The highest land at the east and west is a small plateau of a Kellaways Sandstone laid down approximately 161 to 165 million years ago in the Jurassic Period. These lie some 80m above sea level. The East Glen valleys cut through this to a slightly older Blisworth Clay Mudstone layer, exposing thin layers on Kellaways clay and Cornbrash limestone on the way. The whole is overlaid with Quaternary glacial till from the recent Pleistocene. The lowest point in the parish is probably about 45m at the Ford in Osgodby, across the east Glen. The streambeds of the Glen have their own associated alluvial linings of Sand And Gravel, Silt and Clay. which became a
Cold War missile base. The parish is crossed by the route of the
Roman road of
King street. There are no major roads in the parish, and no railways. ==Constituent settlements==
