I think there is still some good elk hunting to be found in Idaho. It appears to me that the wolves have definitely had an impact on the elk herds, and I don't think we have seen the far-reaching effects yet. The elk have done what such animals do to adjust to the new predators, such as leaving the back country in favor of areas closer to human habitation - due to less wolf pressure. From a hunter's perspective (more so for out-of-staters) it makes locating the elk a bit more difficult, but worse yet, as Rik found last year, once the elk are found, there is no guarantee that they will stay in the same place long enough to hunt them.
The Weitas area used to be one of the premium areas in the state for elk hunting (20-30 years ago). The Dept. of Fish and Game has said it is one of the most critical areas for calf recruitment due at least partially to wolf predation. Unfortunately the wolf hunt in that zone has not been as successful as they had hoped.
I don't really know any outfitters I can recommend, but as suggested above, Ted Fry could perhaps help with some information.
