The earliest written use of the name, spelled Rontaks, was in 1724 by the French missionary Joseph-François Lafitau. He defined it as tree eaters. In the Mohawk language, Adirondack means porcupine, an animal that may eat bark. The Mohawks had no written language at the time so Europeans have used various phonetic spellings. An English map from 1761 labels it simply Deer Hunting Country and the mountains were named Adirondacks in 1837 by Ebenezer Emmons.
