If you ever plan a trip to Alaska i highly recommend the flying tour of Mt Denali with the glacier landing option. It was about $560 per person, but worth every penny of it. The plane climbs to 21,000 feet as it circles Mt Denali on its way past the summit. You're above the clouds and can even see hikers at base camps preparing to summit. The you land on a glacier for about 20 minutes of exploring, wonderful views, and a snowball fight. We stayed a few nights in Talkeetna Alaska and this was my favorite part of the Alaska trip. We went in June for the longest day of the year.
