Roosevelt elk are more like whitetail then elk. They form habits and travel routes. This being said, one thing will make you successful. SCOUT!! Spend 3 days in the woods scouting for everyday you plan too hunt.
I used to spend the summer in the Hoh river drainage from the park to the park. We checked every hole and thick spot in the drainage. Usually by hunting season we had 4-5 herds pattened and did very well hunting them. We didn't always bring one home but we were in them everyday.
