The Old Glaciers of Switzerland and North Wales

Glaciers are magnificent natural wonders that have shaped the landscapes of many regions around the world. In this article, we will delve into the old glaciers of Switzerland and North Wales, exploring their formation, their impact on the environment, and their significance in the history of these regions.

Formation of Glaciers

Glaciers are formed over thousands of years as layers of snow accumulate and compress into ice. The weight of the ice causes it to flow slowly downhill, carving out valleys and shaping the land. The glaciers in Switzerland and North Wales are remnants of the last Ice Age, which occurred around 10,000 years ago.
