Introduction | Types of glacial lakes | Moraine-dammed | Ice-dammed | Bedrock-dammed | Supraglacial | Subglacial | Summary What are glacial lakes and where are they found? During the last few decades, accelerated ice mass loss and glacial retreat has resulted not only the expansion of existing glacial lakes but also the formation of new […]

By Dr Richard Waller, Keele University, and Dr Bethan Davies, Royal Holloway University of London During the Younger Dryas, the Lake District was covered by plateau icefields and cirque glaciers[1]. The image below shows the larger plateau icefields (green) and the smaller cirque glaciers (red) in the Lake District and Snowdonia. You can explore all

The Loch Lomond Stadial in Britain Between 12,900 and 11,700 years ago, gradual warming of Britain’s climate was interrupted by a sudden period of renewed cooling. During this period, known as the Loch Lomond or Younger Dryas Stadial, glaciers regrew in many areas of upland Britain. Evidence of these glaciers is preserved in a range

This article on glacial geomorphological mapping was written by Dr Benjamin Chandler from Stockholm University. Why do we map glacial landforms? Geomorphological mapping is an important method used by glacial geologists to study the behaviour of past glaciers and ice sheets1. By mapping the distribution of glacial landforms and investigating the spatial relationships between different

Ridges, mounds and hummocks formed at the margin of glaciers are generally termed moraines. The study of moraines is particularly useful as it can shed light on the physical processes occurring at both active and former ice margins1,2 and because moraines are markers of former glacier extent, so can be used to track glacier change
Moraines are distinct ridges or mounds of debris that are laid down directly by a glacier or pushed up by it1. The term moraine is used to describe a wide variety of landforms created by the dumping, pushing, and squeezing of loose rock material, as well as the melting of glacial ice. In terms of
This section of the website includes many examples of landforms created underneath and around the margins of glaciers. These depositional landforms typically form in two domains: subglacial landforms and ice-marginal landforms. Subglacial landforms include: A continuum of lineated bedforms, ranging from small scale (flutes), through to intermediate scale (10s of metres; Drumlins), through to large
