Nothing personal, but in my experience and opinion this is an exceedingly bad idea that does a lot of harm to your chances of actually getting close to elk when they are up and moving and vulnerable. Every fall I see elk get blasted out of their bedding areas by goofballs that think they can sneak up on them bedded in the dark timber, and admittedly I've done it myself. These are not deer that run a quarter mile and forget about you, elk might not stop until they're in the next county and often won't return for days. I'm not saying this can't be done, but unless you actually see an elk bed down and can carefully plan a stalk it's a fool's errand and can quickly turn thriving mountainside echoing with bugles into ghost town.
What He said !
I knew somebody would post after me and say - well, I killed 28 bulls last year doing that, with one arrow (hyperbole intended as friendly ribbing). As I mentioned, not saying it can't be done, and I recognize some have success at this, but certainly not most. My whole point is that the vast majority of the time this method results in nothing more than running elk out of the area and making them more skittish and pressured. Everybody's going to hunt how they want and try the things they want, and everyone and every place is different. But most hunters are going to do well to avoid this method.
I think this is the best advice above, the important part is making sure your scent isn't going into somewhere elk are hanging out, nothing clears elk out faster than people wandering around midday...
The same can be said for every other hour in the day as well. People that hunt like idiots are going to blow elk out regardless of what time of day it is.
Can't say how many times I've watched hunters move into the thick stuff and bump a herd out and not even know it, then come out and go off in a different direction. Meanwhile the elk moved into the next stand of timber and bedded down again. Bingo!
