Last weekend, some ultra-powerful movers, shakers, and carvers of our planet caught ScienceBloggers' attentions. First, researchers debated the potential for Mt. Saint Helens to form a supervolcano, an extraordinarily large volcano with the potential to cause massive wildlife destruction and devastating impacts on climate. Bloggers also discussed two megafloods: one that permanently separated Great Britain from continental Europe, and another that firmly established the topography, soils, and agriculture of the Pacific Northwest. While the Pleistocene epoch may not have been the most turbulent in Earth's history, it was clearly far from quiet.
