Most of the elk hunting advice/tips I have heard over the years seem to been very location dependent in my experience. One area in WA I have hunted for 30 years has the tall dark timber on super steep slopes. The elk (and bears) use it heavily in August when certain mushrooms are at their peak. They move out of those areas during the rut and don’t eat the mushrooms anymore after the first hard freeze. They use these areas again in late Oct-Nov before migrating out as transition zones and also to bed in during extreme weather. When we have cow tags, still hunting through those areas is super productive. Seems like we are making a lot of noise and rolling rocks, but we have shot a lot of elk point blank walking up on them bedded. Also seems like you can see a long ways in that timber, but the small benches/beds can conceal them well.
Other areas in WA and Idaho I don’t see the elk utilizing that country as much. I think it all depends on the surrounding landscape and what it holds for cover, shelter and food.
