John Weller is a critically acclaimed photographer, writer and filmmaker based in Boulder, Colorado. Nature photography has been his passion since childhood, and after graduating from Stanford University with a degree in economics, John began pursuing media full time. He spent two years in California working for photographer William Neill and then moved home to Colorado, where he fell in love with Great Sand Dunes National Park. For one week of every month over more than three years, he walked with a 54-kilogram pack deep into the extraordinary landscape. With each trip, he further understood interconnections within the ecosystem.
