Hes an agenda troll. Marquette clearly has missing data from the 1960s, just as Toledo did in the graph he posted. The snowiest winter on record for the Keewenaw Peninsula in the U.P. (an even snowier local than MQT) is actually the very cold winter of 1978-79 with like 380". The freezing of Lake Superior is a different beast than that of the other Great Lakes. The 1960s were much colder winters than the mild 1950s, but the real cold winters decade was the 1970s. Marquettes snowfall is taken outside of the city in Negaunee, an area that is actually MUCH snowier than the city itself. very micro-climatey there. Not sure if those 1960s numbers werent in Negaunee but rather in the city itself, or if it was just missing data.
