This grassland site in the valley of a tributary of the River Wissey has a number of pingos, damp and water filled depressions formed by the melting of ice at the end of the last glaciation. It also has a lake called Thompson Water which, together with its surrounding reedswamp, is important for breeding birds.[7]

The site is open to the public.
