Originally posted these in the Gold Prospecting Forum, thought I'd come over here and share them for the sake of thoroughness...
As winter settles in and most of us prep for next gold season, some detailed and fascinating old documents may guide the interest of some, and warm the fancy of others more remote.
These are links to the Gold Belt Folios, the original and highly detailed geologic survey maps of the Mother Lode district and gold deposits of the Sierra Nevada range.
Some of the notation will be obvious (hello, Auriferous Tertiary gravels), but other gold-bearing rock formations and their ranges can be deduced from careful reading of the text notes for each folio along with inspection of the maps themselves.
This site has a map showing the locations of each quadrangle and also offers a DVD version, but some of the information they list is slightly inaccurate.
** NOTE: I am not involved or affiliated with either Sharing History or USGS in any way. These links are provided for purely informational purposes only. Use them with your own responsibility.
For the sleuthing gold hound, these are terrific winter reading.
Hope you all enjoy poring over them as much as I do!
