Darn, I could have given you one

I cannot speak to your preferences about post processing, but I have been known to shoot a 16mm (full frame) or 10mm (crop) in situations that really don't DEMAND that wide of a shot, but then correct the perspective in lightroom and/or photoshop to create an image that is more like a 20-22mm (FF) or 14mm(crop) than has very little warping and skewing at the edges. I liken it to carrying an umbrella if it might rain. If you find you NEED the umbrella, you are covered, but if you don't, you still get a great shot.

Thank you. I use Photoshop Elements and am learning Lightroom now. I've decided to bring it after all...

Thank you everyone for all your help/suggestions and great photos! Decided to take the 16-35. Leaving tomorrow AM. Researched suggested settings for rain given it is forecast to rain all but one day! Linda

Nice photos !
A point of clarity, the OP has a 5Dmk4 which is FF.
The photos posted here at 18mm which are 24mm equivalent. (ie the 24-105 at the wide end on FF is the same as 18mm on an APS-C.)
...but your point is taken. And others have posted about cropping later (as long as your intention isnt to make a 20"x30" for closeup viewing). The 16-35 has great resolving capability so cropping
on the 30mp 5DmkIV will still leave enough sharp pixels for larger prints.

The key point remains, if you have to leave behind either the 24-105 of the 16-35.....the 16 gets the boot.
If you can bring them both, do it !
...however you most likely will not be changing lens in a heli (I was not allowed to even bring them on the heli in Hawaii) so you pick one and live with it.

Some have posted about using the 70-200mm. I had the 70-200mm 2.8 on my 5DmkIV and my wife had the 16-35mm on a 70D when we went in the Heli.
Most of the favorites were from @ 200mm. (Cruise ship, Waterfalls lava flowing into the ocean). Loved the wide shots but once you have 2-3, the rest are the same.
If the glaciers have waterfalls, crevasses, or there is wildlife like bears etc then the 200mm comes in handy.
Hence the 24-105 recommendation. YOu can still get the wide angle shot and get some length too....

I took both look lens,the Canon G3X and a travel tripod. Heavy but on smooth surfaces can drag the bag!

Thank you again everyone for all your suggestions. I learned great deal.

I never understand these questions about taking a lens or not for a certain trip, espescially if someone already owns mentioned lens! If you already have said lens, you know what you get from it, how it handles, what sharpness to expect, etc. So there shouldn't be any questions!!

Normally, I would agree with you. But, I had just purchased the lens for it looked intriguing to use. So, everything you said above isn't applicable. As it happened, the helicopter ride/dogsled run were cancelled due to heavy fog. Did use the 16/35. Preferred the 24/105. Need more practice with the other lens!
