These photos from the Glacier Photograph Collection show a dramatic loss of glacial ice over several decades that has radically changed the landscape. They are an important historical record for researchers studying the response of glaciers to climate change.
More than 15,000 photographs of glaciers in the Rocky Mountains, Alaska, Pacific Northwest, and the Rocky Mountains are in the database which contains photos dating back to the mid-1800s.
In the United States, glaciers cover over 75,000 square kilometres, with most of the glaciers located in Alaska, according to the National Snow & Ice Data Center.
Within the National Snow & Ice Data Center collection are a smaller group of glacier photos from Europe, South America, the Himalayas, and Antarctica.
