Snow and Ash Above Katmai

Snow and Ash Above Katmai

A plume of volcanic ash hangs over the Gulf of Alaska in this natural-color image. The plume is not the product of an active volcano; it is re-suspended ash from the 1912 eruption of Novarupta, according to the Alaska Volcano Observatory. High winds previously stirred up ash in the area in October 2015.

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image on December 2, 2016.
