Wow!
Wow^exp10, in my book.
This solves the "Where do we get our water?" question with a scientific sledgehammer.
That there is at least MILLIONS of metric tons of the wet stuff. ONE crater of many, many, many.
I have goosebumps. This simple, unassuming picture means a great deal.
If this is true, then let me put this in perspective.
The crater walls are as high as the Colorado Rocky Mountains from the bottom of Crater up. And it is almost 3 times the width of our very own crater in Arizona. The little looking ice pond would be about a mile across.
