"Cairngorm" is not Mount Cairngorm or Cairngorm Peak. Just "Cairngorm." It was named by surveyor Morrison Bridgland after a group of granitic mountains in the Scotland Highlands. "Gorm" in Gaelic means blue-green and in July and early August, the upper slopes of the mountain do have shades of green on them. However the ancient name for the Scottish Crairn Gorm is "Monadh Ruadh," and this meant "red mountains," which the peaks of the Victoria Cross Range certainly are.
