There is perhaps no more reliable a visitor to backcountry campsites than ground squirrels and chipmunks. There was one in Yellowstone, and another in Glacier. This one was hoping to share our breakfast on Lower Kintla Lake in Glacier National Park. I never let them get to my food; it’s not good for them. But they can appear out of nowhere — and kick up a lot of fairy dust in their wake — and sometimes I’ll trip the shutter before one of my companions waves off the intruder. This was my first shot of the morning.
