Montserrat

As we sailed up the leeward side of Montserrat we could see the volcano, its huge ash flows, and the ruins of Plymouth. There's a maritime exclusion zone off the south half of the island that requires that we keep 2 miles off. Of course, our curiosity had us around a mile off and for our trouble we got the boat covered in a thin coating of fine ash.
After clearing in we rented a taxi and took a tour of the island. This took us into the Exclusion Zone where we could see abandoned homes and layers of ash feet thick. From a hill we saw a panorama of the volcano, some of its ash flows and a better view of what's left of Plymouth. We also visited the Montserrat Volcano Observatory where they are studying the volcano to help better predict eruptions here and elsewhere.
We stayed in Rendevous Bay (the only anchorage available) for about a week and even did a dive. The day before we planned to leave there was a 3 hour volcano 'event' (as termed by the Montserrat Volcano Observatory). A boat left that morning and sailed down the leeward side of the island. The returned a few hours later with their boat thick with volcanic ash. They spent the rest of the day sluicing the ash off and it ran thickly down their sides!
Needless to say, the next day both of us sailed around the north end of Montserrat to go down the windward side on our way back to Guadeloupe!
