Lenton, Keisby and Osgodby is a civil parish in South Kesteven, Lincolnshire, England.

[2] It is located along the river and in the valleys of the East Glen at its headwaters near Ingoldsby, where several minor streams join.

[3][4] 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.

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 streambeds of the Glen have their own associated alluvial linings of Sand And Gravel, Silt and Clay.
