The Long Winter, 1880-81, Minnesota. "There were no winter thaws and on February 2, 1881, a second massive blizzard struck that lasted for nine days. In the towns the streets were filled with solid drifts to the tops of the buildings and tunneling was needed to secure passage about town. Homes and barns were completely covered, compelling farmers to tunnel to reach and feed their stock."

Each year, the final generation of Monarchs, which emerges in late summer and early fall, has a job: to migrate to overwintering grounds, in central Mex for east Monarchs or in Cali for western Mon. Here they survive the long winter until conditions in the US allow them to return to reproduce. adults can live up to 8-9 months.
