Yes looks like your on the right track.
Maybe. . . There might be elk there, there might not.
Do you need fifty spots marked on your map? It's a good start. First year you might cross off 30, or you might only make it to 3-4 because you picked good areas and they are holding elk.
But you have to remember. If you're picking out obvious "elky" areas, everyone else. has seen the same thing on Google Earth and dropped a pin to check it out.
As others have said, boots on the ground will separate out a lot of what you need. Takes a few years to start bailing down an area, and about the time you get it dialed in, something changes or 47 people show up and you have to start all over. But that's part of the fun!
