Sudden sightings of wildlife are part of the excitement for visitors to Yellowstone and Grand Teton national parks. But most people are there only in the summer. This collection brings everyone year-round coverage of all the parks' animals, large and small. In turn beautiful, amusing, and artistic, Holdworth's photographs take readers into all corners of the parks, in all seasons.

Henry Holdsworth has spent two decades living in and photographing the Greater Yellowstone Ecosystem while not traveling on assignment. His images have appeared in many national periodicals and books. He and his family live in Jackson, Wyoming.
