Little Falls (Potomac River)
From Thomas Jefferson Encyclopedia
Thomas Jefferson's visit to Little Falls, which lay in the Potomac River about four miles up stream from Georgetown probably had a duel purpose. It was an object of natural history of the kind that always attracted him and, without question, he wanted to inspect the canal then under construction that would by pass the Little Falls, whose descent was about thirty-six feet in two miles. This canal was one of the main projects of the Potomac Company's effort to open the river to navigation from Georgetown to Cumberland, Maryland, a distance of 185 miles. Although the Great Falls where the water fell seventy-two feet in about a mile and a half, presented a grander spectacle, they were fourteen miles from Georgetown a distance too great for TJ to have covered at this time.
