I suppose they could try starting up a fresh new AM there but I know nothing about what's available for use there.
I do know that 600 and 850 are still available, but if they're hoping for a clear channel frequency, it's not possible -- both 600 and 850 would have to broadcast directionally and/or at a lower power to protect class-A clear channels on these frequencies; don't know about 600, though KOA Denver is a Class-A that broadcasts on 850.
