Yellowstone National Park is the oldest national park in the United States, having been established on March 1st, 1872. While Yellowstone is home to incredible landscapes and countless geothermal features such as Old Faithful Geyser and Grand Prismatic Spring, it is also a wildlife photographer’s paradise. This winter, OM SYSTEM Ambassadors Tiffany Taxis and Arthur Lefo visited Yellowstone in search of capturing incredible moments to add to their wildlife portfolio.
