Seasonal places

This loch only appears in winter, on Granish Moor, so I call it the Winter Loch.

Does anyone know if it has a 'proper' name? Or does anyone have their own names for it?

It's the highest I've seen it in a few years, lapping up to the dead Mini.

​How many other places do you know locally that are seasonal, only appearing in winter or summer? Or spring or autumn for that matter...
