Samuelcmm;
I've lived & hunted most of my life in Wyoming & Montana. Much of that time I was also a professional ski instructor, and as such had to deal with people suffering from altitude sickness. Which can be deadly, though usually not. The point is, elk are frequently found in areas where it's possible to hunt both sides of the same acre of ground. It's high, the oxygen is thin, the ground is steep, and there may not be trees. Crossing a scree slope that's got 4 inches of snow on it is a real adventure, particularly if it's getting late & a storm is coming in.
Your gear needs to be light and warm. That includes the gun, which does not need 50 rounds of ammo packed with it. Start getting into shape now & get serious about it. A year from now you'd better have stayed serious about it. And when it comes time to hunt it's critical you've stayed serious about it. A ten-minute cardio workout is not going to build the extra red blood cells you'll need. As was suggested, come out west & summer hike some high trails. You'll see that I'm not tryin' to fool you or exaggerating.
