Cnances are, depending on where the property is, you won't even be in an elk area! So I wouldn't count on elk. But Newcastle is well known for it antelope. I'm sure there will be some mulies, maybe even white tails. And it's also a great area for Merriam Turkeys! You can shoot turkey in Wyoming with centerfire rifles .22 mag and bigger.
Lots of info on the Wyoming G&F site. Dates, licence fees, drawing date deadlines!
The terrain is arid sage with pine covered rimrock and gentle mountains.
Very close to some cool ****. Devil's Tower, Mount Rushmore to name two.
