Firefighters say a fire smoldering in a mountain pass on the outskirts of Tucson is now 80 percent contained and much smaller than previously estimated.
Coronado National Forest officials say the Redington Fire has burned 30 acres in Redington Pass between the Catalina and Rincon mountains.
They say a previous 125-acre estimate was off because of steep terrain in the fire area.
The fire started late Saturday and crews were assisted early on by air tankers that dropped retardant.
Fire officials say some equipment has been released to other assignments but that firefighters continue working to suppress hot spots.
The fire was human caused. It remains under investigation.
