The 10 cm thick ice is clear enough to see the bottom of the lake and fishes swimming around."This whole skating season's been incredible. I've been out for nine days in a row. We went through 11 lakes and rivers one day. We only needed to walk 1.2 km of the stretch of four mil, the rest went to go on fine ice.
