Lake disappears

Lake disappears

"SANTIAGO, Chile (AP) -- A five-acre glacial lake in Chile's southern Andes has disappeared -- and scientists want to know why.

Park rangers at Bernardo O'Higgins National Park said they found a 100-feet-deep crater in late May where the lake had been in March. Several large pieces of ice that used to float atop the water also were spotted.

"The lake had simply disappeared," Juan Jose Romero, head of Chile's National Forest Service in the southernmost region of Magallanes, said Wednesday. "No one knows what happened."

A group of geologists and other experts will be sent to the area 1,250 miles southeast of Santiago in the next few days to investigate, Romero said.

One theory is the water disappeared through cracks in the lake bottom into underground fissures. But experts do not know why the cracks would have appeared because there have been no earthquakes reported in the area recently, Romero said.

A river that flowed out of the lake was reduced to a trickle."

I guess this is due to global warming too...right Techs?

Weird...

 

[sunzt]

Water dependent aliens ran out of water and took ours!

 

[techs]

Dune, Arrakis, Earth.
All the same.

global warming caused it. The temperature increased by .000000000001% last year and caused the entire lake to evaporate instantly.

It will happen to a lake near you soon, too!

If I was in the area, I'd GTFO right now. Might be nothing, but I'd be thinking Volcanic Activity. At least take a couple weeks vacation.

 

[HombrePequeno]

What's the reason for bringing up global warming for this?

Oh yeah, you just wanted to troll.

2 lakes in Arizona (1 natural, 1 man-made) have sprung leaks in the past 10 years. The man-made lake was "repaired" and the natural lake is still dry... gone forever I guess.

:thumbsup:

Also, a couple weeks are nothing in geological terms. I would hope plentiful seismic sensors were in place before I would remotely feel comfortable.

Actually if you notice there was huge retreat in the glacier that fed that lake.

The water table dropped so it was inevitable that a leak developed and drained that lake to the new water table level.

So it was Global Warming that caused it.

Sort of like the glaciers that have recently melted in Europe, revealing medieval buildings from when the earth was warmer several hundred years ago? Wonder how humans warmed the earth back then.......

SO? It's not the first lake that drained away due to some fault or fissure opening. By comparing aerial photos from past (WWII)Tundra surveys, thousands of Artic lakes have disappeared. That may be more serious news.

There was a lot more volcanic activity.

If there is limestone in the area, new drainages related or unrelated to global warming can develop very rapidly due to sinkhole openings. And in a mountainous region water tables
can vary widely and be perched. But we are speculating anyway as a team of scientists are being sent to the area. But five surface acres and up to 100 feet deep is a heck of a lot of water and its exit point to the surface has to somehow scar the land where it exited if it exited rapidly. Even if its a trickle now. But its also possible that the water sources from the glacier feeding it developed alternative drainages and that plus multiple small fissures allowed the water to slowly drain away faster than it was replaced.

Why do too much speculating when we should know more in a few weeks. And they likely will get answers by adding a tracer element to water and see where it can be detected downslope. Twenty or more mile dye traces are common.

Something like this happened in Florida a few years back. There was a lake that sat on top of an underground aquifer. There was a "plug", a large collection of boulders, that sat on top of the aquifer. One day the "plug" fell out and the lake drained away in a few days.

Could have happened here... Glacial lakes are so fickle...

So that's how they did it. Sacrificial virgins must have been at a premium back then.

I think that this goes to show that large events can happen very quickly, even without human intervention. Would anyone have guessed before that a very large lake (5 acres, 100ft deep) could have completely disappeared within two months?

 

[imported_Shivetya]

who is to say that Global Warming didn't form that lake 30 years ago?

How long does it have to be around to get lake status? 30 years in the life of the earth is kinda like it being a giant puddle!




still many glaciers are expanding, its just far easier to make hay out of the ones that aren't.

 

[SilthDraeth]

Actually I posted the thread because it was interesting. I just added the Troll for fun. I am glad Techs took it as a jest, bringing up Dune.

Thanks for some insight Lemon Law.

A troll and a call out thread... well done Silth, well done.

I can't believe no one has blamed this on Bush yet...

If Dubbya hadn't taken us all willy-nilly into Iraq and started murdering brazillians of babies to feed his monsterous ego, this lake would still exist.

 

[Lemon law]

Moderator smacks Whoozyerdaddy with a large, wet Lake Trout.

Well, if the moderator goes looking for lake trout to smack you with in the lost lake of this thread---you are going to get smacked by a dead and dry lake trout. But I suspect lake trout of a given side weigh less and smack softer in the dead and dry state--but on the downside---they can stink more.

Quick Quick---call off the science team and send the moderator to get the answers. Whoozeyerdaddy will post the definitive answers when he reports on the resulting smackdown.
The thriller from the chiller in the Andies.

 

[WhipperSnapper]

So, has anyone determined the cause of this mysterious lake disappearance yet?
