The Great Snow of 1717

The Great Snow of 1717 was a series of snowstorms between February 27 and March 7, 1717 (Gregorian calendar) that blanketed the colony of New York and the New England colonies with five or more feet (1.5 or more meters) of snow, and much higher drifts. Snowfall may have occurred elsewhere, but settler population was sparse outside of New England at that time. The Great Snow is considered one of the storms in New England, often compared to the Great Blizzard of 1888 in severity.

The winter, even prior to the Great Snow, had been the worst in memory. The temperatures had not been unusually cold, but in December 1716, there had already been snow to the depth of 5 feet (1.5 m). By the end of January, there were drifts 25 feet (7.6 m) high in a few places, overwhelming the people living in New England at the time.

There had been a series of volcanic eruptions circa 1716. Ash circulating the globe in the upper atmosphere from the eruptions of Mount Kirishima in Japan, Kelud in Indonesia and Taal Volcano in the Philippines likely contributed to the exceptional New England snowfall.

The great snow, depending on the source, began on February 27 or March 1. On February 27 a typical New England nor'easter passed through, with snow falling on some areas and other places receiving a mix of snow, sleet, and rain. The first major snowstorm occurred on March 1, with another on the 4th, and a third, the worst among the three, on the 7th. At some points, the snow would lighten and stop, but the sky would remain cloudy, showing no signs of clearing.

Some of the oldest Native Americans had said that even their ancestors never spoke of a storm of this magnitude. Boston received around 40 inches (100 cm) of snow, while some places north of the city reached up to 60 inches (150 cm). In Hampton, Massachusetts, the snow was so deep that people could only leave their houses from the second floor on the lee side of the house, implying actual snow depths of as much as 8 feet (2.4 m) or more. Many single-story homes were buried completely, without even the chimney showing. On the larger residences, drifts reached the third-story window on the windward side. Large expanses of snow were 10–15 feet (3.0–4.6 m) deep, with some significant drifts 20 feet (6.1 m) deep.
