The following images are reconstructions of how the Black Mountains and surrounding areas may have appeared around 20,000 years ago at the height of the Devensian Glaciation. The first view is looking northwards, followed by eastward, then southern and finally a westward view. The extent to which ice sheets extend can only be detemined from glacial deposits left behind along with erosion features characteristic of ice. There is the added complication of differentiating between different glacial events. Many have occurred over the past 2.6 million years (the Devensian was the last but by no means the most severe), whilst the Earth has been in ‘Icehouse’ conditions. A situation the planet may now be emerging from at a very rapid dangerous rate.
