On 20 November at the Jämtland Sweden, the Jonas Landmark and Karin Brooks made skating on Lake Blanktjärn, along with their two dogs, Trisa and Velma. In winter, the Lake is frozen, but the thin layer of ice 10 to 15 cm are translucent. The surface can be seen clear the bottom of the Lake, and observe the fish at about 10 meters depth. A very beautiful experience.
