Hi!
I am a science writer for the Midland Daily News in Midland, MI. I've been
watching the developments on Montserrat with great interest. I was there 10
years ago and had a chance to climb around in the old volcano where fumaroles
were still active. I have a shot of several of my friends climbing
around on what looks to be an old, rotten lava dome. I want to identify
the type of lava (it's yellow-white). Would it be dacite, rhyolite or
andesite? In my article, I'll be talking about plate tectonics,
subduction and island arcs.
By the way, I take it you are in North Dakota. What is Volcano World doing
there, in the vast, stable expanse of central North America?
In any case, Volcano World is Great! Your work is appreciated.

Dear Dick,
You were probably near the summit of Soufriere Hills. There are a few
lava domes there. Most of the rocks at Soufriere Hills are andesites
(mean SiO2 58.8%).
Why North Dakota? As much as Chuck and I like volcanoes what we really
enjoy is extremely long harsh winters. What better place to be?

P.S. It snowed here three days before fall officially started.
