It's a big weekend for the University of Arizona, their historic tree ring lab is all moved into a new building and they are opening up their doors to the community.
The lab has been waiting for a new place for over 75 years ago. It's old home was underneath Arizona stadium, a smaller and darker place.
The new building has double the space and plenty of windows to let in the sun. Even the design of the building itself is symbolic. The upper floors are wider than the floor beneath to look like a tree canopy.
The new lab lets the scientists and students show off what their work is all about. Tree ring research gives insight to historic events.
Each ring dates back years ago, and scientists can learn about fires and droughts even about entire cultures.
Inside on the first floor they have pieces of wood that are 2,000 years old, including a ten foot wide, two ton slab of Sequoia. Upstairs new labs for the researchers to conduct their work.
Tomorrow the lab wants to give the entire community a look, there will be tours, exhibits and activities for the kids. Doors will be open from 10 a.m. to 4 p.m. The new and improved lab is located at 1215 East Lowell Street.
