Welcome to the forum and thanks for the trailcam porn.
Two questions I see is 1. Where did the elk go, and 2. Did the wolves eat them? I'm not a fan of the wolf program. But, noting that you've captured several animals on camera within a week or two of your hunting trip, I would suggest that they didn't all get eaten by wolves. It could possibly be that once the bulls connected up with the ladies and kiddos, they moved them out to an area where they felt more secure, for whatever reason. And, I wouldn't be at all surprised to learn there were wolves in Siouxon. They're in 560 and up around Mt. Adams. 572 is not a stretch.
