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.
Flint Hills The Flint Hills historically known as Bluestem Pastures or Blue Stem Hills,[2] is a region in eastern Kansas and north-central Oklahoma named for the abundant residual flint eroded from the bedrock that lies near or at the surface. It consists of a band of hills stretching from Kansas to Oklahoma, extending from Marshall and Washington counties in the north to Cowley County, Kansas and Kay and Osage counties in Oklahoma in the south, to Geary and Shawnee counties west to east.[3] Oklahomans generally refer to the same geologic formation as the Osage Hills or "The Osage."
