All you really can do is find a good spot and watch. Find a trail or watering hole with food and cover nearby and take a good pair of binocs. Make sure you can see a big area. If the elk hear you they will hide but they aren't far unless the area has a ton of pressure. When you are walking up to your spot take a cow call and just give it a call once in while as your walking and they'll just think you're one of them and won't spook much at all. Sit long enough and the elk will move, it may take a few hours so dress warm and take a pad to sit on.
