Bibliography of Ernst Antevs entry number   Note that the blue contour lines drawn here to show the recession of the glacier's terminus over time are approximate. Over the last 25 years, Gangotri glacier has retreated more than meters ( yards), with a recession of 76 meters (83 yards) from to alone. —Credit: NASA, based on data provided by the ASTER Science Team.

    Manitoba and the neighbouring provinces and states emerged from beneath the ice sheet in a series of advances and retreats. The ultimate extent of glacial Lake Agassiz. Although the lake was never this large at any one time, by the time that it had run its course this much territory had been covered by . Wright and Rubin () date organic matter in the bottom of kettles and in the Anoka sand plain associated with the Grantsburg sub-lobe as 11,, years old. Zoltai () has Lake Agassiz draining into the Superior basin as recently as years B.P. I suspect that some of the potholes are related to these late glacial events.

    Reconnaissance of eastern Ontario regions lying between the late-glacial positions of Lake Iroquois and the Champlain Sea provides new information on ice-flow patterns as represented by striae and other streamline phenomena. This is related to the distribution of ice-marginal deposits and to structurally controlled topography.

The overall pattern of deglaciation was one of spurts of ice recession punctuated by readvances and end moraine building, and acceleration of ice recession over time. The early chronology of deglaciation ( 14 C ka BP, cal ka BP) has been inferred from correlations to Greenland ice core records and varve sequences have been.

Detailed mapping and elevation measurements of glacial lake shorelines in the Flin Flon region has permitted the reconstruction of 6 well-defined levels of Lake Agassiz formed around ka to ka 14C BP.

The stratigraphy of late-glacial, and postglacial deposits and landforms in. The history of Late Wisconsinan glaciation in southwestern Manitoba has been established by identifying and correlating ice-laid lithostratigraphic units in the subsurface.

Five Late Wisconsinan tills are defined on the basis of their texture, mineralogic composition, and stratigraphic position. This analysis is focused on mountain glaciers and smaller ice caps, which have a total area at least x km2.

Although they make up only 4% of the total land ice area, they may have contributed to as much as 30% of sea level change in the 20th century due to rapid ice .Swan or Valley River depressions. Teller (Fig.

Thorleifson () agrees that a major Late Glacial surge of the Red River lobe.A strong correlation emerges between the variable rate of ice delivery to the terminus and the erosion rate, providing quantitative insight into the relationship between ice fluxes and glacial erosion rates.
