The Columbia Gorge Discovery Center will rededicate its all-ages interactive activity center on Saturday.  The 900-square foot Explorer Room was closed over the winter for remodeling.  Center Marketing Director Mikey Goyette says the room has been stocked with fun, hands-on activities for everyone.  Goyette says the Discovery Center received numerous donations to do the renovation, including more than $17,000 from The Dalles Kiwanis Club.  The room has been freshly painted, carpeted, and furnished with new UV-coated windows, kid-friendly furniture, a large screen with live video of the museum’s Bald Eagle habitat, a mural of the landscape of The Dalles, and a reading nook.  The ribbon cutting is free and open to the public and will take place Saturday from 2 p.m. to 3 p.m.  Museum admission is free between 1:30 p.m. and 3:30 p.m. for the ceremony.
