Dormant volcanos in United States

June 20, 1857 Pigeon Mountain volcano, Georgia  The New York Times
A writer in the Sentinel states that a volcano has lately made its appearance in Pigeon mountain, about ten miles from Augusta. On the 24th, ult., the mountain was violently agitated, and the citizens in the vicinity were aroused and terribly frightened by the commotion. When observing the mountain they were more than ever terrified, for a brilliant light was plainly seen issuing from the summit. The atmosphere soon became strongly impregnated with a disagreeable sulphuric odor. On the following day a thick torrent of smoke and ashes ascended from where this light was previously seen. No blaze has yet been seen to issue from the crater. It had continued up to the 29th ultimo about as above described, emitting smoke and ashes without intermission. The crater is thought to be about 100 yards in diameter. No one has yet ventured near enough to ascertain anything of its general depth. 

Several springs in the vicinity have totally disappeared. Many of the citizens are very much alarmed, and some even are moving out of the valley, through anticipation and fear of a violent eruption. The writer states that the principle of a volcano has for many years been germinating in Pigeon mountain. About ten miles south from where the present appeared, is the crater of an extinguished volcano, which appears to have been in an active state at no very distant period. 

March 18, 1874 ... (March 17) Bald Mountain, North Carolina  The New York Times
KNOXVILLE, Tenn., March 17. -- We have no positive information of the volcanic disturbance reported from Raleigh. It is reported from Ashville as being between that place and Old Fort, and not at the Bald Mountains. The rumbling sounds have been heard and tremors felt frequently during the last two or three weeks for some distance in that vicinity.  

THE REPORTS CONFIRMED.
RALEIGH, N.C., March 17. -- Passengers from the west on this morning's train confirm the reports of the rumbling noises and the general upheaving of the Bald Mountain in Western Carolina. People living on and near the mountain are moving out, and a volcanic eruption is momentarily expected.
