Pick a unit, look for areas where you can't drive a car. In those spots you can't drive a car find a spot that has some heinous terrain feature that would make it crappy to pull an elk out off that is at least a 90 min walk from the nearest access point.
Be at a vantage point above the hell hole before first light, sunrise will probably be ~6:45am so you want to be there at 6:00am. Meaning you need to leave your truck at 4:30am, so get up at 3:45 or 4am.
Find a couple of these spots and if you don't find elk in the first couple of hours move on to a new spot for the evening, stay till it's dark.
If you are at your truck and the sun is up it means you killed an elk or else you are doing it wrong.
The elk will be pressured so don't glass the pretty meadows they won't be there, instead glass the edges of the dark timber/oak brush thicket/ dense aspen grove, etc. Your assumption should be the elk will feed out into a meadow at night and you are trying to catch them out in the open in the first and last few min of the day. Once you know where they are go kill them.
