Sometimes the prey is tough...

May is the time for newborn bison calves in Yellowstone.

 

Female bison group together to protect and raise their young and grizzly bears are out looking for almost anything to eat.

 

 

On this day in the Lamar Valley a large grizzly was eating grass while a group of bison cows and calves moved past. The grizzly made sure to look like salad was all that was on it's mind as the bison calves went by.

 

 

 

Though the bear hadn't made a move towards them, the bison cows hurried their calves past the big bruin.

 

 

 

Running at least two hundred yards. Once the cows and calves were out of the picture...

 

 

 

some cows without calves went to take care of the potential problem.

 

 

 

At first the bear acted nonchalant as the cows approached.

 

 

 

Until it finally turned and ran towards the Lamar River. 

 

When the bear was out of sight the cows stopped their pursuit and returned to the herd.

 

Later in the afternoon the grizzly bear was back in the area eating grass and keeping an eye on some other bison calves.

Some of the beauty of Yellowstone Park

Geothermal features such as this hot spring on the bank of the Gibbon River are called chocolate pots.

White Dome Geyser erupts pretty frequently allowing for lots of chances to get photos like this one.

Roaring Mountain no longer makes the loud noises for which it was named, but it's still a cool feature in Yellowstone Park.

If you hike up Electric Peak in the northern part of the park this is the view you will get looking east.  The little lake is Cache Lake, Sepulcher Mountain is behind it, and Bunsen Peak is in the distance.

This is Canary Spring at Mammoth Hot Springs.  This photo was taken several years ago and the spring looks different now due to changing water flows, temperatures, and other variables.  One of the very cool things about Yellowstone is that it is always changing, it's never the same.

Fall is a beautiful time to see the park.  Here huge columns of steam rise from Excelsior Geyser and Grand Prismatic Spring with the Firehole River in the foreground.

Winter in Yellowstone can be very cold and very beautiful too.  Clouds drift above snow covered hills in the Lamar Valley.
