When you want to find a wolf, find Rick. You shall know this ranger by his yellow vehicle, in which he carries the tools of his trade, including his spotting scopes, binoculars, and an antenna (to pick up signals from wolves wearing radio-transmitter collars). Here Rick is unwittingly posing - in reflection - for his portrait while out looking for wolves near Mammoth Hot Springs.
To view my brother Dan's Yellowstone images, which he made on the same trip, go here.
