Im hiking down to Havasupai Falls in the Grand Canyon next week. I'm trying to limit how much I carry down with me. I'm trying to figure out what lenses to bring. I have Canon 5D MkIII. My lense choices are 17-40, 24-105. I also have 70-200 and 85 and 135 Prime. Any advice would be appreciated. I think I only want to take two of them.

Any other advice about the hike would be appreciated.

Thanks,

Dave
