The first aluminum smelter built in the Pacific Northwest after World War II is opening its doors to the public Saturday to celebrate its 60th anniversary.

Alcoa's Wenatchee Works in north-central Washington is just one of two aluminum plants still operating in the Northwest following the 2001 energy crisis. The other is Alcoa's plant in Ferndale, Wash.

Wenatchee Works employed about 1,000 people in the 1980s, when 10 Pacific Northwest aluminum plants supplied roughly 40 percent of U.S. aluminum. Today, Wenatchee Works employs 450 people.

But the Bonneville Power Administration says one other plant in Columbia Falls, Mont. is considering partially restarting its operations.
