Hello, I recently took these photos at the University of Wyoming’s geology museum and would like to add them to Mindat, but I am having difficulty finding locality for some of the specimens

I have had the same problem, as I move from collecting mineral specimens to collecting pictures of mineral specimens (it's usually much more affordable). All of those counties are available in Mindat. Also Cokeville (here: Cokeville, Wyoming ). It may take a good deal of research to pin down a particular spot in a county, and you may never get it, but you can still put it at the county level and mention the locality shown on the description, or just include the label in the picture. To me, doing that is generally preferable to not posting the specimens. I would suggest using some photo editing software to brighten up the shadows in your pictures, these look sort of dark. That's a common problem taking pictures in museum cases.

Hi, I think that before these get added some addition research is needed.


The marcasite ball is interesting. Little Deep Creek is mainly in Natrona County, but its mouth is in Washakie County. Out of curiousity, I wonder if the marcasite is found in both counties.


The barite concretion looks suspicously like others I've seen from elsewhere in the US. It could very well be from where the label says, but so far I haven't found mention of these in literature. It would be nice if we could have a reference for this.


I might be a little too picky but I think the last one could have been labelled better. Collophane and phosphorite are two different things, so it would have been nice if the label was clearer as to what the specimen is. Also, see http://wsgs.wyo.gov/products/wsgs-2015-ri-68.pdf for a little more on Wyoming phosphates.

Kevin I understand your concern, but I think the only thing I could try is contact the geology department there due these photos being from a month old trip to Wyoming where I visited the college for personal reasons and to visit the museum and there are no other photos of these specimens to be found.

Similar barite nodules to "picture number 2" can be collected from the Pierre Shale (Bearpaw Shale in Montana) from recent road construction along US 212, near Alzada,, Montana. The same or similar stratigraphic unit is widespread in Wyoming. Tom

It's good to get confirmation that the barite-bearing layer is widespread. I've seen similar from Utah, Colorado and Oklahoma.

It's difficult to see from the third picture above, but the phosphate nodules, as in this Mindat photo, https://www.mindat.org/photo-505340.html, are common from a particular Lower Cretaceous sedimentary unit in Montana and Wyoming - I don't have a reference handy, but they are numerous. The locality given for the nodule in this gallery photo really has nothing to do with the Beartooth Mountains. The noodles are found in the shale unit which border the mountainous uplift. They can be found at the mouth of Clarks Fork Canyon, 32 miles north of Cody, Wyoming, and in the same shale unit about 30 miles south of Billings, Montana, below the south flank of the Pryor Mountains.

There's a popular Czech "Encyclopedia of Minerals" - I don't have it handy for a reference, but it pictures identical phosphate nodules from a Czech locality.

I've added pages for the first two.

Little Deep Creek: https://www.mindat.org/loc-303623.html

Bates Hole: https://www.mindat.org/loc-303624.html


Two pages already exist that mention Cokeville: https://www.mindat.org/loc-171846.html and https://www.mindat.org/loc-173755.html

It would be best to contact the geology department and ask if one of these is where the specimen is from, or if it's from a different locality near Cokeville.

Thank you all for the help so far. Here is another specimen that I think needs page for unless the mine is under another name in mindat

I haven't been able to find any information on this mine. The only reference I could find on activity in the area notes two prospects near Merle Creek in THIS PUBLICATION.


You may want to contact the geology department about this one to see if they have any more information. Also, regarding the Cokeville specimen, seek verification if it's collophane, or if it's phosphorite that contains collophane.

Merle Creek flows approximately three miles from an elevation over 11,000 feet to to 8600 feet where it joins Crazy Woman Creek. I believe all of the rocks in that area are Precambrian granite gneiss. The two "prospects" noted in the USGS Bulletin are located in the NE 1/4, Section 25, Township 49 North, Range 85 West, and NW 1/4, Section 30, Township 49 North, Range 84 West. One consisted of a trench 30 feet long and ten feet deep. Samples from the locality showed no economic mineralization.
