Answer:
That may explain the origin of Groundhog Day in general, but it offers few clues on how groundhogs got involved. For that, we can thank 19th-century German immigrants and a creative city editor at the Punxsutawney Spirit newspaper.
Germans who settled in Pennsylvania in the 1800s brought many customs from home, including an old practice of predicting the end of winter based on bears' and badgers' hibernation habits. Some Germans may have switched to groundhogs when they arrived in America, but the new tradition didn't really take off until the late 1880s, when a group of local groundhog hunters caught the attention of Punxsutawney Spirit city editor Clymer H. Freas.
Freas reported on the men's groundhog hunts and barbecues, touting them as members of "the Punxsutawney Groundhog Club." He became so enthralled by local groundhog folklore that he went on to promote Punxsutawney as home to a weather-predicting groundhog, a story he then continued to repeat and embellish year after year. Other newspapers began reporting it, too, and Punxsutawney soon became ground zero for groundhog meteorology, as well as the hometown of world-renowned forecaster "Punxsutawney Phil."
