Playas are important geomorphic features of the world\'s arid regions and are considered to be very sensitive to hydrologic and climatic changes. Those classified as a geomorphologic unit of desert areas. Playas vary in size from very small depressions of a few tens of m2 to massive tectonic basins, which may extend up to 10, 000 km2. Given the range of origins and scales, these playas display wide range of variability in morphology, hydrology and sedimentology. During the last few decades, playas have received enormous attention due to their significance as indicators of climate change and palaeo-hydrological reconstruction. While the landscape and drainage in playa catchments provide a qualitative assessment of climatic and hydrological regime in the past, playa sediments preserve a wealth of palaeo-environmental information. The geomorphologic types of playa such as Kavir, salt lake and morphologic facies, have been caused the playa as a unique entity for geoarchaeology studies. Iran having more than 60 % desert environments has vast expanse areas of playa units. Central Iran with a wide section of the Lut desert can be a good sample of playa landforms which are an evidence for geoarchaeology and also with high potential for geo-tourism activities. The Yazd region, located center of Iran, constitutes one of the most significant environmental and cultural reserves on Iran, strewn with unique and significant natural geological monuments that are called Geotopes. The Geotopes are the meeting places of elements recording the geological history of each region. Those are the irrefutable witnesses of an everlasting evolution of life on earth, such as volcanoes, caves, gorges, fossilized areas, large geological rifts, ancient mines, geological formation or landscapes chiseled by natural forces throughout the geological ages. Such sites have a special scientific and aesthetic value and could become areas with significant tourist interest. Recent efforts to record, upgrade and exploit a number of geological sites in yazd have produced significant results; the erratic rocks on the Fakhr-Abad, the cirques of Tezergan on Tezergan, the glacial gorge in Deh-Bala, the underground natural dam on Mehriz and sand dam in ashkezar and the granite rocks and the marble mine, the gorge in Taftb, the Kavir and glassi desert in Abar Kooh and Darangier to mention are cased Yazd to be as a natural history museum. Desert of Yazd with extended area of Playa unit as a typical geomorphologic unit involve specific Geotops which reminiscent quaternary climate change and glacier conditions of desert at Pleistocene age. The Playa of desert, there are a number of witnesses in this area that shows this place have had a wetter climatic period in past. This article with new approach to the geomorphologic landforms has been introduced the Geotops and considered those as an evidence for geologic history and geomorphology evolutions and also as a geo-tourism features.
