Introduction | Case study 1 | Case study 2 | Summary What is glacial surging? Glacial surging refers to the sudden movement of ice over a relatively short period of time resulting in rapid glacier advance that is different from the usual glacier activity 1. Examples of surging can be found across the world, e.g. […]

Introduction | Mass Movements | Rockfall and Avalanches | Ice and snow avalanches | Landslide and debris flow | Case Study What are glacial hazards? Generally, there are two types of hazards found in glacial environments that can impact humans. First, we have direct hazards such as avalanches and rockfalls. Second, we have indirect hazards

By Alex Hyde The sub-tropical glaciers of Bhutan Bhutan is a small mountainous nation located in the Eastern Himalaya, with a population of around 727 000 people (Figure 1). The country has a sub-tropical climate in its south, where it borders lowland plains, and a Himalayan subalpine climate to the north where it meets the

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

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

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

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

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
