Stiperstones

The Stiperstones (Welsh: Carneddau Teon) is a distinctive hill in Shropshire, England. The quartzite rock of the ridge formed some 480 million years ago. During the last Ice Age Stiperstones lay on the eastern margin of the Welsh ice sheet. The hill itself was not glaciated though glaciers occupied surrounding valleys and it was subject to intense freezing and thawing which shattered the quartzite into a mass of jumbled scree surrounding several residual rocky tors. At 536 metres (1,759 ft) above sea level it is the second-highest hill in the county, surpassed only by Brown Clee Hill (540 metres (1,772 ft)). Stiperstones' 8-kilometre (5 mi) summit ridge is crowned by several jagged outcrops of rock, which may be seen silhouetted against the sky.
