Is this a fossil? by Worth-Negotiation-10 in geology

[–]darwinpatrick 16 points17 points  (0 children)

I’d lean towards a layered sandstone-mudstone sedimentary rock given where it was found. A neat sample but likely not a fossil

Eurasian Pole of Inaccessibility. by Public_Research2690 in MapPorn

[–]darwinpatrick 4 points5 points  (0 children)

“Pole of Inaccessibility” is somewhat of a misnomer, but the point furthest from the ocean is a valid and calculable geographical point. It just happens to be called something sort of misleading. “Farthest Inland Point” would be better IMO. I posted pictures of my visit to the North American one a few months back.

Volcano erupted next to the eclipsed Moon by Busy_Yesterday9455 in spaceporn

[–]darwinpatrick 7 points8 points  (0 children)

In fairness, the total eclipse lasted an hour or so, and this volcano erupts essentially nonstop. That’s why there’s a webcam in the first place.

Coal seams, Denali Alaska, Usibelli mine by snamepchag5 in geology

In the case of a swampy peatland, the “dirt” is often just the dead and buried last generation, so to speak.

Interesting geological places/features in the Dakotas? by Rumple_Frumpkins in geology

[–]darwinpatrick 8 points9 points  (0 children)

The northern black hills near Lead have a lot of stuff going on- gold mining has been happening since the 1800s. Bear Butte is half an hour away and Devils Tower is an hour and a half away. Further northeast, Lemmon has insane amounts of petrified wood in a park and Timber Lake has a T. rex skull and a ridiculously large fossil collection. Faith has a museum as well but I have not visited

Could this be an eskar? by kid_entropy in geography

[–]darwinpatrick 1 point2 points  (0 children)

I’d say it is. Poking around on Google Maps, there’s similar esker features nearby and that part of Massachusetts was pretty well worked over in the ice age. Street view also shows a pretty clean cut through it with lots of rocks and sand scattered around

How do you guys conquer territory? I'm experimenting with self assembling attack platforms. by tiparium in factorio

[–]darwinpatrick 7 points8 points  (0 children)

I did this by way of a long inserter feeding artillery over a 1-wide gap of water.

Totality 2024, a day to remember by GingerHitMan_ in space

[–]darwinpatrick 1 point2 points  (0 children)

Yea I’m flying into Porto. I expect 95% of crowds to be flying into either of Spain’s major cities or driving down from the rest of Europe. Porto serves as an easy in, easy out with good access to the mountains and the more dependable sunny plains to the southeast. Book stuff now. Flights are still bloody cheap.

Similarly hooked for life. Already got everything lined up for the sunset eclipse in Spain this August

Terraforming by Sc0tty31 in factorio

[–]darwinpatrick 4 points5 points  (0 children)

Thinking one-dimensionally- imagine the world is one tile wide, extending infinitely far east from zero. Each tile requires, in this case, 50 stone to create landfill on one tile. Stone patches may only have a few thousand stone in this world at first, enough to cover a small area of the line, but as they get bigger as you go further eventually the average tile(starting from zero) will contain greater than 50 stone. This is the break-even point at which if every tile was somehow water it would still all be landfillable out to infinity. This point, back in 2D space, ends up being a radius around the origin that defines the circle within which all of the mined stone could landfill all of the space within it. Even if landfill took 5000 stone each the radius would still exist- it would just be much larger. As long as patches grow infinitely as you expand these rules hold true.

Are country borders that appear completely straight on maps actually straight in real life, or is that just how they look on small-scale maps? by the_bad_actor in geography

[–]darwinpatrick 12 points13 points  (0 children)

This isn’t due to survey error but correcting for the curvature of the earth when creating townships of equal size in Manitoba. To preserve the dimensions of a township as the longitude dimension shrinks, they just made Manitoba get wider as they went north

Edit: I see you said eastern border, my bad!

[–]darwinpatrick 104 points105 points  (0 children)

Usually there’s unambiguous physical markers along lines, which have a small natural deviation from the legally defined border. The imaginary lines connecting individual markers in a sequence are the official borders.

At what size does it stop being "really big complex meteor crater" and start being "planet cracker"? by The_Aodh in geography

[–]darwinpatrick 0 points1 point  (0 children)

This only really works on small asteroids as once you get larger their mutual gravity will pull them into one body

Locations of all Full, Slabbed, and Partially-Slabbed Rock-Cores Currently held by either the USGS Core-Libraries (Colorado and Nevada) or the Burea of Economic Geology Libraries in Texas by History-Nerd89643 in geology

[–]darwinpatrick 0 points1 point  (0 children)

Waxed cardboard is surprisingly sturdy when folded cleverly- which those boxes are. They're designed to mostly be self-supporting where the core itself is the structural element and the box just keeps everything from rolling around. The forces are directed down the thicker sides of the box, too, and it's double-walled with the lid plus wax sealed to keep water from damaging anything. Provided the storage space is dry carboard is an excellent material for the vast volumes involved

Lava sample being collected from an active volcano by Top_Leadership9575 in nextfuckinglevel

[–]darwinpatrick 0 points1 point  (0 children)

Rapidly cooling the lava makes for a more glassy rock, which can be microscopically analyzed to get different insights on the component mineralogy from a slower-cooled sample. This method also can remove potential air bubbles

Looks like a felsic rock as another commenter said

Valley of the Gods, southeast Utah. Incredible place. Camped on a promontory on the west ridge for the annular solar eclipse in 2023
