Why is White Sands Desert in New Mexico so purely white?

it is gypsum
it is very fine grained sand
it iswhite quartz
it is an optical illusion
White Sands, having 442 total square kilometers of dune fields, is the world's largest surface deposit of gypsum. Unlike other desert sands, it is cool to the touch, due to the high rate of evaporation of surface moisture and the fact that the sands reflect, rather than absorb, the sun's rays.
