Enjoy these photos of black bears, grizzly bears, and cubs taken during the month of May in Yellowstone National Park.

February is a cold month in Yellowstone, filled with snow and ice, but it is a beautiful time. It is also mating season for wolves so they are out and about.

December… the crowds have left, the snow is accumulating and the animals know that they have a long cold winter ahead of them.

The secret to photographing Yellowstone in July is to know where the action is, hike there shortly after sunrise and spend the entire day there.

In May, the crowds have not filled the park (yet) and all of the wildlife is starting to recover from winter’s extreme cold.

March… the month of the wolf. With winter loosening it grip for the first time the Park’s wildlife begins to come out including grizzlies.

October...Fall colors, elk rut, cool mornings, steam on the water, less visitors and (often) magical light.

I take advantage of the passes as they are cooler, less crowded and at the peak of summers bounty.

April can be a mystery box of opportunities in Yellowstone, as it seems each year the snow levels and activity are completely differen

Wolves are out and about, their prey is in the valley, so they too are within sight of the road that runs through the "Northern Valley."

Wolf 832AF (AKA "06" - for the year she was born) was the Alpha Female of the Lamar Canyon Pack killed on Dec 6, 2012 as part of Wyoming's wolf hunt.

Fall brings about a boost to wildlife activity in the park. Most visitors come to see and photograph the elk and moose ruts.
