Every year monarch butterflies begin a journey north from their overwintering grounds in Mexican forests. The epic migration spans generations and the better part of a continent. And it touches the lives of countless scientists and citizens. Check out our new Google Earth tour, produced by Atlantic Public Media, in partnership with the Encyclopedia of Life and a Google Outreach Developer Grant.
Watch the tour with Google Earth by downloading the KMZ file, or on YouTube:
