The development of the Landscape Evolution Observatory is the first major renovation of Biosphere 2 since it was constructed. Scientists plan to study how water moves through mountain landscapes and how ecology and landscapes co-evolve in these unprecedented, one-million-kilogram experimental structures. Like us on Facebook and follow the amazing LEO Experiment behind the scenes. Learn more about the project.
