I'm not certain what that is exactly, but i believe it is a bird. Probably some sort of owl. Try a birding website to get the exact species. The repetitive nature I heard and you described does not sound like elk. If it were some sort of small mammal, like a squirrel it would not continue all night. So like I said, best guess is its an owl.
UPDATE-because I'm a geek and it was eating at me- I'd now say it is a northern pygmy owl, given your location and the owl calls I was just listening to.
Wind is one of the most crucial variables in any kind of big game hunting. It helps level the playing field between a hunter with a scoped rifle and the game animals being hunted. This is not novel information. Any hunter who has consistent success in the field knows this. I have tried a couple different techniques for keeping track of the wind. Here are a couple.
The most simple and obvious is to just stay cognizant of it. It is amazing how slight of a breeze you can sense if you just pay...
