I like the idea of the snowflake cut out design as well. Shaped coins always look nice in my opinion. Maybe the words that radiate from the center out to make the flakes, could be the words you all described for a coin, like snowshoe, camping, hiking, pine tree, etc. in tiny words to make the imprint of the flake design.
Or, you could have a spinning snowshoe pair in the middle of the flake,( but I suppose spinners would be expensive), or a small cut out snow shoe attached to the flake with an o-ring, that was imprinted with the words ten year anniverary. That would be different.
