National park photo ops: Yes, you can catch Alaska critters through a tour bus window

With one road servicing Denali National Park & Preserve in Alaska, most access is arranged by tour. There are grizzly bear, caribou, Dall sheep and moose in the area. Most are visible with telephoto lenses.

This caribou was photographed from the road with a 400mm lens. Since I was on a tour bus, I ended up balancing my lens on the open window.
