As you tour this gallery, you will see several visible and infrared views of the geothermal features found in Yellowstone National Park. The temperature scale (Fahrenheit) below the infrared images will tell you which colors represent warmer or cooler temperatures. The temperatures on the scale are a measure of the heat or thermal radiation detected by our infrared camera, which was quite a distance away from the geothermal heat sources. Although the temperatures shown are not the actual temperatures of the geothermal features (which are much warmer!), they do show the relative distribution of heat. |
