Sunning Sheep

The bighorn sheep sometimes come off Miller Butte on the National Elk Refuge in Jackson Hole to look for food. About 50 sheep inhabit this area. They range from the large rams to females with young to this young ram. Once summer arrives, these creatures will be back to the high ledges and very difficult to spot.

Bison Butting

Both male and female bison settle their differences with the use of their massive heads and horns. The skirmishes often are over within a few seconds and usually do not result in serious injury.

Gone Fishing

A Great Blue Heron slowly but deliberately moves through the shallow water at the edge of the Snake River, searching for small fish or water bugs.

Surprise Storm

A hummingbird shivers on an aspen branch after being caught in a late spring snow storm just outside the northern boundary in Grand Teton National Park

Young Pair

A pair of mule deer venture out in early morning following a spring snow shower the previous night in Grand Teton National Park. Spring comes late in the high country. It is not unusual to see rain and snow through the month of June.

Look Both Ways

Just after dawn in Grand Teton National Park, a herd of elk watches for traffic before it crosses from feeding in the open flats at night and moving to the security of trees along the Snake River. The elk herd in the Greater Yellowstone ecosystem numbers 100,000, the largest in the world. Yet, these creatures are difficult to spot during the day. Sightings like this one are most common at dawn and dusk.

Moulton Barn

In the 1890s several Mormon families moved to Jackson Hole from Utah to escape drought. They settled in an area now called "Mormon Row." All but one family left, selling property to Grand Teton National Park or to John Rockefeller, who donated land to the park. Several historic barns and other buildings remain.
