Yellow Sage? Spokane River Factoids

On the drive out to the Fort Spokane boat launch on the place where the Spokane River empties into the Columbia River, we passed acres of YELLOW blooming sagebrush. Yellow? I thought sage bloomed purple? Riders of the purple sage and all that?

What do you know about our beloved Spokane River?  It's 111 miles long going from Lake Coeur d'Alene to the mighty Columbia. Long considered sacred to local Native Americans, the river drains an area of 6240 acres. Four dams on the river provide local electricity. West of Spokane, the Nine Mile Falls Dam creates Long Lake where the fishing, boating, water sports and swimming abound. We are lucky and blessed to have such a wonderful river. Yes, "a river runs through it," through Spokane.

P.S. Three days later: Sharon, sweet friend in Wenatchee, said that the plant is probably Yellow Bitterbrush. Thanks!
