![]() It is far more expensive than plaster, but is nearly certain to yield superior results. This product is marketed to the law enforcement community for forensic track casting (of human foot prints and tire tracks). If you find these results unsatisfactory, you can purchase a product called Snow Print Wax. With any luck, you should have a nice cast of your track, though it is not likely to be a nice as the ones you can cast in mud. The mix may take well over an hour to cure, so you might want to leave it for a day. The spot where the plaster is poured will very likely leave an impression in the snow, and you do not want that to overlap the track. Pour it next to the track and let it flow gently into the track itself. Once the plaster is mixed, carefully pour it in the ring, but do not pour it directly in the track. Leaving snow in the plaster will cause air bubbles in the final cast. Stir the snow around until the water is really cold, but if it does not all melt, scoop it out. Use cold water when mixing it, and make it even colder by tossing in a few fists full of snow. To counteract the heat generated by the plaster, store the powdered plaster outside so that it can be cold when you mix it. Allow the water to freeze, making a much harder surface than the untreated, powdery snow. ![]() If the snow is powdery, spray water on it with a plant mister. However, tracks are a lot easier to find in the snow, and casting can be done if you are careful. Furthermore, plaster generates heat when it is mixed, and this can easily melt the snow surrounding the track. Snow is difficult to cast because it is not nearly as firm as mud. There will likely be plenty of easily identifiable kinds of tracks, and the smooth mud makes for excellent casting.Ĭasting Tracks in Snow One good way to complete this requirement is by heading to a river right after flooding has receded. If you set out for more, be sure to come back to collect your cast. Once this is done, you can set out in search of more tracks, or you can wait until the plaster sets. It should be about the same consistency as pancake batter or apple sauce. Mix water with the dry plaster and stir it until it is smooth. ![]() It sets quickly, so you will not want to mix up too much at a time. Once the ring is in place, mix just enough plaster and water to fill the ring up to 2.5 cm deep. What a pity it would be to find a huge bear or moose track and not have a large enough ring to cast it! You can also make the cast without a ring, but it is much better if you use one. Make sure the ring is larger than the track, and note that some tracks are 15 cm long or more. ![]() You can also cut one from a water bottle (for small tracks), a two-liter soda bottle, or a milk jug (the ring does not have to be round). The ring can be made from almost anything - a large tin can with the bottom cut out, a paper cup with the bottom removed, a strip of poster board 4 cm wide and taped together at the ends to form a circle, etc. When you find a suitable track, place a ring around it. It will need to be soupy to make a detailed cast. It is probably better to get the dry type so that you can mix it on site. Plaster of Paris can be bought either dry, or ready-mixed. To do this, you will need to bring dry plaster of Paris, water, a mixing container, a mixing stick (a paint stirrer will do nicely), and something to make rings out of.
