Lefka Ori (, meaning "White Mountains") or Madares (Μαδάρες from the Cretan Greek μαδαρός meaning "without coverage, bald, bare of any vegetation for high mountain areas") is a mountain range located in Western Crete, in the Chania prefecture. The White Mountains or Lefka Ori occupy a large part of the centre of West Crete and are the main feature of the region. They consist mainly of limestone, from light grey to bluish or black color. The "White Mountains" have got their name from the perpetual white or off white color of their peaks as the off white of limestone during the summer and fall interchanges with the snow that covers the peaks until late in spring.
