Ice Covers the Great Lakes
This page contains archived content and is no longer being updated. At the time of publication, it represented the best available science. However, more recent observations and studies may have rendered some content obsolete.
These Moderate Resolution Imaging Spectroradiometer (MODIS) images show the ice in Lake Superior on February 16, 2003, and again on March 7, 2003. It is very rare for Lake Superior to freeze over completely due to its large size and great depth, both of which inhibit freezing.
The high-resolution image provided above is 1 kilometer per pixel. The MODIS Rapid Response System provides these images at MODIS? maximum spatial resolution of 250 meters. (Links below.)
