The National Geographic Society is a global nonprofit organization committed to exploring and protecting our planet. They fund hundreds of research and conservation projects around the world each year and inspire new generations through our education initiatives and resources.
We have been invited to be a part of this project twice by Bil Philips from Speleotech. Both in 2013 and 2015 we have been guiding some of the members of the National Geography Society. Great honor and great experience, not to mentioned the hard work.
