The main centres of population are in the River Blackwater valley between Farnham and Camberley, and in the River Wey valley at Guildford and Woking. The character of the district is strongly influenced by the underlying geology. In the north, dominantly sandy deposits of Tertiary age give rise to extensive heathland, large tracts of which are used by the Ministry of Defence. Trending east–west across the middle of the district is a narrow belt of relatively steeply dipping Chalk that between Farnham and Guildford forms a prominent ridge known as the Hog's Back. It is the surface expression of a deep-seated geological structure that separates the concealed London Platform of Palaeozoic rocks in the north from a deep basin of Mesozoic strata in the south. The exposed strata of this Weald Basin are variable in lithology and hardness, giving rise to attractive hilly countryside around Godalming, underlain mostly by the Lower Greensand that is important locally as an aquifer.
