Another Beautiful Mystery Flower

Do you know what this flower is?
If you have a guess, let us know!

While hiking north of Elk Garden (between Whitetop & Mt Rogers) along the Appalachian Trail performing a bird survey, a group of us noticed quite a few flower stalks in the forest at about 5000 feet elevation, perhaps 7-10 inches high with a tuft of white flowers at the end. But there were no leaves evident.
I am not familiar with this strange plant and cannot find it in any of my books. It reminds me in some ways of a mountain lily (Clintonia) without leaves, and vaguely resembles book photos of a false asphodel, which I have never seen.
Any help will be appreciated.
