This week, we had two days of temperatures above 90° -- and then Brimson almost broke the record with a low of 30°.

But nothing tops the week of July 7-13 in 1936, when the entire country sweltered under a series of heat waves. 17 of the 48 contiguous states and two Canadian provinces tied or broke their all-time heat records and many of those records are still unbroken.

In Duluth, six of those records still stand: doubly impressive when you learn temperatures were only recorded by the lake in those days.

Plus berries, bugs, basswood and butterflies this morning on Backyard Almanac.
