This grassland site, located in the valley of a tributary of the River Wissey, contains a number of ponds left by melted pingos: damp, water-filled depressions formed by the melting of ice within these geological formations at the end of the last glaciation. It also features a lake called Thompson Water, which, along with its surrounding reed swamp, is important for breeding birds.[7]
The site is open to the public.
