Columbia Gorge Discovery Center will host its fourth annual Columbia River Indian Autumn on Saturday. The Discovery Center’s Mikey Goyette says admission will be free, with the event featuring artisans, musicians, cultural dancers, storytellers, and vendors from the regional Native American community. There will also be a salmon bake at 11:30 a.m., with a cost of $20, and tickets for that are available at gorgediscovery.org.
