Snow flakes reflect light

Hi, it may seem strange but snow is actually very bright and its a good idea to wear sunglasses when its sunny and snowy. Thats because the sunlight is reflected by all the snow flake crystals.
In places like Antartica, where Ed the Bear visited recently, you can suffer badly from the bright sun reflecting of the snow. They call it snow blindness but it doesn't make you permenantly blind.
I took this picture near my house at night (without a flash) and you can see all teh way up the trackbecause the snow reflects the moon light and the street lights.
This is a picture I took of foxes a few weeks ago - its all black and no sighn of the foxes. The snow makes a real difference to seeing at night.
