Ghost Hills

Did they know that they would become this?

Breckland, after the ice sheets.

The most formidable glacial advance in the entire Pleistocene is named ‘Anglian’. The East Anglian peninsula was swallowed by it – this meadow once looked like Greenland. As the climate warmed, standing blocks of ‘dead’ ice were left behind, eventually to be topped with soil and grass like surviving examples in polar regions. The Inuit word pingo is used to describe such hillocks with a heart of ice. They would have stood tall over the flat Breckland landscape, but they pressed into the soil like a knee. 

But they melted, in time. Now, their legacy is ponds. The ghosts of lost hills, water-filled depressions carved by ancient glacial games.

Breckland is rich in pingo ponds, also known as kettle ponds. It is also very rich in dragonflies, rare beetles, great crested newts and other species that appreciate wet habitats. Northern clade pool frogs, the UK’s rarest amphibian, made its last stand in the pingo ponds, and has recently been reintroduced.

Away from the water, other species exploit the meadows. Six spot burnet moths are hard to overlook.

I heard many birds calling, but didn’t get any good photos of them today. Here’s a couple from another Breckland visit a couple of weeks back: goldfinch…

And a juvenile blue tit.

Two very common British species, but the Brecks can do far better; it has stone curlew, turtle dove and many other specialities. In total, nearly 13,000 different species of wild things have been identified, and many have comfortably rubbed shoulders with farming for millennia. Poppies on the edge of an arable field are a reminder of that.

And all of it, from the soil to the sky, is a reminder of the ice.
