English: River Kennet between Avebury and Silbury Hill The muddy bridleway from Avebury to the Silbury Hill car park runs along the eastern bank of the River Kennet, which is a large stream at this point. The shady side of Silbury Hill can be seen across the water meadow and the West Kennett long barrow is visible as a long dark shadow on the ridge in the distance, towards the left of the photo. The Ordnance Survey map labels the river as ending in a single "t" (Kennet) whereas the surrounding placenames that incorporate the name end in a double "t" (West Kennett).
