If you are in a snow-covered area the best thing to do would be to dig down to the ground and make your fire there. The snow walls would add more protection to your fire from the wind. If the layers of snow are too thick, you will have to build a platform for your fire out of logs. Use green logs to create a dry base for your fire. That means choosing logs that are wet (contain moisture) and are not dried out (seasoned). Lay several green logs side by side on top of the snow. Create a second layer of logs in the opposite direction to the one below it. You can create a third layer as well if needed. You now have a base to make your fire on.
