The town is named for its setting in a bowl-shaped
valley which early gold
miners thought was caused by a volcano. Early-morning
fog rising from the valley floor only reinforced that belief. The area was first designated by Colonel Stevenson's men, who mined Soldiers Gulch in 1849. In 1851 a
post office was established and by April 1852 there were 300 houses. By 1853 the flats and
gulches swarmed with men, and there were 11 stores, six hotels, three bakeries, and three saloons. Hydraulic mining operations, begun in 1855, brought thousands of fortune seekers to form a town of 17 hotels, a library, a theater, and courts of quick justice. During the
Civil War, Volcano's gold served the
Union. The "Volcano Blues" smuggled the
cannon "Old Abe," into the town by hearse, to intimidate rebel sympathizers. The cannon was cast by
Cyrus Alger & Co. in Boston in 1837 and is the first of two 6-pounders made on the same day to be stamped with serial number 4. The other cannon still survives at
Shiloh Battlefield and is called "Shiloh Sam". "Old Abe" was only fired once during the Civil War. The
Confederate faction known as
Knights of the Golden Circle owned many of the Main Street businesses. "Old Abe" was fired down Main Street, causing windows to break in all the shops that had not been warned – the ones sympathetic to the South. Abe is the only cannon of that age in the U.S. still on a 19th-century wooden carriage. The landmark
St. George Hotel is listed on the
National Register of Historic Places. Volcano almost became the
county seat in 1854 and again in 1857, but the newspaper closed in 1857 and afterwards, the town began to decline. Although small, Volcano is a town of many "firsts": • 1854 First
