Mammoth City, California...

MAMMOTH CITY HERALD, Mono County, California,  Oct. 4, 1879  Now called Mammoth Lakes, this town sits at 7,880 ft. elevation. Gregory notes that this title began June 25, 1879 and ended some time in 1881. Only one institution has any issues of this title.
Its European history started in 1877 when four prospectors staked a claim on Mineral Hill, south of the current town, along Old Mammoth Road. In 1878, the Mammoth Mining Company was organized to mine Mineral Hill, which caused a gold rush. By the end of 1878, 1500 people settled in the mining camp called Mammoth City. By 1880, the company had shut down, and by 1888, the population declined to less than 10 people.
Obviously many mining-related news items and ads.
Four pages, library stamp in the masthead, very nice condition.
