CLIVE -- Clean-up crews are scouring Utah's west desert for unexploded World War II-era munitions scattered across federal range lands that are open to the public.
The U.S. military says it did an incomplete job decades ago collecting shells, grenades and land mines -- some unexploded -- from areas around Dugway Proving Ground.
The Deseret News reports that crews so far have found hundreds of unexploded artillery shells, a live hand-grenade and land mines.
They've also hauled away tons of metal debris, mostly shrapnel from artillery shells.
The cleanup is a project of Hill Air Force Base, the Bureau of Land Management and the Utah Trust Lands Administration.
The BLM's west desert district manager, Kevin Oliver, says the effort will cover thousands of acres and take up to 10 years.
