Can you help make this a better article? What good localities have we missed? Can you supply pictures of better specimens than those we show here? Can you give us more and better information about the specimens from these localities? Can you supply better geological or historical information on these localities?

Henderson Mine: [www.mindat.org]

Yes, Peter thanks. The Henderson mine is so far the best place for good cubanite crystals and of course high on the list of localities we will want to talk about. Rock

Rock,

Sorry for the delay in starting this. I have been kind of busy lately and when I went to start, I realized that before I can start, I need to put the photo's into mindat.org. Before I do that I've got to put in the localities with references. THEN I need to figure out how to do the article. A little daunting. I need to do it in bite-sized chunks. First the localities....

Dave, You have the idea. I start by looking at all the images I have to work with, my own slides and on the net. I go through the mindat galleries and using paste and cut copy the locality strings of the localities I want to include and put them in a notepad field and then use cut and paste to select the images in the galleries I want to use and paste them in under the localities. Then I review some of the common mineralogical texts and amateur literature. The 25 year index of the Mineralogical Record gets heavily used. Then I write up the text for the general mineral and as much text as I can about the specimens from the various localities. A lot of them I know next to nothing about, and I have to display my ignorance and ask for help. I arrange them alphabetically by country, state etc. I use reverse Mindat locality strings and think we should stick with that. When you have the text in place and arranged with the appropriate headers for each locality, then go ahead and stick in the pictures. If you do your work on line here, you will have many many edits, but at the work progresses you will find people chipping in and giving you suggestions, some of which you will wonder why in the world you didn't think of that and though it often distracts you from what you are concentrating on, it does in the end make for a stronger and better article with a wider perspective. Often people will look at some of the images you are using and think, my god there are so much better specimens than that, and will offer to take good pictures of their better specimens and upload them for you to use also. Sticking in the images is just something you will have to learn. It is not big deal and adjusting their size and placement is a bit of an art, but if you have problems just ask for help.

At the Rochester Symposium this past weekend, Dr. George Robinson showed pictures of a very nice new find of cubanites from Presque Isle park in Marquette, Michigan, from calcite boulders on the shore of Lake Superior, usually underwater, but temporarily exposed last year by unusually low lake levels. The habit is the same as those from Canada, but Michigan's are smaller - less than 1cm.

Can we get some pictures? What is the extent of the find? What does the best one look like etc. Are they etched out of calcite?

Rock,

I have been in contact with the fellow who found them and will contact him for photo and details, eventually.

I did the microphotography for the collector and can supply photos. One has already been posted on Mindat for
a while- a tiny but lovely twin. The best one is a trilling, also irridescent. All are only a few millimeters or smaller,
but very pretty. To whom shall I send the photos, and what resolution would you like for the project?

Sincerely
John Jaszczak
