NASA’s Terra satellite captured the spring thaw underway in the Great Lakes of North America. While thaw has begun, a snow line still persists through Wisconsin, Michigan, and Ontario. As the snow melts, the line will recede and meltwater will help replenish lake levels. In this image just 20% of the total lake area was still covered with ice.

The Great Lakes are a series of interconnected freshwater lakes primarily in the upper mid-east region of North America, on the Canada–United States border, which connect to the Atlantic Ocean through the Saint Lawrence River. The Great Lakes have a humid continental climate, and winter becomes severe without which halts over-the-water transportation. On March 25, the Soo Locks reopened for the 2019 shipping season.

The local scenery on the ground is as follows.
