Succession is the aging of a lake. A lake can start out from a receding glacier, like Lake Lacawac, in a crater left by an asteroid, in a depression left from a volcano, or many other processes. As a lake ages it will go through three stages, oligotrophic, mesotrophic, and eutrophic. Find the QR codes ahead to learn more about these stages. Eventually over thousands of years a lake will fill in will sediment and organic material becoming a bog or wetland.
