What body of water borders Michigan to the west?

Michigan is bordered to the west by Lake Michigan, which is one of the five Great Lakes of North America. This large freshwater lake is exclusive to the United States and is situated entirely within the country, making it a significant geographical feature for several states, including Michigan. Lake Michigan forms part of the boundary that separates Michigan's Lower Peninsula from the state of Wisconsin, reinforcing its role in the region's geography, economics, and recreation.

In addition to being a critical waterway, Lake Michigan affects climate and environmental conditions in the surrounding areas, contributing to the natural beauty and ecological diversity of Michigan's western shoreline. This includes beautiful sandy beaches, unique ecosystems, and opportunities for various outdoor activities, making it an integral part of Michigan’s landscape.
