Cover art for Rosyln lyrics by Bon Iver & St. Vincent

Shale is, actually, a word; it's a type of rock. But I believe you are more correct that it is "share, scream your worry for what you won't ever find." I also think it's "Down, sit around, folds in the gown," and at the very end it's "We'll" not "Will"

This is such an amazing song. It makes me feel sick that many Twilight fans don't appreciate this soundtrack. What beautiful, beautiful music. Justin did it again.

shale can also mean a shell or to take the shell off something etc
