The Columbia Gorge Discovery Center and Museum has unveiled a new logo and updated its website.  Center officials say the new logo, a hand-drawn spiral with compass points, represents the journey of discovery historically associated with Lewis and Clark and expressed through the Center’s programs and exhibits.  The logo features an earth-toned palette that reflects Oregon’s various climates, from high desert to verdant forest.  Center Visitor Services Manager Kristen May says the rebranding effort intends to deliver a message that reflects the Center’s mission.  Marketing materials will be updated in coming months.  A Paul Allen Family Foundation grant funded the project.
