How did Etna get its name?
Originally named Rough and Ready, it was changed by statute in 1874 to Etna after the local flour mill (spelled Ætna/Aetna after Mount Ætna in Sicily).
The town began in 1853 as the rough-and-tumble Gold Rush settlement of Rough and Ready, which was later incorporated as the City of Etna in 1878.
In 1854 a flour mill was built a mile away and named the Aetna Mills. However, the winter of 1861-62 it was destroyed by a flood and the remaining businesses moved to Rough and Ready Mill near the current town. This also including the post office which kept the name Aetna Mills.
