The Greensand Ridge, capped by the resistant sands and sandstones of the Hythe Beds, reinforced by bands of chert, rises steeply as a series of high, wooded escarpments between Gibbet Hill, Hindhead (272m), north of Haslemere, and the ridge's highest point, Leith Hill (294m).
In many places along the escarpment of the Greensand Ridge erosion by wind and rain, landslips on the steep scarp face, and solifluction in glacial times have further combined to create steep-side coombes, and low hillocks below the scarp.
