Recent Activities

June 2014 - River Race Tabling

Our May meeting featured an extremely entertining and informative presentation by Frank Nederhand, who spoke of his experiences in the mountains of Peru, as part of the Cordillera Blanco Peru Envionmental Expedition. This expedition collected information on pollution and other environmental issues in Peru. Frank had a great slideshow, and brought along a bit of his mountaineering equipment as well.


Centennial Group had a booth at the annual River Race. We had activities for children and sign-up sheets and petitions for adults. It was a super successful event -- a thanks to all Sierrans who volunteered.
