensive develop- 

 ments of kame terraces. 1 



There are a number of isolated groups of hills composed mainly 

 of sands and gravels and of the hummocky aspect characteristic 

 of kame topography. Their locations are shown on the accom- 

 panying map. The group of largest areal extent lies about 2 miles 

 northwest of Milton Center. This appears to be, definitely, an area 

 of isolated, or extramorainal, kames. Another area of hills of 

 sand and gravel of characteristic kame topography is located north 

 of Middle Grove and east of Kayaderosseras creek. It seems prob- 

 able that this area was originally connected with the massive sand 

 formation on the opposite side of the creek and which is continuous 

 with the kame terrace at higher elevation, as described above. It 

 would seem that over this entire region there lay a mass of stag- 

 nant ice and that accumulations of sand and gravel took place both 

 at its western edge (thus forming the kame terrace) and at its 

 southern margin, thus forming a belt of kames, the southernmost 

 extension of which is the group of hills under consideration. 



Recessional moraine. About 3 miles south and southeast of 

 Corinth there is a region marked, by the topography characteristic 

 of terminal moraines. The surface of the country is made up of 

 hillocks and hollows, or ridges and troughs, without order of ar- 

 rangement but forming collectively an irregular belt, extending in 

 a general east- west direction and having a length of about 6 miles. 

 The western end of this belt is now separated from the kame ter- 

 race formation above described by the valley of Sturdevant creek 

 and by a leveled terrace, thickly strewn with cobbles and boulders, 

 east of the creek. This leveled area is unquestionably a portion of 

 the moraine reduced by stream erosion. In its eastward extension 

 the moraine stretches to the base of the region of highlands of 

 which Mount McGregor is the center. Thus, taken in connection 

 with the kame terrace, the moraine originally formed a continuous 

 belt of elevation across the central depressed area. 



The general shape of the moraine in its surface distribution and 

 considered as a whole is that of a series of lobes pointing south- 

 ward, that is, in a direction corresponding roughly to the direction 

 of movement of the ice. In all, there are four lobes. The re- 

 entrant angle south of the moraine between the first and second
