Greetings Chet,
Located a very questionable locality here:
I have never heard of the Gwin mine 2, nor can I find any references at all in the literature.

Perhaps you might have something?

Thanks a'million,

I would not feel comfortable deleting an entry without looking under every rock.

Actually it was quite a large hydraulic mine. Researched it on Google. Please check out the revised file. Thanks!!

Jake Harper June 10, 2010 03:14AM
Thanks Chet - I do not know why I did not think to locate these online references - fantastic (my brain just grew!).
My wife and I actually know the Pitto family, but were not aware that they actually owned the Gwin mine!! Your help is so much appreciated.

On an unrelated subject, I recently obtained permission from Wendell Wilson to reproduce portions of the Mineralogical Record article on New Melones California axinite for Mindat:
All of the text is ready for upload, however, I have a few images including a map and a chart displaying paragenetic sequences that will need inclusion. Do I simply upload these images to Mindat for inclusion, or can I use an alternate URL with HTML "image" code to insert the images from my server?

Many thanks in advance,

Please upload the images to mindat - there are various options within the "Other" photo classification that may be appropriate for your images.

External images aren't acceptable here. In 10 years time your server could be dead and the images unavailable when people view your articles, or worse still the domain name could be in the hands of someone else who could replace your images with something malicious.

You got it, Jolyon - will do!

Milestone reached (in a way). I finished up the K's today, meaning that A through R are done. I will start the S's tomorrow. After I finish the outstanding localities which I have on cards, I will be adding the county level references, starting with the southernmost counties (I did San Diego County already) and then go back into these same counties and tidy up the remaining locality files resulting from Dave's bot extraction of the MRDS database. That will get me out of these southernmost counties and out of Scott's hair. The remaining counties will probably be addressed alphabetically in the same manner.

Thats a lot of work. We need ten more like Chet.

Much appreciated, Chet!

First week of May I ventured down to Coulterville for Mariposite. The Icon on the Mindat map is off by a few blocks. The site is on the first curve of CA 132 west of the intersection with CA 49. Long; -120.19810, Lat; 37.70883

I need to take pix as I also found small pyrites along with the quartz and mariposite and pyrite isn't listed here.

First, thanks to Chet and Jake for this effort... I would like to add the following locality for some interesting California Quartz, which I do not think is listed currently.

Would appreciate any guidance as to how to add this locality myself......


Occurs in albite dike, well formed crystals to 3 cm in pockets, all crystals found as floaters with fractured surface "healed" with small terminations.

Location is roadcut on Hwy 49, 1/2 mile south of Bagby Bridge, Mariposa County, California. N37 36.37, W120 8.069. It has been covered up by debris in road clearing activity and is not accessible at present

Thank you for your interest in Mindat and the California project.

You can start by reading the Mindat manual on entering localities. This locale would be entered as:

State highway 49 roadcut, Bagby Bridge, Mariposa Co., California, USA.

Since there is no entry for Bagby Bridge yet you would go to the Mariposa Co. file, select "add sublocality" and then type in "Bagby Bridge" to the left of the main locality name line. Then submit the entry with the "submit" button near the bottom of the page. Next, go to "view locality page" for this new file, select "add sublocality" and repeat the function by typing in "State highway 49 roadcut" to the left on the main locality name line and submit. Now go to "view locality page" again. Enter "A quartz occurrence located 1/2 mile S of Bagby Bridge along highway 49." and the comments about its not being accessible. Enter the geographical coordinates in the appropriate boxes near the bottom and "submit" again.

Select "view locality page" again. Now enter the mineral species by selecting "add minerals" near the top of the page. List the minerals (don't forget the albite) and enter an appropriate reference at the bottom of the page. Select "submit." Now, you can click on each of the 2 species in turn and select "associated minerals" from the row of buttons along the top. Check the boxes to relate each of the 2 species to each other, select "submit" each time. Finally, on the page for the quartz, go to the "comments" box and enter the data: "Occurs in albite dike, well formed crystals to 3 cm in pockets, all crystals found as floaters with fractured surface "healed" with small terminations." Hit "submit" again. You should now be finished. Go to the locality page to proof your data.

Thanks so much for your mentoring, but I regret I may need a bit more. The locality is successfully loaded, but I cant seem to link in the minerals. When I go to the "add minerals" page type in the names, my references, and then hit the "Add/Update box, the minerals are loaded, but dont show up on the locality page. Probably something glaringly obvious that I am missing

Despite my embarrassment, I will greatly appreciate any assistance

I see some locality information has been changed on my Home Page. I have shown photos of some gold specimens from the mine currently named Eagles Nest. However, that is a more recent name, and the actual name of the mine when these specimens were produced, prior to the 1950s was DeMaria/Garbe.

The daughter of the former owners, Dawn DeMaria is a close friend of mine and inherited this gold collection on the death of her mother.

Thanks, Lyla, All photos on Mindat should be entered under the current mine name. We should add older names and alternative names in parentheses after the current name. And of course in your photo caption you can mention the time period when the specimen was collected and what the mine name was then, if you like.

The Eagle's Nest locality description on Mindat currently mentions the De Maria mine as a "sublocality" of the Eagle's Nest deposit. We should probably add this name to the locality heirarchy. And how does "Garbe" fit into this? Same place, different era? Do you happen to know which year the name was changed?

You did good! The only thing missing (and I filled it in for you) was a reference for the occurrence on each mineral page. I entered "collected by Paul Favia" for each. There was no problem with the mineral entries, simply that your level of access requires peer review and approval for the entries to appear. They should be there now. You can check the locality page to see the end product. Congratulations on your initial entry!

Lyla J. Tracy August 17, 2010 02:55PM
Thanks Alfredo,

As I understand the history of the mine, Mr. Garbe was an early partner. I will speak to Dawn regarding the dates.

Is it safe to resume my work on the southern California pegmatite localities?

Chester S. Lemanski, Jr. August 18, 2010 12:38PM

Right now I am on the "T's" alphabetically for the entire state. My intent is to complete the data input from my extraction cards and then go county by county and tidy up the remaining files which Dave's bot program extracted from MRDS. I will do San Diego County first and then I will then do Imperial County, and at that point, I should be out of your hair. Your can make input anytime you wish but there is no guanantee that our paths won't cross. I am moving as fast as I can right now. Thanks for your patience!

Hi Chet,

Thanks for the reply, I'll give you the space you need. No worries.

On another note, and I know it's a can of worms - are we going to be listing mineral springs as valid mineral localities in the db?

Alfredo Petrov August 18, 2010 01:51PM
If a mineral spring deposits any minerals at all (calcite, aragonite, opal, 'sinter", "tufa", whatever) then it could certainly be listed, If it produces nothing but the water, then it would be irrelevant for our purposes.
