I have never hunted that country, but I have floated through it. Here are some pics from two summers ago of the area you are talking about. It is very steep and nasty, but beautiful country.
This is looking upriver from below the Bridge that crosses from the Thomas Creek Strip to the Little Creek Guard Station.
There is a ton of really neat history in this area. The Sheepeater Tribe called this place home, and left numerous reminders that we are the latest in the long line of hunters that have frequented those mountains. This is the Cameron Creek Panel which is directly across the river from Little Loon Creek. If you look closely, you can see bowhunters and their quarry.

Not exactly sure where on the river I was when I took these next two, but they are from that general area.
As you can see that is some rough country. If you are at all interested in the history of the area, there are some really good river guide books full of interesting info, maps, and photos.
This is my favorite of the three guides I have read:
Previous Model: The 4th Edition of Matt Leidecker's Middle Fork of the Salmon River Guide Book delivers mile-by-mile rapid descriptions with detailed maps and photos all printed on waterproof paper.

Oh, and if you decide to cross the Middle Fork in a little raft, be very careful. That river is fast and has a lot of big rapids. I wouldn't want to go in that time of year without a life vest and a waterproof way to get warm and dry quickly once you get back to shore.
