National Geographic Travelさんのインスタグラム写真 - (National Geographic TravelInstagram)「Photo by @tobyharriman / The Matanuska Glacier is one of my favorite places in Alaska. This year I finally visited in winter! The ice features you’re able to explore with the help of a skilled guide are beyond incredible and would be unsafe in summer. I hope this beautiful glacier will be accessible for generations to come, but glaciologists say that Matanuska has been steadily shrinking approximately 32 feet (10 meters) annually since the 1960s because of climate change.
