With your eyes still closed, describe the object to the other person. You will have a vivid image in your mind which you will not soon forget. A trail of tracks often tells a story of the habits of an animal in the winter. A tiny mouse scampers about on the snow surface looking for seeds that are blown by the winter wind then darts back to its tunnel. A daring rabbit leaves the protection of a thicket and gets grabbed by a hunting owl, the rabbit tracks disappear from th snow and an imprint is left by the wing brushing the surface of the snow.
Deep tracks indicate a large heavy animal.
Try leaving your own fake animal tracks that tell a story. Look for other signs such as nibbled twigs and dug holes. Try melting a known volume of snow in a pot to see how much water is actually in snow. Compare its melted volume with the snow volume. Measure and compare the temperatures of the air and snow, the snow at the surface, snow down at 25 cm and snow at 100cm.
