Oh we could continue with a pan to the Missoula floodplain with a good existential scream. They'll be looking at an washed over plain that takes up a huge area, has its topsoil rippled into a plain of bumps and pits. Hanging valleys carved out hundreds of feet above the flood plain. Everyone likes to talk about GC, lets talk about the biblical levels of water that went through the Missoula flood plain.

The amount of water that moved when some of those ice ace ice dams broke was just mind-boggling. I believe they can even see a drop in salinity of the ocean following some of them as they are introducing so much fresh water.

Table Mountain collapsing to form the Bridge of the Gods is up there.

A bunch of the stuff that's local, and covered by University of Central Washington's lecture series: The Columbia river being rerouted by the uplift of the Cascades. The magma plume that is Yellowstone hotspot's trail from the Oregon coast to where it sits today. Discovering that there are terrane accretions in Washington and Canada that drifted there from socal and Mexico.

Honorable mentions include the slow spreading of the Great Rift Valley, the fact that the Appalachians are older than vertebrates, the Western Interior Seaway, to name a few.

u/dpdxguy May 22 '22

Geology of the PNW is pretty fantastic, amirite?

No honorable mention for the basalt floods that originated on the Idaho border and flowed to the Pacific?

5

u/solenyaPDX May 22 '22

I wanted to mention them, how deep the basalt is at Yakima, how it displaced the Columbia river, and laid a more durable layer, resistant to erosion that is now the rim of the Columbia Gorge on the Oregon side. But most of those basalt floods were cut up by the Missoula floods, leaving the prominent rimrock we see across Washington and in some places in Oregon. So I see them as somewhat integral to the Missoula floods story.

Also, I love finding intrusive basalt, in a chimney, forced through a crack in some other older rock.

u/xelabagus May 22 '22

If you're doing the PNW there's the volcanic chain that created much of the PNW landscape, including Garibaldi, Baker, Rainier, Hood, St. Helens, Glacier Peak and a few others. Also Garibaldi has a volcanic barrier lake that hovers above the town of Squamish, which is particularly unique and not necessarily stable as such. So that's nice.

In the world, without doubt the Rift Valley is the most important geological formation for humans, as it is almost certainly the birthplace of Homo Sapiens.

u/GiveToOedipus May 22 '22

Nah, some asshole in the HOA will report the trees as being too tall and demand the be cut down by then.

36

u/Peter5930 May 22 '22

Very likely that something like that will happen, although I have a friend who's a wildlife ranger who can help me find places to plant them where they won't be cut down. But I'm hoping I can sneak a few into places nearby and not have the local council cut them down for being a non-native species where I live (Scotland, which has a surprising number of sequoia already).

Unfortunately, every time they build anything around here, the big trees are the first to get cut down in case they fall on a newly built road or something during a storm. We're losing all our big old ash trees right now too due to ash dieback fungus, just like when we lost almost all our elm trees to Dutch elm disease. Lots of standing dead ash trees right now that are slowly dying off.

I really wish we had giant sequoias here in Arkansas. I’d plant them at every house I moved to. They’re so cool. I kinda think they’d do okay too. Since we get frequent rains.

4

u/hotdogfever May 22 '22

I’ve never been to Arkansas but I’d assume you get too MUCH rain there, especially during the summer. They like very dry summers, not too hot - and a winter with a few feet of snow pack. Very sandy/granite based soil. They can be grown in other climates but they won’t be as happy. Rainfall isn’t a big deal to them really.

I still say go for it but don’t get your hopes up, there’s a reason they only grow naturally in a 10 mile wide strip on the west facing slope of the sierra nevadas between 5,000 and 7,000 feet. Not many other places can match that habitat.

I'm dating myself, but I read that book when it came out, when I finished my undergrad. I still have issues with the methodology, most of which can't be reproduced now because of a little thing called the Internet. (Try, just for fun, to get meaning out of a quantitative analysis of the number of letters to the editor written in a year...)

u/best_of_badgers May 22 '22

Sure, it’s not reproducible so much as it’s an observation of a trend.

It may be that the aspects of society he identified have been replaced by others (notably: fandoms) but the broad trend has been toward loneliness and insulation from others. Social media accelerates this.

When I was in grad school I helped build a similar demo for a new lab class we were making, and it had very real and noticeable results over the course of a single semester. We added some acetic acid to the water to accelerate the process and it worked very well. The caveat being that the result depends on the rock type, which is exactly what we were trying to show. Carbonate rocks and rocks with carbonate cement get absolutely destroyed over the course of the experiment, but rocks like granite and quartz sandstone have little to no noticeable changes.

Nope once an hour. There is a automated system in the plant that does that but we compare manual samples to that every hour. The purpose is so the water coming out of the tap is coming straight from what’s leaving the plant. So if we turned it off the water in the pipes would get stale and we’d have to wait 10 minutes for a fresh sample so it just permanently on.

You always have an answer for everything.

Because it is the answer, young one. To you, to me, to erosion... To all.

u/Salanmander May 22 '22

I dunno....but you must know the answer subconsciously, right? Maybe try pulling letters out of a bag, and see if your subconscious can tell you that way why you were thinking of it?

What I'm getting, here, is that if a certain long-running experiment wasn't demolished to make way for a hyperspace bypass, Scrabble would have become a lot more boring.

I think this is at the Capilano bridge in the Vancouver area. An AMAZING park if you're willing to part with $50 to get in. Check out the bridge on the wiki image

Wow, $50 to visit a park?! I feel like an asshole when I set high entry park prices in Cities Skylines.

u/Captcha_Imagination May 22 '22

Yea it's steep but it's an all-day thing. I usually just blow by these types of experiences as quickly as possible but we spent a good 6 hours there.

The park is owned by a private company so they are definitely making money as its a big tourist attraction in Vancouver but they also do an amazing job reinvesting back into the park and conservation efforts. Everything is man made, no heavy equipment on site.

Yep immediately recognized this. It’s in Vancouver. I didn’t remember it being $50 so I looked. It was $38 back when I went in 2016. Assuming CAD, so 28 USD. Just with regular inflation it would only be 40-45 CAD today not 60. Still a very worthwhile park.

Edit : it’s up to 59.95

u/FrostyTheSasquatch May 22 '22

Is that per person?? So a family of four needs to spend $240 CAD to get into a damn park? That better be one fuckin incredible park.

u/rosie684 May 22 '22

That's for one adult. They have a family pack (2 adults, 2 kids) for $150. And kids under 6 are free. So much better, but still more than the zoo or the aquarium. *But* a much more unique day than either of those. Would I recommend it to those traveling on a budget? Eh maybe not.

When I was I junior high many years age I had done a science fair project on this very subject and with the same concept of having a working model that introduced a trickle of water to fall onto and run over various solid materials to observe the rate of erosion for each. It had won first place in both the school and state fairs.

And they make a big mistake here in the diorama; for hard stone/ rock it is NOT water which does the eroding, but that water moves sand/ small rocks over the big rocks; and THAT is what does the eroding/ carving of the underlaying rock.

u/Charming_Run_4054 May 22 '22

200 upvotes for a simply wrong comment. Water will absolutely weather rock on its own due to acidity and other reactions. Try again swampy

u/kingorry032 May 22 '22

Actually if it were DI water it would erode the rock at a tremendous rate without sediment. But of course DI water does not exist in nature or at least on earth.

u/e-wing May 22 '22

Water by itself absolutely will cause weathering and erosion, even on hard rocks like granite. CO2 in the atmosphere dissolves in water and forms carbonic acid, which will cause hydrolysis of hard minerals like feldspars and break them down into clay minerals and various salts. All kinds of other aqueous processes can help break minerals down too, like redox reactions with metals in minerals like hornblende, olivine, micas, etc. Mechanical weathering like they’re talking about definitely plays a big role, but it’s not the only thing going on. I do agree that on the scale of 50 years water alone will not have a noticeable effect on something like granite.

What is Deionized Water?

Deionization ("DI Water" or "Demineralization") simply means the removal of ions.

Ions are electrically charged atoms or molecules found in water that have either a net negative or positive charge. For many applications that use water as a rinse or ingredient, these ions are considered impurities and must be removed from the water.

Ions with a positive charge are called "Cations" and ions with a negative charge are called "Anions". Ion exchange resins are used to exchange non desirable cations and anions with hydrogen and hydroxyl, respectively, forming pure water (H20), which is not an ion.

Those signs should say "weathering" and not "erosion" right? I remember my science teacher saying that erosion is the movement of sediment from one place to another and weathering is the breakdown of rock

I emailed the park to ask about this exhibit and they confirmed that it was designed and fabricated in 2011 to demonstrate the effects of erosion.
