IDAHO FALLS, Idaho (AP) -- Idaho National Laboratory officials say two wolves have been spotted on the 890-square-mile nuclear facility that is off limits to hunters.

INL spokeswoman Carisa Shultz tells the Post Register (http://bit.ly/V9j65r) that workers spotted the wolves Saturday outside the fence of the Advanced Test Reactor Complex.

Shultz says employees are used to seeing deer and occasionally elk at the eastern Idaho site.

Idaho Fish and Game spokesman Gregg Losinski says an elk herd has learned it's a safe place from human hunters so it's likely wolves could figure that out also.

Jeff Gould of Idaho Fish and Game says the wolves are probably just passing through and it's unlikely they'll set up a home range in the desert.

INL officials have reminded employees to be alert when outside the fence.
