On October 1, 2019, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this false-color image of snow across the U.S. state of Montana and the Canadian provinces of Alberta and Sasketchewan. The image combines natural and infrared wavelengths in order to distinguish snow and ice (cyan) from clouds (white). Following a snow storm on September 29-30, some areas in the region were blanketed with as much as two feet of snow—just one week after the start of astronomical autumn.
