LANSING (AP) – A bill has been signed into law that aims to protect three areas of state-owned land in the northeastern Lower Peninsula of Michigan from artificial light pollution.

Gov. Rick Snyder signed the bill Tuesday. The areas now designed as dark sky preserves are Rockport State Recreation Area in Presque Isle and Alpena counties, Negwegon State Park in Alpena and Alcona counties, and Thompson’s Harbor State Park in Presque Isle County.
