One of many on Thompson Common, wide range of dragonflies and damselflies around this small pond. Pingos are formed when an ice lens builds in permafrost conditions (15000 years ago here). This pushes up a small hillock and the soil (saturated by snow melt above impermeable ice) slumps down the side so thins out on the hillock. When the ice lens melts, a depression is left. In this area these depressions have been preserved to create a natural wetland.
