Ellipsoidal Basins

Posted on 27/05/2021 / by Laura Boyall / tagged case-study, erosion, Laurentide, Post-16

Ellipsoidal Basins is a geographical term used to describe deep, elongated lakes, formed by subglacial activity beneath past ice sheets [1]. Examples of these basins include the Great Lakes and Finger Lakes of North America [1,2]. These basins were formed either where the ice was topographically constrained (Finger Lakes), had vulnerable, softer, geology (the Great

Alpine icefield landsystem of upland Britain

Posted on 05/10/2020 / by Bethan Davies / tagged case-study, cirque, Post-16, Younger Dryas

This article was written by Dr Hannah Bickerdike. 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

The Younger Dryas Glacial Map

Posted on 14/08/2020 / by Bethan Davies / tagged case-study, Post-16, resource, Younger Dryas

Welcome to the Younger Dryas Glacial Map! Here, you can explore the glaciation of the UK during the Younger Dryas glaciation. In the UK, this period is also called the “Loch Lomond Stadial”. At this time (12,900 to 11,700 years ago), there was a period of abrupt cooling. Glaciers began to grow again in much

This page highlights some of the excellent teaching resources available for exploring glacier mass balance. For more ideas, see the Resources for Teachers page. Case study: USGS Benchmark Glaciers The USGS has an excellent resource on the mass balance of Lemon Creek Glacier, a World Reference Glacier, and the other USGS Benchmark Glaciers. This has

Introduction to the Glaciation of Britain

Posted on 09/07/2020 / by Bethan Davies / tagged case-study, Post-16, UK

In this section, we discuss the evidence for the last British-Irish Ice Sheet (BIIS). Throughout the Quaternary (the last 2.6 million years), there have been many ice sheets in Britain. The ice sheet grows during cold periods (stadials) and recedes in warm periods (interstadials) like the one we live in today. The last BIIS began

Glacial erratics

Posted on 25/03/2020 / by Andy Emery / tagged case-study, erratics, LGM, Post-16, sedimentology, UK

What is a glacial erratic? Glacial erratics, often simply called erratics, or erratic boulders, are rocks that have been transported by ice and deposited elsewhere. The type of rock (lithology) that the glacial erratic is made from is different to the lithology of the bedrock where the erratic is deposited. For example, an erratic could

Cirque glaciation landsystem of upland Britain

Posted on 07/01/2020 / by Jacob Bendle / tagged case-study, cirque, Post-16, UK, Younger Dryas

The Loch Lomond Stadial in Britain Between around 13 and 11 thousand years ago, the climate in Britain, as well as across much of Northern Europe, cooled abruptly1. This short-lived cold period temporarily reversed the general pattern of warming that drove the retreat of ice sheets after the Last Glacial Maximum, causing glaciers to readvance
