Glacial Action on the Coast of Greenland. — Barton. 383 
of a steeper slope on the west and a more gentle slope on the 
east. The Ekaluit valley contains no glacier in tlie main 
valley, but the valleys tributary to it on the south nearly all 
have glacial tongues descending directl}'^ from the ice-cap. 
These all show evidence of diminution so far as visited. The 
main valley has well defined lateral moraines of an extinct 
glacier on its southern side, which have been cut through by 
the streams from the present lateral valley glaciers to a depth 
of about forty feet without reaching the bed rock below. 
On the nunatak, between the Great and Little Karajak gla- 
ciers, at the head of Karajak fiord, the highest point, given on 
the chart as 1,260 feet above the sea, but in reality much 
higher, presents a series of most typical roches laoutonnee.s, 
with motion about parallel to the fiord, as before. On the 
peninsula of Anat, northwest of the Itivdliarsuk glacier, very 
fine roches nioutonnees occur on the highest point, about 3,100 
feet above the sea, with the motion parallel to that before 
mentioned. P^rratics are numerous over all the region sur- 
rounding the Karajak and Itivdliarsuk fiords, consisting prin- 
cipally of gneiss, which is the underlying rock of this whole 
region. On Anat, hovv'ever. large numbers of limestone boul- 
ders occur, with also man}' of a sandstone closely like the 
Triassic of the Connecticut valley. These do not occur in situ 
outside of the ice-cap and must underlie it somewhere inland. 
Old lateral moraines occur along the mountain sides at 
various elevations above the present level of the Great and 
Little Karajak and Itivdliarsuk glaciers, indicating the former 
greater volume of these. A small valley cutting across the 
southern corner of Anat, the bottom of which in its upper 
portion has about the same elevation as the present surface of 
the Itivdliarsuk glacier, contains lateral moraines, showing 
that this glacier once sent a tongue down this valley to the 
sea, making a nunatak of the extreme south point of Anat. 
At various places along the sides of the Karajak and Itivd- 
liarsuk fiords, at an elevation of perhaps 500 feet, are well 
defined lateral moraines. These are especially well shown on 
the islands of Umanak and Ikerasak, at the foot of the peak on 
each island. These peaks rise almost vertically above the 
rounding of the main mass of the islands to elevations of 
3,100 and 2,500 feet, respectively, both presenting sharply an-
