I thought the 26 glacier tour was out of Whittier or maybe it was in Prince William Sound, but I can't remember. But, if you went from Seward, then yes. Ailik Glacier is the glacier I remember seeing and you pass thru Resurrection Bay. We saw a lot of sea animals including several humpback whales.

We were in Big Bend in 2011 during Spring Break.
We enjoyed Big Bend. I've been to Guadalupe once. I am going back to Guadalupe and Carlsbad the first week of Nov and doing a little backpacking there. This will be my 4th trip to Carlsbad. White Sands National Monement is also kinda cool. I haven't been to Saguaro. I have been to all the Utah parks 2 or 3 times. I have yet to visit Black Canyon of the Gunnison. Mesa Verde is a really good park as well.

I like Great Sand Dunes in Late May when Medano Creek is running. I would think that the primitive road would be good during Fall Foliage too. You definately need a 4 wheel drive though.

We haven't been to Denali. Wrangel is really really high on my list

You're right, we took the 26 Glacier Cruise out of Whittier, thanks for reminding me.
Your pictures are beautiful!
