Despite being spelled differently, the range is named for Archibald McIntyre, the founder of the McIntyre Iron Works at Tahawus, New York.[1] The name McIntyre originally referred only to Algonquin Peak, and was given to the mountain in 1837 by a party led by New York state geologist Ebenezer Emmons. Mountaineer Russell Carson applied the name to the entire range in his accounts.[2] The earliest recorded ascent on the range was made in 1797, when surveyor Charles Brodhead crossed Boundary Peak to mark the boundary of the Old Military Tract.[1][3]
