Hey Chuck, just drive a few miles west to Aberdeen. I'd be glad to let you see them. Might load ya up with some stuff out of my storage shed too.

Do you know where the origin of those is? Isn't most of the rock in your area either pushed down from Canada or washed in from the west? It is strange (to me anyway) that similar stones are not found in other areas. How big of an area are they found in? Just curious. Sweet new batch by the way. Again I have to say that the grey one is the sweetest.

They originated in the Minnelusa limestone formation. A good portion of the Minnelusa was exposed during the upheaval that created the Black hills. Fairburns are found from the Black Hills as far east as the Missouri River. As far south as Chadron Nebraska, and in a small area of N.E. Wyoming. Nobody knows for sure the exact locations in the Minnelusa that the Fairburns came from. But experts can tell on sight where in the grasslands they were found by the different color variations. I'm not that good yet, but I'm learning.

Ok, I was way wrong on the Black Hills but I will not admit my wrongness. lol So then, does most Fairburns come with an area or location attached or does that not matter?

Actually Jim, you were right and wrong. The Minnelusa formation extends completely through the Black Hills and down into Nebraska. During the cold war when we were searching for new sources of uranium, chips of Fairburn were brought up in core samples from 600' down. Many of the hills agates have the same sort of fortifications, but are different color combinations than those found in Fairburns. So millions of years ago they all formed in the Minnelusa. Erosion and spring floods have eroded the Fairburns out and tumbled them for many miles to the areas where they're collected now.

New arrival on 10/31/2012 2 lb. 6 oz. full face pattern Fairburn. This one will look much better after a nice long, warm acid bath.  |

3 New Fairburns today. Showing both sides of 2 of them. This one just has a thin band of fortifications about 7/8 of the way around the middle. Side 1  Side 2  The next is almost solid agate, with fortification covering over 1/2 of the surface. side 1  Side 2  The last is just a large chip, about small walnut size.  |

2 lb. 6 oz. fairburn after boiling in slightly soapy water for 3 hours. Some cleaning is evident. All lichen has been removed. Some dirt in cracks is gone. Pink color starting to show in some fortification banding. Stone is now in a strong oxalic acid bath for 2 to 3 days, followed with 72 hour soak in water. Water will be changed every 6 to 8 hours.  |

Just an added note. Something I didn't mention before. Of the Fairburns with black banding, a good portion of the black bands are actually heavily tarnished pink, red or orange bands. Sometimes this is exposed by acid cleaning. I'm hoping that at least a few that I'm going to acid clean this winter will show the more colorful natural colors. Hope a couple show the rare orange bands. Those are found in and near the Badlands National Park. The first pic in this thread shows the orange color, and was found just outside of the park to the S.E. about half a mile.

amazing! Soon, South Dakota will have to import rocks. Otherwise, they will all be in your house!  I love it when a person follows their passion, there is no end to the fun. Keep sharing the pictures. |

Two more on 11/15/2012.  It's hard to see the fortifications on the next due to its coloring. It has a small amethyst center.  |

Don-I am almost speechless(and believe me,that takes some doing!)
If I lived another thousand years don't think I could come close to the museum type collections that you have,man,I am just happy to have added a couple of pieces,and to know that thousands upon thousands of people will eventually realise that your collection is something to behold,-as is the obvious joy you get from each and every individual piece-rock on brother!
John.

John, these are hardly museum quality pieces. I have friends who live right in the heart of Fairburn country who do have some museum worthy pieces.
I scored another Fairburn on ebay today. Shoul have it before the weekend.

Hey Don-maybe they are not museum quality to you,but they will be one day-and sure some others might have slightly better,but a couple of years ago I was in a museum in Montrose,Scotland,they had a bunch of local agates on display,and I know that the next time I'm up there,that I can totally surpass anything they have-I know where the real stuff is,and that only comes from putting yourself out there,and talking to those who know;-as I am sure you do,still looking for those beautiful slabs you sent me-especially the Teepee Canyon-that really rocked me-now have a small Robilt flat lap,and that piece in particular sings to me,can't wait to polish it up,all the best my friend,Take care,John.
