You are correct to a point with "keep it mobile" but more importantly you have to think like an elk. In any scenario elk think about 3 basic things.
1) Safety
2) water. They have to water everyday and will.
3) Food, but they don't need to feed to max capacity everyday.
Safety from humans is a given at night and at that time they will travel what you may consider long distances through rough terrain (1 + miles) to you, but a short, easy travel time to an elk to get food and, or water and be gone before daylight.
Elk like heavy, steep, but not always, timber to bed in with benches that are relatively flat, but can be very small in size, just big enough for their body or just big enough for the herd. Ideal is a water source very close by, but when pressured they will for go the water source for SAFETY !
I have found the best ridges to hunt are ones with very steep terrain on one side and mild terrain with bedding options on the other. If you look at your topo maps you will find many of these scenarios in the area you will be hunting. How do I know ? I just got a leftover "B" tag for the units you will be hunting for the same dates. I already filled my Archery "A" tag with the bull pictured on September 24th in an unit that was supposedly a "over run with hunters and all the elk are on private". I scouted the area on my OnX using exactly what I described and could have killed an elk everyday be it a cow or bull. I passed on 2 small bulls before killing this one on day 4. I knew where he was bedded as I put him to bed in the morning and set up for him at the closest water source in a remote meadow and at 6:25 PM I put the arrow in him. He went 70 yards and dropped "dead as a door nail". This is not just a one time thing as I have killed many elk using the same concept.
Elk almost always travel ridges when moving point to point and 1 of there downfalls is they like to travel through saddles between ridges and is an awesome place to sit and wait at first and last light, especially if the saddle is between bedding and a water source. Once an elk gets out of his bed to start it's daily routine the first thing they think of is water (Rule #2 above). Water is usually the last thing they do before bedding for the day, also. Get yourself between bedding and a water source, in an area that is showing sign, and you will be golden.
And ALWAYS, ALWAYS keep the wind in your favor. I swear they have the ability to smell a scent down wind, somehow, and for sure will pick you off hundreds of yards away if your scent is blowing at them. No amount of scent lock, wind jammer or any other cover up will fool an elk's nose.
PM me if you would like and we can talk more.
