Arctic Mirages

    These are two panoramas of the hills in the Tanana Valley, North of the Alaska Range (in the background) during strong temperature inversions over Fairbanks. The appearance of the hills is super-distorted, due to the optical effects of the temperature inversion. Mount Deborah, the highest Alaska Range peak visible in these pictures, is toward the right in each picture (use the bottom slider bar to pan both images). Compare the hills in front of Mt. Deborah in each. This type of mirage is called a Fata Morgana and is not uncommon in the Arctic. To find out more about mirages, click here.
