This pika thought he was hidden from view and perhaps hoping for something to scavenge after we left the pullout where we had lunch. We were on the Beartooth highway on our way to Yellowstone and Jackson, WY. 

 
The Beartooth is a beautiful drive, ascending to over 10,000 feet in elevation. Lots of switchbacks and shear drops along the way. One needs to stay attentive. 

  
Below is an image of the spire from which the highway got its name. This was taken with the equivalent of a 2700 mm lens.
