Lodge moraines: a common yet underreported end‐moraine type—a review

Boreas, EarlyView.
Lodge moraines are a distinct genetic type of end moraine formed by submarginal accretion of subglacial till; they are some of the largest end moraines in the world. Although underreported in the literature, they are of equal importance to push, dump and hummocky end moraines. End moraines are formed at glacier ice margins and show the extent of former

Ice-marginal sedimentation and processes of diamicton deposition in large proglacial lakes, Lake Erie, Ontario, Canada

, 2017
Detailed studies of coastal cliff exposures through two end moraines form the basis for a model of ice-marginal sedimentation in large ice-contact glacier-fed lakes. The input to the ice-marginal environment directly from the glacier included subglacial

Sediment Characteristics and Architecture of Triangular‐Shaped Murtoos: A Test of Murtoo Formation Hypotheses

Earth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.
Murtoos and murtooized terrains are new types of subglacial landforms found in the Fennoscandian Ice Sheet (FIS) and Cordilleran Ice Sheet (CIS) regions. LiDAR‐based morphometric analyses have revealed substantial morphometric diversity among murtoos and murtoo‐related landforms, while sedimentological excavations have documented a wide range of ...

Deep Learning Models for Mapping Surficial Geology in Selected Physiographic Regions of New York

Earth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.
Deep learning models provide a faster, less resource‐intensive approach to mapping surficial materials. Though not a replacement for traditional mapping, the models and framework developed here can enhance the speed, consistency and quality of surficial geologic mapping when trained with high‐quality data, especially in glaciated terrain.

The Mount Feather Diamicton of the Sirius Group: an accumulation of indicators of Neogene Antarctic glacial and climatic history [PDF]

, 2002
A paucity of data from the Antarctic continent has resulted in conflicting interpretations of Neogene Antarctic glacial history. Much of the debate centres on interpretations of the glacigene Sirius Group strata that crop out as discrete deposits along ...

Formation of clastic sediments in the Atl cave of the Sierra Zongolica, Veracruz Mexico, and their relationship to the soil cover

Acta Carsologica
Allochthonous cave sediments contain important paleontological and archaeological records as well as indicators of recent ecological processes. Correct interpretation of these records requires knowledge about the sediment sources and deposition processes,

Early deglaciation history of the southeastern Baffin Island shelf (Eastern Canadian Arctic Archipelago)

Journal of Quaternary Science, Volume 41, Issue 5, Page 686-701, July 2026.
ABSTRACT During the last glacial period, the Laurentide Ice Sheet (LIS) was the largest terrestrial ice sheet on Earth. Its evolution since the Last Glacial Maximum profoundly influenced Earth's geodynamics and surface processes. Investigating the past dynamics of the LIS provides critical insights into how contemporary ice sheets may respond to ...

Retrogressive Thaw Slump Morphology and Dynamics in Saline Permafrost in Northeast Greenland

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract Saline permafrost occupies a significant portion of permafrost in the Northern Hemisphere and extends several kilometers inland from the present Arctic coastline. However, its thermal conditions, mechanical degradation and geomorphological impacts are poorly understood.

Dynamic Deglacial Evolution of Interior Seaways and Ice Streams in the Weddell Sea Embayment

Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract Improving our understanding of Antarctic glacial dynamics is essential for accurately predicting ice sheet behavior and its contribution to global sea level rise under future climate scenarios. The Weddell Sea Embayment, which channels ice from East Antarctica, West Antarctica, and the Antarctic Peninsula into the Filchner‐Ronne Ice Shelf, is ...

Micromorphology of Last Glacial Maximum Grounding line sediments around the Antarctic Peninsula [PDF]

, 2012
Sediments recovered from seven Last Glacial Maximum grounding lines sites, around the Antarctic Peninsula, were analyzed using micromorphology. This is the first evidence that grounding line sediments from around the Antarctic Peninsula have complex ...
