      On December 12, 2022, the Moderate Resolution Imaging Spectroradiometer   
      (MODIS) on board NASA’s Terra satellite acquired a true-color image of   
      snow surrounding Manicouagan Reservoir in southeastern Quebec, Canada.   
      
      This strikingly circular lake is the most important reservoir of the   
      Manicouagan Hydroelectric Complex. The reservoir itself was created in   
      the 1960s when the Daniel-Johnson dam was completed, flooding two   
      arched lakes that were previously present. The rising floodwaters also   
      created a new island on a high plateau between the lakes.   
      
      While the reservoir is relatively new, it has been built on a truly   
      ancient foundation—one of the Earth’s largest and oldest impact   
      craters. Manicouagan Crater was formed 214 million years ago, near the   
      end of the Triassic Period, when an asteroid 5 kilometers (3 miles)   
      wide struck what is now Canada. The asteroid's impact not only created   
      a rounded impact crater, but the massive power of the impact shattered   
      rock and debris, causing it to uplift in the center of the crater. This   
      uplifted area is now the Ile Rene-Levasseur. The highest point on the   
      island, Mount Babel, rises about 1,970 feet (600 meters) above the lake   
      level on its northern end.
