About the Eastern Yar
The River Yar on the Isle of Wight, England, rises in a chalk coomb in St. Catherine's Down near Niton, close to the southern tip of the island. It flows across the Lower Cretaceous rocks of the eastern side of the island, through the gap in the central Upper Cretaceous chalk ridge of the Island at Yarbridge, then across the now drained Brading Haven to Bembridge Harbour in the northeast. It is the longest river on the Isle of Wight.
