Run fat boy run ;) Great vid this makes me want to return to the states and see the wonderful scenery. the last time i visited i drove through the smoky mountains, it was breath taking.
Its to bad you did not get a chance to film the lava tubes south of bend. I love that place one of the best places to camp I think you can see ever star out there.
Can someone explain to me how the cooling speed of lava can be so wildly different? How does hot rock cool 'rapidly' when the surface temperature of the earth is relatively even. Are we saying that it was a cold day, or that it was rained on or something? Doesn't sound hugely plausible to me...
It could mean colder air, or that it was running into water.. anything that could accelerate the energy transfer from the lava to the surrounding environment.
Cooling won't just happen at the surface. It begins from when magma leaves the mantle.
For example that found at Devils peak never quite made it to the surface and so consequently cooled more slowly and allowed for larger patterns to form. If you look closely, you'll see larger crystals within the rock too.
Lava varies widely in composition from highly viscous rhyolite to very runny, basaltic flows because different minerals crystalise out at different temperatures.
oh, that's plausible. So if the lava makes it from the mantle to the surface quickly obsidian can form, but if it travels through the crust more slowly it cools more slowly.
Only a tiny fraction of igneous rock was magma that made it to the surface without crystalising. If it spends a lot of time close to it's melting point the first minerals to crystalise out have a lot of time to find similar others to bond with so you get bigger crystals.
The more acidic chemicals have a lower melting temperature so the slower magma rises the more acidic it will become relative to it starting composition.
Nice.

Wasn't obsidian the material Hunter&Gatherers used for knifes and speartips?

Having watched all of these "road trip" videos of yours made me want to do something similar.
Too bad Finland doesn't have any really cool sights or interesting geology. It'just... trees, trees and more trees.

I don't like the cold air idea. I mean, lava is 1000C, cold air v hot air is only only 40 degree C difference at most. It doesn't seem significant.

And it depends on the rock type. some cool faster than the others.
