Explanation:

Cumberland gap is a pass which flows through the cumberland mountains in the Appalachian mountains. In 1750, Dr. Thomas, an English naturalist led a small group of explorers to that cumberland gap after getting to know about it from the native American description of the pathway. He called it "the cave gap".

He named the river north of the cave gap as Cumberland river after the Duke of cumberland, son of Britan's king George II. It is now a part of the Cumberland national Historical park.

Historical significance:

American civil war happened in and around the cumberland gap. These battles are commonly known as 'battle of cumberland'"
