From Sinnott Memorial Overlook, Phantom Ship is right smack in the middle of the photo, below Dutton Cliff, and with Kerr Notch behind and to the left of it. Phantom Ship has long been thought to be the remains of a dike, but work a few years ago, linked in this post, seems to suggest it's a set of flows. (I don't know if or where that was ever formally published.) Dated at 400,000 years, it's now recognized as the oldest feature in the caldera.
