Lake District - Glaciated Landscape

7,347 views

Published on

This presentation looks at the geology of the Lake District and the impact of glaciation on the landscape.
The existence of over 50 well-developed corries is unequivocal evidence that parts of the landscape were affected by glacial erosion during the Quaternary.

  • You're spot on Peter. Thanks for the comment. The actual cross section is generally parabolic in shape. Mind you, it was the turn of the millennium before the kids started getting marks from our exam board for saying so. The kids will also work out the role of valley fills as soon as they have to draw a few sections. Geography is a conversation, a life-long conversation. Thanks for your contribution. Much appreciated.
    I'll change the wording to something a bit more accurate.

  • Nice presentation, some really good slides in here... and thanks for the reference! Slide 35 says '...characteristic u-shape with steep, straight sides, and a flat bottom.' Er... is that really 'u-shaped', then? Glacial erosion does produce u-shaped valleys, but the bottoms can subsequently be flattened out by deposition (eg infilling of glacial lake). Straight sides are more characteristic of big meltwater channels (flat-bottomed gutter shape), but near-straight sides could occur in glacial valleys if, for example, the original eroded sides are mantled in scree.
