Well the votes have been counted and verified (by an independent adjudicator) and it seems there was an outright winner of the "most beautiful volcano" contest...
and the winner is... Kilauea, Hawaii
Just a little bit of extra info about Kilauea for those who are interested:
Kilauea is the youngest and southeastern volcano of Hawaii's Big Island. Kilauea is the home of Pele the Hawaiian volcano goddess. It is said that when she is angry the volcano erupts. Well this volcano has been erupting continously since 1983, so it seems Pele is rather cross about something. For more information check out the USGS website for some more great images and history of the volcano.
Thanks to all who voted!
