If you remember the house in Juneau, Alaska, that was dramatically washed into the river during a flood about a month ago, there's a shocking detail buried in the middle of this story: that house started out 50 feet from the river's edge. Another house similarly demolished was 100 feet back. 😮
@grammargirl Assuming this is the same house I'm thinking of, I found it on Google Maps when it was first in the news and was surprised how far it seemed to be from the river. I assumed then there had been gradual erosion between the incident and Google's last photo. Amazing that was all at once!
@grammargirl
They used to think a single flood like this dug the entire Columbia River Gorge
Now they figure it was about 40 floods, each caused when a glacier melted, freeing up water behind it that was suddenly “13 x the flow of the Amazon River” https://en.m.wikipedia.org/wiki/Missoula_floods
None of that millions of years stuff like the Grand Canyon
The Gorge was blown out in a fraction of that with its explosive flooding
But if we don’t stop the water rising, nobody will have any high ground
