To the casual hiker there are no signs of life in the dark shadows of the boulders guarding the Yellowstone River Valley. But while the intruder carefully picks his way over uneven rocks, there are sets of eyes cautiously watching his every step.
As he gets closer to one pair of eyes, they fade to black, then slowly reappear undetected in a different shadow.
The intruder notices a bouncing tail in the distance and instantly marvels at the sight. His suspicions were right – he has found a marmot! He catches glimpses between branches and rocks as it effortlessly glides over the rocky shoreline. He tries to get a photograph but the marmot has melted into the terrain.
All the eyes continue to watch as the intruder makes his way up and away toward a bison path. If he had looked back, he would seen a nose peaking out here and tail sliding around a shrub there. But he doesn’t.
The intruder disappears and the boulders once again come alive with marmots scurrying around their rocky home.
