Elk can cover a lot of ground in a short time, and live in the thickest, roughest country you can find. They are frequently in groups, more noses, eyes and ears. The lead cow will guide their movements. Be prepared physically to cover ground, look, listen, and use good binoculars like 8x40 Nikon. The weather is a big factor in the rut in the areas I hunt. If they are undisturbed, the will stay in an area, bust them and they will go a long distance and won't be back. I prefer not to call too much, you can certainly over do it.
One time while hunting in the Blue Mtns of SE Washington, I walked into a herd, bedded down on a ridge. The fog had rolled into the valley and then up the ridges and it was so thick you could only make out a tree if it was within ten yards. I only saw, one or two, there was one cow that past me about five feet. They couldn't see either and were actually nocking over small firs, when things exploded. I followed one cow down the mountain, and she jump off several rock ledges ten to fiften feet high in steep terrain. I knew I'd never see them again, and was only interested to see how far see would run. I never found out, because she was still running when I got down the mountain.
Hunt alone or in pairs, if there are other hunters in the same area, go find another area.
