Historically Colorado jasper was used exstensively by the native american indians as knapping material.
Found in a wide variety of colors around the state. Recent finds from Park county Colorado Nice piece with vibrant color! Red and yellow pieces. -------------------- CP-Owner/Administrator

Jasper is fun stuff, thats for sure. Im working on knaping a few pieces into looking like fall colored leaves.
We also have a batch in the tumbler right now...Just a few days to go until done. -------------------- Education is the key to the future,

Lots of people think of Jasper Colorado when mentioning Colorados Jasper,
so I thought I would put a link in to their website. What an amazingly beautiful place tucked away here in Colorado! -------------------- Education is the key to the future,

Im not sure, the township was bought by a developer and all private.
Lots of forest service land in the surrounding area though. -------------------- Education is the key to the future,

Recent finds from Park county Colorado Nice piece with vibrant color! Red and yellow pieces. OOoooooooo. I'm so jealous! Wish I could find Jasper like that here for knapping... Any chance you'd tell me off forum where you collected all that? A couple buckets would probably be worth it to me to drive up from Albuquerque. Does it need heat treatment at all for knapping? Thanks, Phil |

That particular batch was from southwestern park county off of trout creek pass a ways. There are some private parcels out that way as well as a state owned wilderness area so watch where you trek as you want to make sure you are still on the FS land. Really nice scenery in that area too!
Not sure on the heat treatment as I've not done any knapping. As I understand from reading, the heating was used to make larger pieces flake into desirable preforms? You may find some that are large enough to need that but most of what's pictured is small already. It sure looks like it would do very nicely for knapping and it takes a nice polish in the tumbler, good and solid. CP -------------------- CP-Owner/Administrator

Really nice scenery in that area too! Thanks. That kinda leave it a little too vague to drive hundreds of miles to try and collect.. If you ever decide to share a little more specific details, you can always email me off-forum if you don't want the world to know (totally understandable) Not sure on the heat treatment as I've not done any knapping.

You may find some that are large enough to need that but most of what's pictured is small already. It sure looks like it would do very nicely for knapping and it takes a nice polish in the tumbler, good and solid. CP Some or maybe most jaspers need the heating to make the material more lithic and thus knappable. Not all jasper is knappable even if heated. That is pretty stuf and would make for some really nice points, even if they are small "bird" points (A misnomer if ever there was one). Thanks again, Phil |

If you ever decide to share a little more specific details, you can always email me off-forum if you don't want the world to know (totally understandable) Actually we have been doing some research in this area and when final details are completed, it will be added as one of the new club members researched prospecting areas with all the specifics. I bet there are quite a few club members who might want to cab some of this stuff too. CP -------------------- CP-Owner/Administrator

Hello Mr. and Mrs. CP. I'm a recent member of the prospector's club. I joined with Swizz. Gold was our passion but it has switched to rockhounding for me. I have many questions regarding this topic but for now I'd like to know about jasper. Can you tell me when someone considers a rock jasper or chert? I've collected many rocks that I thought were jasper but I've been told they were chert. And what about flint? All I see listed for Colorado is Jasper, not chert and not flint. Is there a difference in the eye of the collector, gem maker, slab specimen, etc. Thanks so much for your help, especially with newbie questions.

Hi GB and welcome, make yourself right at home in the forums. We are all very glad to have you aboard.
Firstly, I can not be held responsible for the worsening "rock fever" you will be enduring from now on. All I can say is, start collecting up buckets now, you'll need a head start. Q's will keep coming up too and we all love em', keep em' coming. We have a thread going that has some great info on the cherts and flints in the quartz sub varieties. That thread is titled "Mineral Id'ing" in the prospectors discussions section. Basically chert and flint are both rocks (not minerals) and they are catagorized in the quartz family sub varieties. Flint is described as granular cryptocrystalline variety of quartz and chert also a cryptocrystalline variety. There are both found in similar situations to form but slightly different environments (still trying to figure that part out myself) sedimentary formations such as limestone, chalk, and rhyolites can host them. Both chert and flint are opaque too where as chalcedonys and agates will be translucent. Flint is generally viewed as darker colored and chert being lighter in color.....usually, but not always. Chert also is known to have alot of fossils from algea, bacteria and micro organisms. Now, jasper also being a sub of quartz is described as a dense, opaque, microcrystalline variety of quartz, usually red, brown or yellow. Whew, there is alot of info on these. You can check out more on this from Mindat's quartz page, scroll down to varieties to find links to jasper, chert, and flint. Awesome database Mindat has, just great for learning the details of stuff like this. Lets see some pics of all the cool stuff soon too. Hope we didn't make the "rock fever" too much worse today.

Fantastic pieces GB!
I found a piece just the other day that looked like the little black one in your last pic. Im thinking that one is a flint because of its color, but Im learning too. Thanks for sharing the pictures. Good luck out there, and stay safe! -------------------- Education is the key to the future,
