Alan Barrett Images | The Bigger Picture | Yellowstone in winter 1

Yellowstone is a fabulous park at any time of the year, but in winter it takes on a magical quality. It can be very cold - and moving around can be a trial - but once one comes to terms with the constraints imposed by the conditions it can provide an immensely rewarding experience to the landscape photographer. The colours are much more muted in the cold, particularly in the hot springs, and at times the scenery is almost monochromatic, but the very starkness provides a beauty of its own.
