North Shropshire is full of interesting geomorphological features produced largly through the effects of various iceages over the last few thousand years.

The meres are what are known as 'Kettle Holes'.  These formed when detached blocks of ice were left behind by a retreating glacier. The lump of ice forms a depression surrounded by drift deposited by the melting glacier.  Eventually this block to will melt filling the depression with water.

The material left by the retreating glaciers also make features. These are eskers and morrains and form linear features through an otherwise flat landscape.
