Locality type:


It started out as a placer gold operation until the blue heavy sticky stuff made mining difficult (someone later found out that the "bad" stuff was actually extremely rich silver ore). The ore bodies were so wide that the square set method of mining was invented by Philip Deidesheimer of the Ophir mine.
The Comstock was also home base for Samuel Clemens for a number of years (later better known as Mark Twain - American novelist and humorist).

Silver deposit discovered in 1859 and became the impetus to create the Nevada Territory and a few years later the State of Nevada.
