'''Bajestan Playa''' (also known as '''Bajestan Salt Desert''' or '''Kavīr-e Namak Bajestan''') is a large [[Dry lake|playa]] and [[salt pan (geology)|salt flat]] located in [[Bajestan County]], [[Razavi Khorasan province]], [[Iran]]. It is the second largest playa in Iran and one of the major playas in the Middle East, covering an area of approximately 3,725 square kilometers.<ref name="ui-ac-2024">{{cite journal |last1=Haghighi Gorji |first1=S. |last2=Torshizian |first2=H.

== Geography ==
The playa is situated in the southern part of [[Razavi Khorasan province]], approximately 260 kilometers south of [[Mashhad]]. Its geographical coordinates are 34°53′07″N 58°07′45″E.<ref name="geonames">{{cite web |title=Kavīr-e Namak Bardaskan |url=https://www.geonames.org/29719/kavir-e-namak-bardaskan.html |website=GeoNames |access-date=9 August 2026}}</ref> The playa is surrounded by volcanic and volcanoclastic rocks and has a gentle slope from its margins toward the center.<ref name="ui-ac-2024"/>

== Geology and Climate ==
The Bajestan Playa is classified as a [[closed basin]] with an [[arid climate]]. The region experiences hot summers and cold winters, with significant temperature fluctuations between day and night. The playa's surface consists of [[clay]], [[salt crust]]s, and [[ephemeral lake]]s that form during rare rainfall events. Geological studies have identified three main clusters of ionic composition in the playa's [[brine]]s, dominated by [[magnesium sulfate]] [[facies]].<ref name="ui-ac-2024">{{cite journal |last1=Haghighi Gorji |first1=S. |last2=Torshizian |first2=H.

== Name and Etymology ==
The name "Bajestan" has historical roots and appears in various historical texts, including the [[Qajar]]-era [[travelogue]] "Tohfat al-Foghara" (''The Gift to the Poor'') by Mirza Ali Khan Naini (Moshataqi), written in 1300 AH ([[1882]] AD).<ref name="geography-gonabad">Pour Ebrahim, Hossein. ''Joghrafia-ye [[Gonabad]]'' (Geography of [Gonabad]), pp. 39</ref> The name has been consistently used in academic literature, including a 2024 study from the University of Isfahan, and in international media outlets such as Iran Press and iFilmTV.<ref name="iranpress">{{cite web |title=Bajestan Playa; land of unknown in Iran's Khorasan Razavi |url=https://iranpress.com/content/45856/ |website=Iran Press |access-date=9 August 2026}}</ref><ref name="ifilmtv">{{cite web |title=Bajestan desert: An unknown gem |url=http://en.ifilmtv.ir/News/Content/35854 |website=iFilmTV |access-date=9 August 2026}}</ref>

The playa has been officially recognized as a national natural heritage site in Iran and is a member of the "Gheshka" (Desert Cities of Iran) tourism group, which aims to promote desert tourism in the region.<ref name="gheshka">{{cite web |title=شهرهای عضو گشکا دوباره دور هم جمع می‌شوند |url=https://www.isna.ir/news/1404012010307/ |website=ISNA |date=9 April 2025 |language=fa}}</ref>

== Research and Significance ==
Scientific research on the Bajestan Playa has focused on its hydrogeochemistry, brine evolution, and potential for mineral resources, including [[lithium]]. The playa is also recognized as a significant source of dust in the region.<ref name="elsevier-2023">{{cite journal |last1=Khosravichenar |first1=A. |last2=Aalijahan |first2=M. |title=Assessing a multi-method approach for dryland soil salinization – The example of the Bajestan region |journal=Ecological Indicators |date=2023 |volume=154 |doi=10.1016/j.ecolind.2023.110811}}</ref><ref name="harvard-2022">{{cite web |title=Assessing the impact of climate change on three decades of soil salinity dynamics in the Bajestan Playa |url=https://ui.adsabs.harvard.edu/abs/2022EGUGA..2412243K/abstract |website=Harvard ADS |date=2022}}</ref>
