Question
Is it true that it snowed red in New England during the 1930s? What caused this? Can it snow other colors, like black? Has this ever occurred in Buffalo, NY?

Answer
Hi Stephen

Red snow is caused by algae in the snow. It can be in different colors. The cause is the right chemistry along with the right temperatures to have this phenomenon. Also, red dust can also be responsible.

New England did experience red snow in the 30's:
