I'm going to retire in June and head up to the badlands for some collecting. Plan on going to the Bob Ingersoll Mine. Has anyone ever been to it? Any tips on what to look for or do?
I haven't been to the Ingersoll in quite awhile. Make sure it is open first.
I parked off the highway by the access road. There used to be space for a car or two at most. Just as you start up the access road just off to the left there were some piles of rock that contained schorl tourmaline. These rocks may have been bulldozed when the accwss road was made.
As you hike up the access road there used to be several exposures of phyllite to fine grained mica schist right in the road bed that contained staurolite crystals. This would be part of the contact metamorpic rock around the pegmatite itself.
In the dumps, check the mica books for green tourmaline crystals usually aligned with the layers. Peel apart the books carefully. In somewhat fine grained massive white feldspar, sprays of a more blueish colored tourmaline can be found. These crystals are not in open pockets but can be quite attractive specimens. I found several of these sprays up to six inches long. There are some unusual minerals there so keep your eyes out for anything that looks different from the bulk material. If you are not an experienced mineralogist, hang on to the stuff until you can find out what it is.
Al and Joe thanks for the info. I printed out the maps of the mine. The latest info I can find on the mine is that it is abandoned and has no no-trespassing signs. The huge mine building is still there and there are 3 mine openings as well as many piles to go through. I really hope people that have been there have not been distructive and it is now posted and off limits. The maine mine was open and was not hard to explore. If it's all this easy, I doubt there is much left to find, but would still be worth the trip. I found 3 or 4 other mines very close that are also abandoned. Don't know about access. If anyone else has any info on the area around Keystone I'd sure like to have it.
Why did I put an "e" on main????
I collected there in 2005 and came home with lots of blue and green tourmaline and a little beryl. Like Al said the greens and blues are in the mica books. I hiked to the top where the shaft is and found some thumb-sized blue tourmalines in the wall. One thing to watch out for is rusty nails. They were all over the dumps, so watch where you step.
While in the Black Hills I also collected at the Dan Patch, the Etta, the White Elephant, the Tip Top, and the Helen Beryl Mines. There was a store in Rapid City called the Dakota Prospector or the Black Hills Prospector or something like that. The proprietor had driving directions to many of the mines in the Black Hills and what you could find there. I'd also recommend checking out the SD School of Mines Museum and picking up a copy of Roberts and Rapp Mineralogy of the Black Hills.
I got to hike up to the shaft of the Ingersoll about 10 years ago with a group of collectors from the Oshkosh area. I had a blast and I too found the blue/green tourmaline. I have a nice amount of specimens from there. The tourmaline that are in the mica books are really striking. I also found a few chunks of lepidolite with the very deep blue tourmaline embedded. I also have specimens of the staurolite in mica schist.
This was a very special trip for me as it was the very first "real" rock collecting I had ever done. I had wonderful, knowledgeable people guiding and helping me. The only times I didn't listen to the experts were when they would tell me something I had in my hand was just a "leverite"...just leave it right there...lol...for a new collector I just couldn't leave some of them behind. Now, I am so glad I did keep those "leverites", they have provided me endless hours of study material and I could pick it apart without feeling like I was destroying valuable specimens.
I hope you have a wonderful trip and find lots of treasures.
Sounds like atleast at one time there was some pieces to find. Hope alittle has been left for me. I'm sure i will come home with several pieces that have been picked up and thrown back down, many many times!!
You mihgt want to contact Tom Loomis at Dakota Matrix Minerals. Several years ago I suggested this to a Germany collector and Tom took the time to show him around. No guarantee he would have the time free when you are on your trip but worth a try.
Thanks Doug, sure can't hurt to try.
From what I hear, the Ingersoll Mine is now off limits. I haven't heard this directly from the owner, but from several locals in the area. Approximately the lower half of the access road crosses private property, and you are NOT permitted to deviate from the roadway. Collecting mineral specimens or anything else in this area is theft! The upper part of the path belongs to the Forest Service, and I don't know what their rules are. Of course the land surrounding the mine is again private property. In each case the boundary lines are difficult to spot. I usually help the landowner of the bottom portion of the trail put up No Trespassing" signs on either side of the road, but the bad guys rip them down almost every year.
Hi everyone, my friend owns the Ingersoll Mine and has to deal with idiots who think it's an abandoned site that is free to the public. Someone beat him up this summer and it needs to stop. As another person stated, trespassers just keep ripping down the "do not trespass signs". How would these tresspasses feel if beligerant folks just wandered onto their homesteads and helped themselves to whatever they wanted? We'd greatly appreciate everyone getting the word out that the Ingersoll Mine is indeed privately held. Mark will allow people to mine for stones for $20. Please get the word out. Thanks everyone!

I, for one, made sure I had permission from the owners. I always do. But, as you correctly attest, there are those who do not and only one is one too many. I am saddened to hear it turned to violence. If the dumps are available for a digging fee would you please post the relevant information here. The folks that regularly post on this board are a fine group that would help make sure the information is out there. Or, have Mark make a posting. Almost all of us here want Mark to see the up side of honest collectors. As to the belly crawling slime that come here just to get information to trespass, I pray they get caught and are prosecuted to the fullest extent of the law. Best Regards, Al O
