Science says, Lake Michigan is very blue! Just look at that picture above. Researchers say a number of factors have contributed to making this so. According to Penn State Emeritus Professor Doctor Craig Bohren water not only reflects a blue sky, but it also radiates blue. That amount of blue depends on factors like a cloudy sky and a certain something that’s been turning Chicago’s waters green. I’m sure you’ve heard the joke, “Chicago is dying the river green-ER for St. Patrick’s Day…”
That green is caused by algae and Bob Shuchman and Mike Sayers of Michigan Tech say the lake is much less green than it used to be thanks to a significant decrease in algae. Less algae and a bluer lake sure do make for very beautiful views!
