During ice ages landscapes are sculpted by the power of advancing glaciers. From rock scratches, to changing mountains and the formation of corries, cirques and aretes, through to the formation of valleys and fjords, the effects of past glaciations are evident across the northern hemisphere landscape. Perhaps not so familiar, drumlin fields are also vestiges of the erosive power of ancient ice she ...[Read More]

A by-product of eruptions of tall, steep-sided stratovolcanoes, lahars, are often triggered by the quick melting of snow caps and glaciers atop high volcanic peaks. The history of the Ibañes River and its valley, in southern Chile, are dominated by their proximity ...[Read More]
