how do the extra controlled tags work? Can you apply for more than one controlled elk hunt if one of them is the extra tag hunt?

Answer:

There are extra tag hunts offered for the deer, elk and pronghorn controlled hunt draws. They literally allow you to hunt for a second deer, elk or pronghorn if you are drawn.  You can apply for one "regular" controlled hunt and one "extra" tag hunt for the same species, possibly drawing 2 tags for that species.  Or you can hunt with one general season tag and one extra controlled hunt tag the same year.
