I really liked Bar's response. He said "My style of hunting is .... So, ..." What you look for is dependent on your style of hunting and the area you will hunt. I tree stand hunt, so ...
If I will be hunting a semi desert area I look for water, then benches and bedding areas. I like to see game trails coming together. One thing I could care less about is aspect. Elk are not limited to north slopes at all. I have found them on flats and bedding in niches on generally more open south facing slopes.
Look for areas where you can expect to find elk based on your style of hunting. Look for spots where you can take advantage of their vulnerabilities. If you are not looking for those things, then look at habitat and see if and how you can best access it and hunt it. Just my thoughts.
