We thought we would try to see Denali (AKA Mt. McKinley) after getting rained out last year staying at one of the Kantishna lodges during a week of rainy overcast weather.
We got one of the mountain facing rooms on the top floor at the Talkeetna Alaskan Lodge. Stunning view. Good service. Good food (really!). Excellent large room.
I used a Canon 20D with a 100-400 mm zoom. The picture is really a panorama of two pictures. I don't recall how zoomed out the lens was.
