Rock Types at Great Heights (2012x311)

:

Tests how close we can get to geological formations and geographic process while hanging from a cliff face. Geologist and keen climber Dr Tom Challands challenges three pairs of young people each to climb a different rock face and see just what can be revealed from this unique vantage point, on the rock face rather than observing from the ground. The climbs in Snowdonia and the Peak District are not only technically demanding but throw up different field study challenges for the teams to solve. The programme looks at volcanic activity, glaciation, how human activity shapes a landscape and formations created as a result of massive river deltas.
