This year, Canada celebrates the 150th birthday of its independence and cultural heritage, which reaches a climax at the end of June. Earlier in the same month, on June 5, Canada proudly hosts World Environment Day, proclaimed by United Nations Environment (UNEP) as the day our planet celebrates our love of and reliance on nature. To this occasion, and following our visit to Great Slave Lake in January, PROBA-V puts its spotlight once more to Canada’s beautiful nature and lakes with a picture of Lake Claire (west) and a partially snow-covered Lake Athabasca (east). Lake Claire is part of Wood Buffalo national park, that is protected as world heritage and recognized as the world’s largest Dark-Sky preserve against light pollution. To the southwest of Lake Claire, we find the world’s largest beaver dam (850 m long), that was initially discovered by satellite.
