I have been watching for animal paw prints to start crossing the ice. It is amazing to me, though, how quickly the ice is solid enough to hold small mammals. It is hard to tell wild from domestic along the path in winter – dog prints trample everywhere, regardless of the 2 meter leash law in effect. But I’m pretty sure only wild creatures would hazard the ice and make it across.
You can see where a single animal has crossed. In other parts of the river, there appear to be gathering points with many tracks leading to one place and then branching off in a variety of other directions.
