Glacial and paraglacial history of the Troutbeck Valley, Cumbria, UK: integrating airborne LIDAR, multibeam bathymetry and geological field mapping [PDF]
, 2014 High resolution airborne LiDAR (light detection and ranging) and multibeam bathymetry data, supplemented by geomorphological and geological field mapping are used to derive the glacial and post-glacial history of Troutbeck Valley (English Lake District ...

The diamictons of Río Blanco basin, Cordon del Plata, Mendoza
, 2020 Both the sediments and the geomorphic setting of the diamictons along Rio Blanco on the piedmont east of the Cordon del Plata indicate that they could not have been deposited there by a glacier tongue, as I and several earlier observers have suggesred Rather, they must have been deposits of long-runout debris flows, as argued by Polanski.

The Saint-Narcisse morainic complex and early Younger Dryas events on the southeastern margin of the Laurentide Ice Sheet [PDF]
, 2007 The Saint-Narcisse morainic complex extends over 750 km along the southern margin of the Laurentian Highlands in Québec, north of the St. Lawrence Valley, between the Ottawa and Saguenay Rivers. To the east, the Laurentide Ice Sheet margin was located in

Boreas, Volume 54, Issue 4, Page 711-728, October 2025.Here we report on the properties of a glacial sediment succession including various till facies and some subglacial meltwater deposits from a site in central Poland close to the outermost extent of the Scandinavian Ice Sheet during the last glaciation.

The role of shallow banks and marine ice domes in marine‐based ice‐sheet deglaciation
Boreas, Volume 54, Issue 4, Page 649-671, October 2025.Marine‐based ice sheets are susceptible to collapse and faster retreat than their land‐terminating counterparts. One of the key factors contributing to the relative stability of marine‐terminating ice sheets is the presence of shallow bathymetric banks and islands acting as pinning points for the ice sheet.

Formation of De Geer Moraines Deposited Subglacially, Central Québec [PDF]
, 1995 This paper presents a model for the genesis of De Geer moraines in the Chapais and Radisson areas, Québec. The model is mainly based on faciès and deformation structure analysis.

Boreas, Volume 54, Issue 4, Page 590-624, October 2025.High‐resolution LiDAR data with field validation of inferred southern Ontario ice stream terrains indicate that steady‐state ice streaming is difficult to reconcile with our observations. Rather, these new observations show strong evidence of significant fluvial scouring across the area in which meltwater sheet flow overtopped the landscape.
