En resa till norra tshafvet sommaren 1892, foretagen med understod

the Summer 1892, made with the aid of the Vega Stipend. | 
By AxeL HamBERG. Reprint from Ymer, 1894. 
The author accompanied a Norwegian sealer visiting Beeren Island 
and the Spitzbergen Islands. In King’s Bay a stay of several days 
was made, and the author studied some ice fields, which he named 
Lovéns névés. On the surface of the ice at this place but few small 
lateral moraines were to be seen, but in a fracture of the ice an inner 
moraine was observed. This consisted of about ten strata of assorted 
gravel and sand alternating with layers of ice. It was evidently a 
medial moraine in the lee of a projecting low mountain top, seen 
several miles inland. It is stated that similar features are common in 
the ice fields of these arctic islands. ‘The author suggests that, if the 
ice were melted away, such moraines would give rise to structures much 
resembling asar, both as to the contained material and as to the form 
and direction of the resulting topography. At one place some of 
these deposits were seen extending a distance at right angles away 
from the ice margin and resembling somewhat the Scottish kames. 
The névés were composed of bedded ice, in some places extending out 
in the sea. In several instances it had been melted away under the 
water and marginal blocks had evidently been detached by their own 
weight, leaving the edge of the ice standing in vertical smooth walls 
as if “cut off with a knife.” 
A number of photographs were taken with a camera fitted for 
photogrammetric measurements and a map constructed from these 
photographs accompanies the paper. The névés represented on this 
map are seen to occupy valleys among several small groups of hills 
and extending to within less than a mile from the shore. The front 
edge of the ice sometimes forms an evenly rounded curve and some- 
times a vertical cliff from 60 to 100 feet high. It is suggested that 
this difference in the behavior of the terminal edge (when resting on 
the land) may be due to a difference in the morainic material of the
