Dear Lavatube Afficionado,
The GSA 2009 field trip, 421 - "Lavatubes of the Mount St. Helens Region" took place on October 17th, 2009. Participants were able to observe several examples of the large number of lavatubes located in the vicinity of this famous volcanic region and thus gained a taste of the wonders to be found in lavatubes all over the world. The trip was very popular and 41 people participated in the events.
The diverse group was composed of many experienced lavatube cavers and scientists and people who had never been in a cave before. Various aspects of the geology, microbiology, and mineralogy of lavatubes and their extraterrestrial occurrences were discussed through the day and an open interchange of information and ideas made the trip both relaxed and stimulating.
And on a sad note, Dr. Anton Brown, one of the participants on the field trip, passed away the following Monday at GSA. He will be missed by all who knew him.
