River Teme - the wanderer.

Taken from the bridge at Monaughty Poeth, at a time of low water.
Look carefully at the map here. Both banks are in Radnorshire, and the Radnorshire-Shropshire border wanders about, not matching the river as expected. The reason? The border was fixed in the 16th century,when the Marcher Lords were abolished and Wales was "united" with England. Since then the river has gone walkabout - meanders forming and being abandoned. A landscape can change quite quickly.
