Nick,I’ve been following the work of a young German photographer Florian Schulz (of “Yellowstone to Yukon: Freedom to Roam: A photographic journey” fame). Florian won awards in the BBC Wildlife Photographer of the Year Competition and in the Nature’s Best International Photography Awards. Florian has dedicated most of the last decade to photographing the Yellowstone to Yukon (Y2Y) expanse and inspiring support for its preservation.
You should head to Bozeman the next time Florian is here - he's done 2 slideshows in the last year - signed my copy too. Nice guy to chat with.
