The International Space Station may at first seem unrelated to Earth’s cryosphere—but it’s not.

Take a look here at majestic views of the US National Park system captured by NASA astronaut Jeff Williams. His images depict glacier-rich landscapes such as Alaska’s Glacier Bay National Park and Denali National Park, Grand Teton National Park in Wyoming, and Washington’s Olympic National Park, among many others.
