Volcano in St. Lucia

We visited St. Lucia as a part of our cruise trip to the Carribean on 30th January 2008. One of the famous places there to visit is the live volcano near the town of Soufriere (French for Sulfur). From what we learn, that is the world's only drive-in volcano. The white smoke in the picture is actually water steam. The yellow-greenish stuff is sulfur.

As of today, there is no way to record smell. Otherwise, it would be very nice if you see this photo and at the same time smell what we smelled there. We can describe the smell there as rotten eggs. The volcano tour guide told us that the smell is good for our sinuses. We could not tell since we were there just half an hour.
