This is a gallery of images from a photo tour to Yellowstone National Park.I spent a week in the park with Wild Nature Tours in January, 2011 . My guides were Juan Pons and George Wuerthner. Yellowstone is a magical place especially in the winter. The harsh conditons are very stressful for the wildlife. I felt very fortunate to view the wildlife in their natural environment and observe their daily struggles to survive the long Yellowstone winter.
