Consider this:
Region 3 (SW MT) has ~60,000 elk. The fact that you didn't see an elk during the time of year when they are most vocal/active means you were nowhere near good elk habitat, regardless of distance from a road or trailhead.
You need to focus on what good elk habitat is and they're behavior based on season. If you dont know, there is plenty of books/podcasts/whatever you have access to.
