This is a compilation of some further reading on James Turrell following my presentation on his works today. The skyspace in Philaldephia that Chris mentioned is called Chestnut Hill SkySpace, and you can read about it here.
Beyond his famed SkySpaces, Dark Rooms, and the Roden crater, he has also made some interesting works like a private pool installation called Baker Pool.
Also, if you are interested in learning more about Roden Crater or just the great variety of work he has made, you should see his website and the page dedicated to the crater.
