today's wind gap, is not lower than (Tongham Pool) and of very low gradient. This transported distinctive gravels containing chert, to deposit them north of the gap in the chalky ridge at Farnham. The source rocks of the gravels prove the former extent of the river. Great erosion has occurred in the Wey down to Tilford, along the sinuous, multiple-anabranch Waverley Abbey stretch, through, what Blyth notes as, the "soft strata", of that landscape. Wey South The Wey South branch stems from two main westward brooks, one now followed by the Portsmouth Direct Line, the other – with longer source brooks – following the Surrey/Sussex boundary, which combine at a point, heading west, where the line first comes as close as 97 metres to the boundary – in the east end of a park, next to one of its three river footbridges. These brooks are fed by six main streams. The farthest are the southern streams. These drain parallel, north, narrow vales between the northerly "fingers" or "ribs" of: Blackdown, the third-highest hill in Southeastern England Ridge Hill Fridays Hill Marley Heights (formerly Moseshill), called Marley Common The northern streams drain fingers of a single east–west ridge of Greensand, their common names, again from east to west, are: Wey Down (High Lane Estate) Inval(l) Stoatley Rise Brownscombe Of varying size, these are long, sandy hills south-east of the upper tip of the Devil's Punch Bowl: Gibbet Hill, Hindhead. One of the northern streams adjoins strips of woodland named Weydown Common and Weycombe. The south sources are specifically: a wood-surrounded neighbourhood, Kingsley Green (formerly Marsh) in Fernhurst; Chase Farm marking the furthest point south in Surrey; and upper fishponds at Wades Marsh marking the Fernhurst/Lurgashall boundary (both in West Sussex), next to the summit of Ridge Hill (which is the furthest source). The Wey drains and passes Haslemere's western suburbs then Liphook, Bramshott (including Passfield), Standford and Lindford, and the large parish of Frensham. It combines with the north branch at Tilford, in which parish all three flows have large meanders. Notable tributaries of the south branch are Cooper's Stream and the River Slea. Combined river From Tilford the river runs through Elstead, Eashing, Godalming, Peasmarsh/Shalford, Guildford, Send, Old Woking, Pyrford, Byfleet, New Haw and forms the historically much more meandering border between Addlestone/Weybridge, today doing so most accurately between Hamm Court and Whittet's Ait respectively. From Godalming the river is
