What’s with that “notch” in CT’s northern border?

Take a look at the northern border of the state of Connecticut and you’re likely to notice something intriguing. Along the northern border, there is a “notch” that cuts into the state. Why does it exist? What is its function?

Curious about the history, I spoke with two experts on the matter. One from Suffield, CT and the other from Southwick, MA. Both individuals were able to explain the history of the “notch” and its current status.
