Geography field trip - Snowdonia

Posted 1st May 2026

Year 8 visited Cwm Idwal on a geography field trip to investigate whether the landscape had been shaped by glaciers. During the trip, students looked for key evidence of glaciation, such as the steep, bowl-shaped valley (a corrie), sharp ridges, and scattered rocks known as erratics.

They also observed smooth rock surfaces that may have been worn down by moving ice. By recording their observations and comparing them to what they had learned in class, the group gathered evidence to decide whether Cwm Idwal is a glaciated landscape.
