The visitors center was built for the crater good

    I'm sorry about that. You don't like Sergeant Brick-Angel?

    I went there, but they wanted to charge like 40 bucks a person to see the crater, so we left.

    I find it incredibly weird that we, as people, respect it when someone says "That crater created by tons of falling space stuff many millions of years ago, is mine! No one can look at it, unless you pay me!". I mean, wtf? How does that make sense? What asswipe sold that crater at some point in history, and what gave them the fucking right?

    Is the (w)hole damn thing surrounded by a fence?

    I'm not sure if it's all fenced but the entire thing (including the road) is on private land, so walking around it is trespassing.

    There's only 1 road going there and it ends at the visitor's center, and impact crater walls are higher than surrounding terrain, so unless you get past the visitor's center all you see is a hill.

    Yes, the entire crater is surrounded by a fence and on private property. It's not worth the admission price just to see a crater imo. It's a national landmark, not a national/state park. Unfortunately that designation means very little other than the owner being eligible for some tax breaks so long as they keep it preserved. I find it insane that such a landmark wouldn't be taken over by the state for preservation.

    That's a long drive to turn around. The museum and visitors center was more interesting than the Crater.

    It was very gusty winds when I visited, so only a brief time outside observing the Crater. There was a large hunk of meteorite inside, an educational lecture, and a museum. It was one of the highlights of my trip but it's not for everyone.

    I recall someone else turning around and saying it was too expensive when I was purchasing my tickets.

    The drive was so gusty that the wind was pushing the car while I was driving it. What a day to remember!

    Imagine working at the visitor center when no one's coming, then one day you have a massive meteor impact and suddenly have something worth visiting in the vicinity of your visitor center

    you could say that their luck has been.. cratered

    So does the rock itself disintegrate on impact or is it under the crater?

    Fun fact a rich guy once bought the mining rights to a meteorite impact crater believing that it would be an easy source of pure iron to mine since most meteorites are primarily iron, but after digging for hundreds of feet and finding no iron the project ran out of money and went bust, because meteorites disintegrate into first a liquid iron, which then oxidised very rapidly and becomes dust and small chunks which settle in an ejecta pattern around the impact zone, sometimes many miles wide, and this thin layer is fairly quickly eroded away, so there's no usable iron nor a meaningful amount of oxide remaining.

    Smaller meteorites often land intact, as their surface area allows for meaningful atmospheric friction to slow them down, and these are chunks of iron, but larger than about the size of a large van, the meteorite is usually obliterated.

    Entry angle can allow for exceptions, IE if a meteorite just grazes the atmosphere but still slows down enough to suborbital speeds, it can land as big chunks, but even these get scattered over hundreds of kilometres. Any impact steeper than about 20 degrees and larger than a large van is usually carrying so much momentum at ground level that it hits at several, and possibly tens of kilometres per second, which liquifies and scatters it widely.

    most meteorites are primarily iron

    I have to note that this is not correct. Chondrites make up the vast majority of meteorites, and even the most iron-rich chondrites contain much less than 50% iron by weight.

    I haven't been to Barringer Crater and I don't know all the sweet, gory details of the big bolide that made it, but LPI seems to have a nice summary. The estimated 30 tons of meteoritic iron retrieved from the site certainly isn't very much, and I have heard a variant of Agent641's story before, so I'll refrain on commenting there.

    I'm a little sad thinking about all that oxidized iron, though. On Luna that stuff gets reduced instead, so that the regolith is peppered with little spheres of iron. Of course, here, we don't get the little balls of iron, or much in the way of intact craters at all... damn it, we could use a few more.

    Sighs Earth. For all the predators and the continent-busting rifts here, this place just isn't very hardcore sometimes.

    I wonder what would happen if a large one came in directly perpendicular to the ground at high speed (for a meteor). Like the atmosphere is really pretty thin and that trajectory would have the least exposure to it.

    It probably wouldn't change the outcome much. Meteorites usually have a relative velocity to earth of 8-50 kilometres per second. At those speeds, it moves much faster than a ballistic missile, and those things haul ass. Whether entering at 25 degrees or 90, it would instantly turn the air to plasma and pass through the troposphere and hit the ground in just a few seconds.

    It's basically like setting of a nuclear explosion at that site. A big one, getting close to the Tsar Bomba. Everything nearby including the meteor turns to plasma and vapor, and that creates a shockwave that blows out everything nearby not instantly vaporized.

    Thanks for the big circle. Otherwise no one would get the joke.

    if the center was there, the impact wouldve still obliterated the buildings.

    Yeah but now that poor visitor center is ruined. People went there to see the vast open desert, not some hole made by space garbage! I hope the government can bail them out

    Okay jokes aside was it even desert when the impact happened? Like I know of an impact in Germany that happened so long ago that Germany was a jungle.

    I don't know when that crater happened but not far from it is the petrified forest. Which if you don't know is from trees falling into swamp water/mud and basically becoming rock. So at one point that area was a jungle/swamp as well.

    Yeah I was aware, just haven't looked into into the local prehistoric environments of Arizona once the interior seaway ceased then there's a gap until the last epoch give or take. Fun fact the original spreader species for avocados was a species of giant ground sloth.

    Anyways it was just idle wondering from me, I find the history of local environmental conditions interesting. For example densely forested Crete or Scotland during early historical accounts but not within any modern periods.

    Obviously the meteor was finely tuned to avoid hitting the visitor center
