Lamar Valley Trail - Yellowstone National Park - Wyoming

The most amazing thing about the Lamar Valley Trail is that there are often bison along the trail with no fence separating you from the animals.  The park service recommends staying at least 25 yards away from bison (which is really close).  Just after we took this picture, the herd behind the kids started walking toward us and we had to backtrack awhile until they veered off.  After the hike we talked to a ranger with a scope that told us there were wolves at the base of the mountain which cause the bison to move abruptly toward us. 

At certain times of the year the wildflowers in the Lamar Valley can be spectacular.  Purple seemed to be the color while we were there.
