Hunt from the top in an area a lot. Our camp spot is on the other side of the ridge top from where the majority of the elk spend their time, then we come over the top in the morning. Typically in our area, the elk have moved down for the evening and are working their way back up in the mornings. Depending on the mountain you're on, you should be able to be well enough above most of the elk to not blow them out. Obviously if a rogue elk moved in say 300 yards below where you roll over the top, they're going to get you but in big country that's a pretty small percentage chance.
Basically, we have good luck with being on the ridge at gray light to start listening for a while, then location bugling from the top. Then we'll work our way along the top bugling every couple hundred yards for the first hour of the day. We try to work the opposite way we had gone the previous day for that first hour or two. If we come up with no bugles, then we'll work back to the start and go the opposite direction. On the day that we don't hear any responses, we basically end up at 1030-11am still on the ridge. We'll usually sit down and chill at that point...been a good amount of times, at least twice during a week of hunting, that you'll end up hearing a bull bugle on their own between that mid morning and mid afternoon time frame. Another note is that we've had the elk within 100 yards of the top in the early morning as well as not getting up to within 500 yards of the top by 10am....so it all is variable.
In our case, we know elk are there so we tend to play it safe and not just go dropping into known areas they bed early in the hunt because if they're not spooked out, they'll eventually fire up, maybe not today but tomorrow. Contrary to some popular hunters, covering ground trying to get a bugle really equates to you having to make big moves to keep finding herds since you're blowing out a lot of them by stinking up a spot. That works if you know a lot of spots but we tend to like to hunt in a hard to get into spot where folks don't usually go and stay there rather than bounce to a lot of more easier to get into spots, since we know they're there and will eventually play. It's all about what you like, but don't think that covering 8 miles and 3000ft of vert everyday equates to being more successful. The elk don't care how much work you've put in.
