Antarctica is the highest, driest and coldest continent on earth, holdling 90% of the world’s ice and 70% of its freshwater. If the ice melts sea level will rise about 60 m and inundate more than five million square miles of land. Early explorers referred to it as a place devoid of life, and idea that persisted for more than 80 years. Recent research has shown that huge river basins and some of our planets largest lakes exist beneath more than 2 miles of Antarctic ice that subglacial ecosystems in Antarctica form the largest wetland on our planet. Microbial organisms mine the energy in rocks while mobilizing nutrients that fuel life in the coastal regions of Antarctica. Professor Priscu will present the events leading up to these discoveries and how they have transformed the way we view the Antarctic continent.

MSU Wonderlust is a high-qualitycommunity resource for lifelong learning for the Bozeman area.  Here is university-quality instruction by experts in a huge number of subjects, some multi-week courses, some one-off events.  They come free of homework, exams, or papers: The MSU Wonderlust experience is just a chance to learn new things or review things we’d already studied.  It was also an opportunity to meet people with a wide variety of interests.

Last year we transferred to operations to MSU and took on the supportive role as "Friends of..."  This past year was our first as Friends of MSU Wonderlust with the mission to support and promote MSU Wonderlust.
