Guelta

A guelta (Arabic: قلتة, also transliterated qalta or galta) is a pocket of water that forms within rock formations in the Sahara Desert and Arabian Desert. The term is of Arabic origin and specifically refers to oases that emerge in rocky landscapes in Arab regions, particularly in countries like Algeria and Saudi Arabia.

A guelta is a natural water pool that forms in rocky basins and often serves as a crucial water resource in arid regions. It has been known in Arabic by other names, such as Waqb (a depression in the ground or rock). When multiple gueltas occur in close proximity, they are collectively called a Nadheem.

Gueltas are known for their ability to retain water for extended periods, sometimes throughout the year, especially if fed by springs. This makes them essential for survival in arid climates, where they can remain a source of water even during the dry season.
