Forest Service officials have posted warning signs around a popular hot springs in the Colorado Rocky Mountains while they decide what to do about the frozen carcasses of dead cows found inside a nearby cabin.

Options for removing the carcasses include using explosives or burning down the cabin. A decision is expected by the end of the week.

Spokesman Bill Kight said Tuesday water samples have been taken to determine if the hot springs was contaminated by the dead animals.

The Forest Service is also trying to determine if the cabin is contaminated with asbestos.

Rangers believe the animals wandered into the cabin during a snowstorm but then couldn't find their way out. Air Force Academy cadets found the carcasses while snowshoeing in late March.
