Each Spring, from 1870 through 1915, men would drive more than a quarter of a million spruce logs 300 miles from the Connecticut River's headwaters near Quebec to sawmills in Massachusetts. The five-month-long drive was crucial in delivering the lumber needed to build several 19th-century New England cities. This program ventures down the Connecticut River, from the wilderness of northern New Hampshire, to the very depths of the river, to dredge up the forgotten history of these treacherous log drives. Fascinating underwater footage reveals sites containing lost tools, whiskey bottles, and sunken riverboats. In addition, historians share tales of the North Woods lumbermen and daring river drivers - from the danger they faced to the rowdy entertainment they sought.
