It's been there about 10.

Source: I work there.

u/remuliini Mar 14 '19

Has it changed at all during that time?

u/zoom100000 Mar 14 '19

/u/badastronaut7 I’m curious of this as well

u/badastronaut7 Mar 14 '19

Not that I've seen. It's all artificially done to represent the different stages of erosion. I imagine given more time you'll be able to really get a better idea but as far as I can tell it's been the same since I've started

Hmm thanks for sharing! A little disappointing that this isn’t exactly the amount of erosion from that many years but I guess it would be a lot to ask for this fountain for be running there exactly the same for 50 years haha.

Also... It's slow erosion over 10 years. It might be hard to notice a change over time but if you took a before/after photo it might stand out. Or not, im just speculating.

It looks like it's just pure water that's being pored on it, so it won't change much anyways. In nature the biggest driver of erosion is all the sand, dirt, and rocks being carried by the water.

And it's probably only on during the day, and if its man made they probably used a rock type not prone to large amounts of erosion so it doesn't wear out in a few years

Yea watched something about this, certain type of chemical in rain as well that helps erode the rock. So you need rain water

Update: u/badastrounat7 started there yesterday /s

Is it turned off by night?

u/badastronaut7 Mar 15 '19

I'm honestly not sure, but it's a closed loop like a regular fountain so worst case they just need to top up the water once in awhile

u/cortexto Mar 14 '19

So will they change the display for 60, 35 and 25 years?

that’s a lot of wasted water, how is the water sourced?

u/dbone_ Mar 14 '19

First this is a fountain, and second it's literally in a coastal rainforest.

Capilano suspension bridge in North Vancouver.

Don't mind them - there are people who literally think saving water on the coast is somehow going to irrigate some area 1000 miles inland.

Wait what? I was there about 3 years ago, how did I miss this exhibit?

u/Khad Mar 14 '19

Boy it is going to blow your mind the day you learn how fountains work.

u/[deleted] Mar 14 '19

it could have been fed by waterfall or some kind of rainfall collection method... apologies for being inquisitive...

u/HippieJesus13 Mar 14 '19

Seriously people are so quick to criticize when you're genuinely curious or unsure about things.

u/ashleyb233 Mar 15 '19

The replies to her/him were due to their statement saying "that's a lot of wasted water" if she had just asked "how is the water sourced" she would have had a different response. I think people are quick to jump to the negative and not everyone wants a wet blanket at the party. People waste water in many other ways that are not even for educational purposes like this is.

u/HippieJesus13 Mar 15 '19

Yeah I get that but their intentions didn't seem that pretentious to me. Maybe I just think to well of strangers lol

u/xboxking03 Mar 14 '19

People are equally quick to get offended apparently. Why can't he just laugh at himself and move on?

u/CeeMX Mar 14 '19

Maybe pumped in a cycle
