The Harding Icefield and its outflowing glaciers cover 700 Square miles of Alaska’s Kenai Mountains in glacier ice. It is over 23,000 years old. It’s a feature of the Kenai Fjords National Park and I climbed up to see it via Exit Glacier Trial. It was one of the most beautiful walks of my life seeing the ice capping the earth and the rock (called Nunatak) emerging through it.
