Lake. Sognsvann, Oslo Norway.
I lived and worked for ten days and nights on a frozen lake, using a traditional ice saw to cut out a free-floating raft from the lakes ice.
The journey would end when the raft broke free. See video here..
In the months leading up to Journey, I camped with some immigrant job seekers in the forest near the lake. 

We attempted to build a winter cabin to survive the winter, only to abandon the build after discovery by local authorities. See slide show here.
