Yellowstone Backcountry Lens Choices

Next week I'm doing a horseback/camping trip into the Yellowstone National Park backcountry to the upper part of Slough Creek. The main purpose is to get to some of the best fly fishing water in the park, but the scenery will be spectacular. I have a D700 and a few lens choices. We are very limited on what we can take, so the dilemma is which lenses to take. I think practicality and the size of my small gear bag limit me to two only, but which two.

Here are my options (all Nikkor AF-S):
50 f/1.4
16-35 f/4
24-120 f/5
105 f/2.8 macro
70-300 f/4.5-5.6

I'll be taking photos of my friends fishing, their catches, but lots of beautiful landscapes also. Low light capability at night in camp would be a plus too.

I think the 24-120 is a no-brainer. My real dilemma is between the 50 prime and the 16-35.

Thanks in advance for your recommendations and expertise. Regardless of which lenses I take, it'll be a wonderful trip (unless I have to opportunity to get close shots of a grizzly!).

There is only you and your camera. The limitations in your photography are in yourself, for what we see is what we are.
