why are the nilgiris called the blue mountains
The Nilgiris District The history of peoples settled in the Nilgiri hills has been recorded for several centuries. The Blue Mountains were likely named for the widespread blue Strobilanthes flower or the smoky haze enveloping the area.
Blue Ridge Mountains The Blue Ridge contains the highest mountains in eastern North America south of Baffin Island. About 125 peaks exceed 5,000 feet (1,500 m) in elevation.[5] The highest peak in the Blue Ridge (and in the entire Appalachian chain) is Mt. Mitchell in North Carolina at 6,684 feet (2,037 m). There are 39 peaks in North Carolina and Tennessee higher than 6,000 feet (1,800 m); by comparison, in the northern portion of the Appalachian chain only New Hampshire's Mt. Washington rises above 6,000 feet. Southern Sixers is a term used by peak baggers for this group of mountains.[6]
