RE:and the term Indian Summer was invented
I heard the esteemed meteorologist on WJR decades ago say “Itis not truly Indian Summer unless there was a full frost followed by warming, not just cool weather and then not cool.”
However, I saw maybe half a dozen different views on that.
Also, this polluting action by the Native Americans which would be totally banned today:
From MPRNews.org October 12, 2017.
When European settlers first came across the phenomenon in America it became known as the Indian’s Summer. The haziness of the Indian Summer weather was caused by prairie fires deliberately set by Native American tribes. It was the period when First Nations/Native American peoples harvested their crops.
As I learned it growing up in New England, the term referred to the warm period after first frost, when the Indians, who weren’t bright enough to have prepared for winter, came around begging or stealing food.
