Cloud Chamber for the Trees and Sky, an interactive sculpture that functions as a camera obscura, is one of the NCMA's most popular works. It's one of two Cloud Chambers in the US and one of only 16 created worldwide by artist Chris Drury. This work is so unique that it has received media coverage and visitors from around the globe. Now, it's being featured in a new book! @AtlasObscura's "America Obscura: An Explorer’s Guide to the Hidden Wonders of the United States" takes readers on a trip to the country's most surprising, wondrous locations, including right here in the Museum Park - and you can pick up a copy later this season in the Museum Store!
