Due to all the pressure, just because you have not found any fresh sign yesterday or today, does not mean elk won't move in overnight. Elk can, and will, move a long ways quickly.
A couple years ago, we'd been hunting for days without seeing a track. Then we got 6" of snow. Driving down a back road heading to camp after dark, we found lots of elk that had just arrived from somewhere, within rock throwing distance from the road, right out in the open sagebrush. The next morning before light, we were back and the elk were still there. We sneaked in through the sagebrush and when it was light enough to shoot, bang, bang, 2 in the bag. We were even able to get the truck through the sagebrush to load them up.
