@michaelharrison3046 BTW--I come as 3rd gen mining background, more informed but biased in favor of extractive industries done right
There won't be an open pit or anything spectacular changed about that valley. Nothing much cleaner than simply pumping an extremely salty shallow aquifer that could never be used for anything else, evaporating the water in the sun and wind and extracting a couple components. It's mostly solar powered with incredible efficiency. :D
Those salts are from recurring lakes without outlets, filled and evaporated by climate changes for M's of yrs, massive glacial till/runoff, made lakes far bigger than the Great Lakes at times in recent past Nevada.
As glaciers advance and retreat, repeat, fresh water (always some natural salts in fresh) gradually becomes far saltier than the oceans. Lake may be Yuge but shrinks to the lowest points, again, concentrating the salts. The geology retains the brine indefinitely.
I assume they are dropping the small valley floor a little via the removed brine and the surface will have more salts than it used to...pending the next time ice sheets again level the N. Hemisphere, most recent only ended around 14k yrs ago, yesterday in geologic terms and well within human experience...tangent.
Otherwise it will be more or less the "wasteland" it always was.
Pardon caring on, sheesh.

@staralioflundnv At 1st blush I would think seismic activity, even severe quakes, would have negligible effect on zone beyond plug due to above stated reason....given distance underground.
It would of course be of concern for the surface infrastructure. I'd want everything possible to be underground where it's safe, turbine, electrical, etc. Also having everything at constant temperature and protected from snow drifts, freezing and so on.
Rocks come off the cliffs like bullets and pass right thru any manmade object, vehicles, structures or whatever, even with common modest 7 mag quakes. Dad would order everyone to stay underground until aftershocks dissipated.
Funny tangent story but relevant: Easy Go is about 3 miles plus long (called Easy Going because prior to that tunnel they had to transport all the 100s of employees up treacherous switchbacks on steep avalanche prone roads to around 10k alt original access and offices)
Ray Gray (dad) designed the tunnel and the ditch on the side of it, for most of the length of the long tunnel mining process "Gray's ditch" was a standing joke bc it was dry until near the end when hitting abundant water and it filled to the top.
This was not trivial bc the entire tunnel must be bigger and more expensive to accommodate the ditch. Dad simply measured the flow from many existing tunnels per length and averaged the results to figure the flow rate needed and it turned out to be on the money, pun intended. Some luck no doubt but everyone forgot the Gray's Ditch joke after that.
SO...that plug could have been installed deep under and still capture most of the water available. In some places the water would blast out against the train cars as you passed, it was like Disneyland but better.

@jdearr1 A few fun facts from the IPCC:
1) hurricanes have NOT increased in frequency or intensity in the last century (true for extreme weather in general)
2) Greenland ice sheet has melted at the same rate for the last 80 yrs.
3) human induced climate change will not have significant economic impact globally this century. (actually an opinion, not a fact yet obviously)
Extra CO2 simply does make plants grow better and more drought tolerant, simple FACT regardless of it's inconvenience to media indoctrination. Popular media has never understood nor cared to understand science. They are all about gaining your attention, nothing else.
Levels have been way LOW in recent millions of yrs which happens to coincide with climate instability and the devastating ice age which we are still in...just happen to be in a glacial minimum currently which don't last as long as the destructive maximums. Dangerously low to the point that during glacial maximums it approaches levels where mass plant extinctions would begin, causing general mass extinction like no one has even contemplated.
Balance??? WTF are you talking about? There is no such thing in this context. What makes you think this historically extremely low CO2 level is best for us or life on Earth? CO2 is as essential for plants as water and sunlight. Calling it a pollutant is utterly asinine (not you maybe but governments have) and shows just how out of whack the popular climate religion is. Sure not based on science or reality.
Life flourished at 2000ppm, even 10,000. A modern tight home will often have 2000ppm inside. Commercial greenhouses are also typically kept at around 2000, you think they do that for entertainment?
Not like this planet was made for us but we are a part of nature as surely as plankton and whales. Be quite astounding if 280ppm, record lows, just happened to be ideal, hmmm?
