Lake Superior is almost completely frozen over this winter—a rare occurrence. This recent Moderate Resolution Imaging Spectroradiometer (MODIS) image from March 12, 2003, shows the lake’s icy blanket.
The high-resolution image provided above is 500 meters per pixel. The MODIS Rapid Response System provides this image at MODIS’ maximum spatial resolution of 250 meters.
