Is the Devils Tower a volcanic plug? The National Park Service of the U.S. Department of the Interior wrote here:
Other theories have suggested that Devils Tower is a volcanic plug or that it is the neck of an extinct volcano (an unlikely theory, for there is no evidence of volcanic activity - volcanic ash, lava flows, or volcanic debris - anywhere in the surrounding countryside)!

I couldn't figure out the formatting used by the editor, and so could not fix them.
"Sigiriya, or the Lion's Rock or the Lion's Mountain, is a hardened magma volcanic plug formed from an extinct and long-eroded volcano."
I've seen this being repeated on several places in the internet, but there is no primary source to back up this claim. For example this paper on the geology of Sri Lankan archaeological sites (including a section on Sigiriya) does not mention an extinct volcano or a volcanic plug.

I notice there has been some back-and-forth editing on whether to include The Nut, a geologic feature of Tasmania, as an example of a volcanic plug. In hopes of settling the issue: This presumptively reliable source identifies The Nut as a laccolith, not a plug.
