Could this possibly be a dual meteor crater?

I was doing some glacial research and came across this location. It looks like a nice size meteorite split into two and landed just over a mile apart (1.25 miles). I find it hard to believe that this is erosion from drainage or glacial advance. This area is just on the edge of where the wisconson glacier stopped. So, most hard evidence would be buried under tens of feet of sediment at the LEAST.

The larger crater is about a mile and a half in diameter, and the smaller crater is about 1 mile in diameter.

Here is the location on g earth 40.8343974,-80.4154834

There are 2 central uplifts in each of the craters; however, the larger crater's 'center' uplift insn't on center. Could this be because there was a second collision with the earth so the uplift was somewhat averaged between the 2 shocks? Or perhaps the angle the meteorite came down was pretty great so the uplift wld b further back from center? It seems as if one side is built up larger and the other smaller/eroded away to support the angle hypothesis.

IDK maybe I'm crazy, tell me what you guys think! If you can't find it just type in new galilee, pa into google earth and turn on the terrain feature!

You would probably need "boots on the ground". A meteor impacts ejects material from the crater, a caldera collapses into itself.
Mounding can be weathered away on a crater, see for example lake Mien and Siljan in Sweden. Both (kinda) well known craters, both lakes.

Besides that, the impact from a meteor alters the rock, which also can leave signs to differentiate it from a caldera.

Yes, I was more thinking about ID from an areal view like Google Earth. Like you said a visit might be necessary.
Valle Grande is near my home and there was discussion back a ways if it was a caldera or a meteorite/asteroid impact.
Eventually it was determined to be a caldera. It's huge and even after all this time the trees have not returned.
13 miles across.
It now has monument status so can be visited. I hear the fishing is great and a fisherperson is allotted a stretch of river for themselves for the day.

How do you tell the difference between a crater and a caldera?
Isn't a mounding necessary for a crater?

So what you're saying hvacker, is that you think it is most likely one of the two? Not many other ways to explain it, huh?

This may be a good time to show you guys something I found about 15 miles from there

I think it could be a variety of tektite...here is another 1

Not my area so I'm not sure. If the mounding was still there like the AZ meteorite it might be more evidence. The moon for example as there is no air/water to make evidence disappear.
Interesting approach as most research seems to start from the ground. In a smooth surface from an areal view it seems a dent might show up.
It might need to be more rocky than soil. Soil fills in at least in my yard.

The only tektite I have is from the Trinity Site where the first atom bomb was tested. It is green glassy rock.
Man made sort of.

Mine is green and glassy and very smooth but yet it has a lot of air bubbles and indents...the 1 piece seems oriented and almost has sand grains in it little white dots. it doesn't look like a smelt product to me. never seen oriented slag...the other 1 is a lot darker, still just as smooth, but not very showey.

Doesn't look like weather is permitting this weekend, so maybe I'll just have to go have a look a day after work next week :\

Yeah, no I don't think you can positively ID a meteor crater from aerial-/satellite images.
I've visited one of them in Sweden, a pre-glacial crater, you'd never guess a crater other then if you're a geology nerd with some luck.
Luck as in, finding material relating to the impact. The ice age really ground of a lot of rock.

Collect more "evidence", then go get it assessed by a professional. I've seen slag look like this, though.
But it'd be hard to ID it either way for me, since I never dealt with impactites.

Thats what I've been bugging you for all of this time, eu! You are a pro! You are very good and I appreciate you always helpin me out, shiney or bust! But, yes, if I can go to the site and find 1 more clue, I will seek professional help. I have a few things in mind to be looking for now and I have recently acquired permission to dig and pan in a prime location for this purpose and canadian glacial diamonds! Wish me luck!....:..':cross:

I've been thinking and not all of what I'm seeing makes senses even to me, so I have an alternate theory now. What if a meteorite slammed into the ice sheet, creating a circular devastation of ice slurry, which gave favor for the water to erode out these circular shapes? The water would surely skirt the edge of the glacier. That is how eskers, kettles, etc are formed.

I've seen very accurate GPS equipment that can measure even slight differences in distance. Mostly used by surveyors..
I got to wonder if something like that could be used to find these dents and is the equipment good at measuring slight elevation or possible impacts. Maybe someone is already doing this.
Ya, good luck Rific. Sounds like an excellent adventure. You have my address on where to send the diamonds.

I think you're on to something with the melting of glaciers. Actual geology of local sediments and rock would impact erosional patterns, though.
My bet is still on old lake beds. :coffee2:

Haha how about i send you this chance tektite and u tell me what you think! Equipment for me is pretty limited, ill just have to do a lot of digging. I plan on digging to bedrock in order to inspect for shattercones or impact mineral replacement.

EDIT: Does anyone know big of a meteorite has to be in order to create shattercones or impact melt breccia? The larger crater is arnd 1.25-1.5 miles in diameter, or almost 5 miles in circumference.

Thanks! Impact aside, would you use a sirooka or weva its called to look for the diamonds? I think panning would be slow and the amount of gold i would be getting i could do without. If not a sirooka, what method wld u suggest to look for diamonds in a creek or just dug from the ground?

For a site with just prospects of diamonds, I'd be inclined to bring my batea. But a saruca would be the more dedicated go-to tool I guess.
Never cared for diamonds. They're good for grinding media, that's it.:tongue3:

I didnt know what one was but now i do! The heavies stay in the center so I could just whisk a bunch of material in it, maneuver the pan, the skim off the top, and check the very bottom of the pan? Thank you! Now I'm just gonna have to try n figure out how to make one..dont think they sell those anywhere

I like diamonds all on their own but for one to make its journey through this universe and into my hand would be sensational! I would like to find one so as to earn my right of being a prospector. So far all I have is some specks of gold and a lepidodendrale fossil which almost fell onto my lap. Plus, I can show the people who call me silly there are treasures to be found and yes, there are diamonds in PA!

The batea? Can carve one out of wood, I suppose?
I've heard they're hard to get by in the US. Sold in Canada, though.

Here's how one would use it:


If done slow enough, you will see as garnets and the likes start to appear.

The saruca is easier. It's basically a screen with the bottom mesh having a little give.
