Macro erosional landforms | Parabolic Valleys | Hanging Valleys | Fjords | Aretes What are macroscale erosional landforms? Macroscale erosional landforms are larger than 1 km in dimension and often contain smaller landforms (micro- and mesoscale) 1. Macroscale erosional landforms, such as Parabolic Valleys, Arêtes and Pyramidal Peaks (see Figure 1) are without a doubt […]

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 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

Glacial cirques, known locally as corries or coires (Scotland) and cwms (Wales), are large-scale erosional features common to many mountainous regions1,2. Classic cirques take the form of armchair-shaped hollows (see image below), with a steep headwall (which often culminates in a sharp ridge, or arête) and a gently-sloping or overdeepened valley floor (see diagram below).
