Devastating wildfires and droughts are not the only natural catastrophes that California will continue to face. According to new research published on Friday, a disastrous megaflood could bring so much water to some areas of the state that it could completely drown entire stop signs on a neighborhood street.
There was a vast flood in California in 1862 that supposedly killed about one percent of the state’s population. It would probably be really famous if Mark Twain had arrived in time, but he didn’t get to California until a little later.
