<<Back to this week's update   How Far from Mexico? Look how far the migration has advanced northward and eastward! Remember: the coordinates of the overwintering sites in Mexico are 20 North and 100 West: Northern-most Monarch at 47 North! That's 27 degrees north of the latitude of the overwintering sites in Mexico. Eastern-most Monarch at 63 West! That's 37 degrees east of the longitude of the overwintering sites in Mexico.
