Good question. This was back in 2009 so I can't quite remember for sure anymore. The National Geographic October 2009 issue is the original source for this, but I couldn't find a copy online. The photographer Michael Nichols posted this article about his experience: https://www.huffpost.com/entry/burden-of-dreams-in-the-r_b_789900 https://www.huffpost.com/entry/burden-of-dreams-in-the-r_b_7... Steve Sillett is the scientist who discovered and measured Hyperion, so I BELIEVE that is the same tree Michael is talking about finally getting permission to photograph. Sorry, I don't know for 100% sure.
