Based on my experience, you will probably need additional reach however.
We visited Alaska for 3 weeks in June, 2014. I took my 70-200/2.8 II and 1.4x and 2x extenders and also rented a Tamron 150-600 for use on my 6D. I used the Tammy extensively on a whale watching cruise and at Denali National Park, but not much the rest of the time, the 70-200 with and without extenders were sufficient. I found the autofocus of the Tamron mounted on my 6D inadequate much of the time. I got plenty of good shots with it, but plenty of potentially good ones that were OOF. I was pretty happy with the combo initially, but after going back through the shots, disapointed to see how many were slightly out of focus. Part of the issue was my 6D, which as we know isn't great for action/wildlife, but my results with the 6D and 70-200 and extenders was much better. I took a bunch of eagle shots, many in flight, with a 70-200 (yes they were that close!) and the hit rate was excellent - with the same 6D and limited skills.
If I had to do it again, I would have rented a Canon 400/2.8 II for use with and without extenders. I recently added a 5DMkIII which would have helped if I had it last summer. If this isn't in your budget, I recommend renting a 400/5.6. I recently rented one of these for a trip to the Everglades and had excellent results (on the same 6D) shooting birds and alligators. This is pretty much a "good light" lens, but I think it would be a great option for Alaska, especially since it will give you 640mm reach your 60D.
Good luck with your equipment decision. Be sure to post some of your AK shots when you get back!

Sounds like the tamron could have benefitted from AFMA

Personally, I don't think the f2.8 is worth the weight and bulk for travel and outdoors, one of the reasons I've got the 70-300L. Remember that 1 stop of more light probably won't save the day, for "shoot in the dark" you'd rather have a really fast prime like f1.4 if something moves - otherwise just crank up iso on the 6d.
The f2.8 lenses are more about thinner depth of field, and question is how often you'll really see much of this effect for general outdoor shooting esp. as the danger for out of focus shots rises if you're not careful.
nc0b said:Thanks for the comments. I will take the 70-200mm f/4 IS, the 24-105mm, and 400mm f/5.6. My wife may do some shooting, too, so should I also take the 300mm f/4 IS, or is that too much baggage?
I shoot indoor dance, and the f/2.8 is fantastic, but that is a totally different venue. On Easter Island and Machu Picchu I certainly didn't need f/2.8.

Northbird said:Yes, +1. Although for size & weight I prefer the 300 2.8 with extenders for effective reach of 420 F4 and 600 F5.6. Pair it with the 7D II for extra reach and life is good. Image quality with 1.4TC is great. With the 2.0TC technique is important and there is a noticeable decrease in image quality.
nc0b said:I appreciate the suggestions. As far as what I will be shooting, and do I need something wider than 24mm, I don't really know having never been to AK before. I have an 18mm Zeiss, which isn't all that large and easy to include in my kit. I didn't miss it on Easter Island or Machu Picchu, as the 24-105mm on the 6D and 70-200mm f/4 IS on the 60D worked well. I never considered renting the new 100-400mm II. I have no idea what that would cost for three weeks vs. just buying it.
