The "Science Behind" series at Walking Mountains continues on Wednesday at 6:30 p.m. with the "Science Behind River Dynamics & Rafting." What substance is more necessary to our existence than any other and is the only element to be naturally found as a solid, liquid and gas? Water. Right down to the molecule, our lives depend on it. Join us as we explore the path water forges through our valley. How has the landscape of the Eagle Valley been formed, and what demands are placed upon the water flowing through? How can we read the water as it moves across the landscape, and how does this affect the ways in which we can enjoy this resource? Walking Mountains Science Center will explore these dynamics in conjunction with Lakota River Guides as part of our the monthly "Science Behind" series of classes. Come gain a greater perspective on how to identify rivers and features suitable for rafting. Participants of this class will be eligible for a $75 full-day rafting trip with Lakota valid through June 15 - a portion of which is donated to Walking Mountains. Seating is limited; call or email to reserve your spot: 970-827-9725 or firstname.lastname@example.org.The Science Behind series of classes highlights useful and fun skills that have underlying scientific principles. Each class provides a hands-on, interactive component with instruction from a local subject-matter expert and a Walking Mountains educator. Classes are held once a month at Walking Mountains Science Center in Avon. Next up in the series is "The Science Behind Worm Composting." Learn to compost in small spaces and take home your own worm bins. This one is back by popular demand in case you missed it the first time around! It will take place June 13 at 6:30 p.m.
