The eskers described in this paper have formed on the surface of cold ice at the margin of the Antarctic ice sheet. The location, orientation, sedimentary properties and field relationships of the eskers are described and a model of their formation
This paper discusses a technique for mapping the area coverage of sea ice regardless of a cloud cover. Data from the AVHRR sensor of the NOAA-9 satellite were recorded on 22 May 1988.

The objective of this paper is to present the general concepts that have been developed and used to explain the general pattern of growth and decay of the Cordilleran Ice Sheet.
Glacial ice-flows on the islands of Bornholm and Christianso, Denmark
This paper contains results from studies of ice flow directions on the islands of Bornholm and Christianso, Denmark, as indicated by striae and other marks of glacial erosion on the bedrock surface.

Quaternary sandstones and conglomerates found on the valley-sides of the lower Vistula River have been identified as a product of precipitation of CaCO3 under stagnant Middle-Vistulian ice sheet. The trigger mechanizm of precipitation of CaCO3 has
been attributed to the degassing of CO2 from carbonate-saturated pressure pore water at the bottom of desintegration crevasses and fissures of the stagnant and down-wasting ice sheet. - (DG)
Geomorphologic and lithologic evidence for an expanded mountain ice sheet on Mount Kenya during the early Quaternary
The analysis and interpretation of pre-Brunhes (>.73 -.79 my) glacial landforms in the Nithi River Basin, on the eastern flank of Mount Kenya, provide evidence for the dynamics of early Quaternary ice. - (L'A.).
On September 16th, 1986, an ice avalanche from a hanging glacier near the K2 peak at 7 800 m, Karakorum, triggered a massive avalanche of ice and snow. Ice and snow, impacting on the path, formed a dust cloud at the advancing tip. On the basis
Mass wasting on valley-side ice-cored moraines, Boundary Glacier, Alberta, Canada
This paper describes and explains the mass wasting events on the basis of meteorological conditions, morphology of the moraines, and the ice-core. It is proposed that ice-core degradation following decoupling of the moraines from the glacier
Laurentide ice sheet extent inferred from stable isotopic composition (O, C) of ostracodes at Toronto, Canada
The data of this paper show the potential for using isotopic analyses of ostracodes to learn about the isotopic composition of terrestrial meltwater from the Laurentide Ice Sheet. These midcontinent data are especially valuable because they help
to constrain the relationship between ice volume over the North American continent and 18O of seawater.
