Our shoutout for the top social post of the day on Banff Lake Louise goes to @chessnyc on Instagram. From @chessnyc: Banff National Park is home to stunningly blue lakes, including Lake Moraine, Lake Louise, and Emerald Lake. Their unique turquoise hue comes from "rock flour" created by glacial activity, giving the waters their glowing appearance. #BanffNationalPark #vctnday
