i am not 100% sure of the geography, but how did sudbury material get to yourneighborhood?

Sudbury is only 158 miles across Lake Huron as the crow flies! The estimated area of debris thrown out from this event covered over 500 miles radius. Hard to imagine everything at ground zero being evaporated, stuff just a little farther away being melted, and stuff being thown that far. Ash would have been everywhere, and they have found a special type of carbon, buckyball fullerene, is present in Sudbury impactites. The name buckyball fullerene is taken after Buckminster fuller and his geodesic domes... cracks me up. Being only 150 odd miles from the impact site, if stuff was not strewn all over here, certainly the glaciers coming from the northeast and leaving all the moraines and making all the karsts which mark this area (on top of late Devonian limestone formations)would have dragged impactite along with them. We have gowganda formation and all the puddingstone we have here is brought by glaciers from Canadian mountain formations as well, so why not impactites? (rhetorical)

Yes, I made a mistake on that one. Sorry.

Somehow I had the idea that particular impact was less than 200 years ago. No glaciers in that time span!

I was shocked when I read about it and how old and vast it is, I had been reading up on the geology of the area and never a thing mentioned about this... chance find on a page and have been scrambling like the rug was pulled out from under me ever since (and you know I was on shaky ground to begin with!) Really, who would have thought about meteor impactites??? I feel like the clutch has gone out of the vehicle I have been driving and here I sit stomping on the pedal trying to figure out what's going on. As if things aren't confusing enough already. "Thanks for hanging with me" to everybody on the board. I appreciate your patience and persistence in helping me learn.

I think the reason you feel your clutch has gone out is because you are following a branch in the road with a veritable dead end. Most of what you find is going to be common stuff. That is why they call it common.

St Louis has some great stuff to find in that area... We lived for a few years in southern IL right across from StL, Fossils (especially mammoth-or was it Mastadon? ) just south of you, arrowheads in farm fields (check around Mascoutah, arrowsmith and Belleville IL, think about the regions near Cahokia mounds, look for geodes, Look across the river a little farther south in IL where the glaciers did not go, oh, and the river will have lots of rocky places, especially where the streams feed into it. Nice thing is we all have good stuff in our areas and there are flat rate boxes available for trades! : ) snowmom, I live in Illinois 16 miles east of St Louis in Troy, IL. When I was younger the Cahokia Mounds were literally in my back yard and a neighbor owns a field just south of the interstate and a hair west of the Mounds. Prime hunting ground. I remember seeing all kinds of cool stuff he found. My uncle still lives in that house. Still go down there at least once a month. Love driving by the mounds. Right before dark you can see over a hundred deer come out of the woods all spaced out. There are big sand bars along the St Louis riverside. They have a nice spot where sightseers go and walk around. I think its the exposed sandbar on the Mississippi River. Pretty cool spot. Also there is an old bridge there that you can walk across. Around now its good spot to watch the eagles catch fish. Got an aunt and uncle that live on the outskirts of Mascoutah.

shotgunner, most certainly it is common,nothing could be more common than a black rock, those super dense black rocks interest me a lot. Finding onaping glass from that ancient meteor is interesting. The ancient meteor was the size of a mountain, and they have been mining the impact site since the 1800's with no sign of letup. that means the stuff it left and created is common as anything. But it changed the geography and geology for most of this area for miles around, some scientists even think it planted and stimulated LIFE on this planet. I never said it was diamonds, just tried to say that it is interesting as hell and the changing gears reference was an attempt to tell how much difference it makes in rock hunting to have knowledge of the area you hunt. JamesP, 1Dave, and others have shown me the value of knowing the history of the area you hunt, and I have been trying to express the changing of my own perspective. It is about the information and the learning, not about the materials. bhiatt, we lived in Mascoutah for almost 3 years, and I loved the area. We never went to the Cahokia mounds though they were right there. They were in the process of revamping all the displays during the time we lived there and repatriating the remains of the native people rather than leaving them on display. It was a massive project and there was very little available to the public for several years. I understand it is really great now, but alas, we will probably never pass that way again. Loved St Louis and all its resources, loved the zoos and the museums and the ball games! Just south of Mascoutah I worked for some people at Freeburg, and they had deer in their hay fields all winter, so many I could not count them. When we rode the horses on the trails, they hardly noticed us. It was a great 3 years with so many wonderful memories! Thanks for the nostalgia trip! PS Is that wonderful old stone barn on the west side of the highway there at Troy still standing? I loved that thing! I never got a picture of it...

PS. yes, almost everything around here is common rock, mostly limestone and shale, some chert, loads of granites...lots of incomplete fossils. In every couple million common rocks I come across something different. Because I am so new to rock hunting I get excited about the different ones and want to learn about them. lets end this thread. thank you all.
