Piles of Snow
According to weather.com, Boston had 110 inches of snow this winter. Sure, some of this snow melted at different times—but much of it didn’t. What do you do with all this snow? Suppose that there was just 50 inches (1.27 m) of snow that covered an area that was 1 square mile. If you take all of this snow and move it to a football field, it would stack 600 meters high (almost 2,000 feet). So you can see the problem with the massive amounts of Boston snow. If you want to clear the roads, you have to put the snow somewhere. This makes giant piles of snow.
Snow Mixed With Trash
When trucks plow snow covered roads, they don’t just get the snow. They also gather up stuff that was on the ground before the snow (and after the snow). Typically this stuff is call “trash.” With regards to melting, there’s a big difference between snow and trash.
