ing some well-striated pebbles. It rests on basalt which has a 

 polished surface, but is not distinctly striated. It is overlain by 

 20 feet of fine sandstone, which, in turn, is covered by extremely 

 brecciated basalt. 



Near this point at the top of the cliff, at an altitude of about 

 1,200 feet, remnants of a fourth indurated ground-moraine were 



found. A deep gorge prevented 

 close examination of this bed, 

 which differs slightly from the 

 others. It rests directly on the 

 truncated columns of a basalt 

 flow, and seems to have sections 

 of these same columns caught up 

 in it, and but slightly rounded. 

 The bowlders are larger than in 

 any of the other ground-moraines, 

 several being 3 feet in diameter. 

 Where seen, it was not overlain 

 by basalt; hence it is not neces- 

 sarily Tertiary in age. 



Another, somewhat similar sec- 

 tion appears on the face of the 

 Botnselvens Kloft, a deep gorge 

 entering the eastern end of the 

 Botnsdalr on the northern side. 

 The section is shown in Figure 8. 

 It is impossible to attempt any definite correlation, but unless the beds 

 have been disturbed by faulting, of which there is abundant evidence 

 in the Skorradalr, a neighboring valley, the moraines here shown 

 should correspond approximately to the third moraine of Fig. 3. 

 The stratified material above the upper moraine appears to be over- 

 lain by basalt farther to the eastward. The two moraines have 

 extremely uneven upper surfaces, as if there had been great irregu- 

 larity in their upper surfaces as deposited, or as if they had under- 

 gone considerable erosion between the time of the retreat of the ice- 

 sheet and the deposition of the sandstone and conglomerate above 

 them. The upper surface of the basalt flow between the two
