| This mature beech hedge borders the herbaceous garden at Anglesey Abbey (28 km NE of Royston), and being some 200 metres in length makes an impressive sight in the winter sunshine (5th January 2008 at 1144 GMT). The herbaceous garden itself is a blaze of colour in June and July but naturally is dormant at this time of the year. A statue of the Saxon god 'TIW' by J.M. Rysbrack (1694-1770) is placed at the centre of the pristine lawn to the left of the picture, but like most of the statues at Anglesey Abbey is covered during the Winter months for protection from the elements. At Royston the sunshine of the day ended at 1350 GMT, having accumulated a total of 5.0 hours by this time. | The first half of January was fairly wet in the region (but not excessively so at Royston) and streams and rivers in the catchments of the rivers Great Ouse and Nene to the N and NW of Royston were in spate for much of this time. This was the scene at Orton Staunch on the river Nene some 2 km upstream from the cathedral city of Peterborough (65 km NNW of Royston) at 1234 GMT on 16th January 2008. The normal waterfalls at this location have disappeared completely and the water is being allowed to flow straight through to ease the pressure on the upper parts of the catchment, resulting in very high water downstream from the locks. This is the last but one set of locks before the open sea. | This view of Royston from Therfield Heath has featured in these pages before but not in mid-Winter as in this photograph taken on 24th January 2008 (at 1513 GMT). The town of Royston in the middle distance is mostly hidden by trees although the tower of the 12th Century Parish Church of St. John the Baptist can be seen highlighted in the sunshine at the centre right of the picture. To the left of the photographer's vantage point the land drops away to the South Cambridgeshire Plain, whilst visible in the distance is Hyde Hill to the E and NE of the town. With low pressure centres in the Denmark Strait and to the S of Iceland, and high pressure over the Bay of Biscay, a strong WNW wind is traversing the Heath. |
