California, USA

Welcome to the California talk forum!

This page is created to provide a forum for Mindat contributors/users with an interest in improving the California state and sub-locality files. All with such an interest are welcome to use it. All manner of issues dealing with the California project are permitted and interaction is encouraged.

I envision this utility as a means of exchanging information and coordinating efforts to avoid conflicts such as two people starting work on the same area without each others knowledge.

Right now I am continuing to add in data extracted from Murdoch & Webb (1966) and Pemberton (1983). I am almost finished with localities beginning with "G." Thereafter I still have "H" to "K" and "S" thru "Z" plus some prolific localities which I have shelved until the end.

Thus far this effort has resulted in the addition of many of the mining district and mountain range files and numerous intermediate locality files (towns and other features). The county files are now complete (we were missing a few). A relatively large number of duplicated files were identified (and are still being found) and consolidated with subsequent editing to merge all data within the combined data fields.

Great to see locality info opened up to comments and your efforts in adding all this info are appreciated, Chet.

Thanks Jim!

Hi Chet,
My small library contains some great references on Calaveras County, CA mines and minerals and I am currently working on descriptions and locality info for:
Gwin mine, Calaveras Co., California, USA

Could you let me know how to go about obtaining Latitude / Longitude for this mine?
Ah... questions from beginners!

Thanks much in advance,

Jake

Jake,

They are: 38°16'33"N, 120°45'29"W - got them, from: [geonames.usgs.gov]

You can also use: [peabody.research.yale.edu]

With this latter site go to the last button down on the right side (GNIS database) and click on it. Fill in the data you want to search for and search. I have these on my favorites list and use them very frequently when I add in the intermediate levels in the locality strings (towns, mountains, etc.). Don't forget that when you enter coordinates into Mindat you have to go back after submitting them and change the longitude from E to W and re-submit or else your North American localities will show up in China!.

Excellent. Thanks a million, Chet!

Hello Chet,
I am currently working on:
Green Mountain mine, Chile Gulch, South of Mokelumne Hill, Mokelumne Hill area, Calaveras Co., California, USA.

However, I did notice there is another entry for this locality that includes Chile Gulch and Rough Diamond crystal mine from "Tuolumne County":
[www.mindat.org]
This is incorrect, as the both the Green Mountain and Rough Diamond are both located in Chile Gulch, South of Mokelumne Hill, Mokelumne Hill area, Calaveras County. (15 mi away, in my back yard)

Jake

Jake,

When you find a duplicate like that and you know what the correct data are, just correct it. In this case, simply delete Tuolumne Co. and replace it with Calaveras Co.

Nice write ups on these localities!

Jake,

I eliminated the 3 duplicated files and edited the combined data to eliminate the stuff from the deleted files. Please have a look at it now and see if it is correct. Thanks!

Chet

Mark Mauthner,

I appreciate you coming online to help with some of the California pegmatite localities.

If you feel that the Oceanview/Elizabeth R. mine area is not accurately reflected on mindat, please consult with me and we can work out a meaningful correction and update together. I know we need to update the text to reflect the Kunzite find and underground progress, etc.

I am excited to see that you are going to help with Chihuahua Valley and possibly the Cooper Canyon area.

Regards,

Scott

Jake,

One of the tasks that I have been working on as I encounter eligible files is adding in "Mother Lode Belt" in the locality strings of all mines and their districts. If you have references providing these data please keep this effort in mind. "Mother Lode Belt" would go to the immediate left of the county name in the strings (i.e., between the district and the county.

Chet,
The clean-up on the "Moke Hill" localities look PERFECT! Very cool that you Merged the Rocks & Minerals reference instead of removing a very valuable resource.

Thanks also for the addition of "Rich Gulch, Poloma" to the Gwin mine locality: I am still unsure how to go about adding those "middle" data to the locality strings as well as what exactly my abilities/restrictions are when editing these localities. I will certainly keep in mind "Mother Lode Belt" when appropriate. There are actually three belts in the "Mother Lode" area:

The East Belt: Mines located in Mesozoic granite and Granodiorite.
The Pocket (central) Belt: Mines located in Calaveras formation and Mesozoic Granitic intrusions.
The Mother Lode Belt: Mines located in Calaveras and Mariposa formation rocks to the west.
From the excellent Mineralogical Record article by Wayne Leicht: Gold occurrences in Tuolumne County, California, Vol. 18 #1, 1987.

Jake

Jake,

You can make the changes. If you don't know how to merge duplicate files yet let me know. Adding in the intermediate steps is rather simple. Usually the nearest town. If it is more than about 3 miles in a more crowded area, or about 10 miles in a wilderness or desert area, I use "area" after the town. I also use "area" if the nearest town/feature is in an adjacent county. Distance and direction help. If there is firm information that the locality is in, on or near a river, in a canyon, on a mountain, then that feature is in the string, before the town name (usually). If something is "near" a mountain, it is obviously not "on" the mountain, so it is also then "area" after the mountain name.

Chet

I was aware of three belts but I haven't educated myself very much on the two others (east & middle). You can add them as required.

Scott,

Can you please take a look at the new In-Ko-Pah Gorge file added by Jolyon?? I corrected the spelling and add in some location relationship data to Ocotillo and Jacumba. Is the gorge within the mountains of the same name (I take it that it is not). Does nthe gorge extend into San Diego County?? If not, should we correct the file to Imperial County? BAsed on your description of the Jacumba District, it extends into Imperial County - correct?? If so we need to make an entry for the district in that county as well and explain that it is an extension of the district from San Diego County. Thanks!

Chet

This was to accommodate an entry from Rruff.

Jolyon,

I am aware of that - we needed the entry, but I am questioning the acuracy of the locale particulars and Scott should know more than I do in this case.

Excellent - was a little worried i'd just dropped some crap in that upset your neat organization, glad you're dealing with it!

Jolyon

Okay, I was wondering why the Jacumba District [www.mindat.org] had become broken. I first noticed the problem when a locality was added called the In-Ko-Pah Mts (In-Ko-Pah Range), San Diego Co., California, USA [www.mindat.org].

By error or omission, the Jacumba District has become both a sublocality of In-Ko-Pah Mts (In-Ko-Pah Range), and a separate top level locality. Based on the existing input, the district has both the In-Ko-Pah mountains and the Jacumba Mountains, as well as many peaks, gorges, canyons, etc.

Chet, If there are no other issues I will fix what we have so far for the Jacumba District and make sense of it all. Is there a consensus on splitting the Jacumba District into two separate sublocalities of both San Diego and Imperial counties?

Jolyon, I can also correct the county and town errors on the new page for In-Ko-Pah Gorge [www.mindat.org].

It's probably historically important to note that the Jacumba District was around prior to Imperial County being created by the splitting of San Diego County. I'll add this information to the district pages, and make the other corrections tonight if there are no objections.

Update: Corrections have been made, can use a few more hours of work for sure, but will likely wait for live cache clearing software update.

Thanks Scott! I really appreciate the assist on this one. If a district is in 2 counties it needs 2 entries unfortunately. When I touched this yesterday I noticed the mess with this area. Unless I find new localities to add, I shouldn't be touching this anymore.
