Labyrinth Rosette Challenge

I have postponed forming the 6 petals of the Rosette. Now, I am faced with the challenge of how to shape and build the petals. Of course, I need some new snow to build them as it would be very difficult, not impossible, to carry hundreds of pounds of snow to center. The six petals represent: Minerals, Plants, Animals, Humans, Angels and the Great Unknown. When reaching center, we can contemplate, pray, meditate or rest in each petal.
